### Vollständige Analyse der Infrastructure-Module
|
||||||
|
|
||||||
|
Ich habe eine umfassende Analyse aller Infrastructure-Module durchgeführt. Hier ist meine Bewertung der Implementierungen:

|
|
||||||
|
## Zusammenfassung
|
||||||
|
|
||||||
|
Die Infrastructure-Implementierung ist **insgesamt sehr gut strukturiert und professionell umgesetzt**. Die Architektur folgt modernen Best Practices mit klarer Trennung von API und Implementierung. Es gibt jedoch einige Inkonsistenzen und potenzielle Konflikte, die behoben werden sollten.

## Detaillierte Analyse nach Modulen
|
||||||
|
|
||||||
|
### ✅ Gateway Module - **Exzellent**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Vollständige API-Gateway-Implementierung** mit Spring Cloud Gateway
|
||||||
|
- **Moderne reaktive Architektur** (WebFlux, Netty)
|
||||||
|
- **Umfassende Cross-Cutting Concerns**:
|
||||||
|
- ✅ Correlation ID Filter für Request-Tracing
|
||||||
|
- ✅ Enhanced Logging Filter mit strukturiertem Logging
|
||||||
|
- ✅ Rate Limiting mit Memory-Leak-Schutz
|
||||||
|
- ✅ JWT-basierte Security mit Keycloak-Integration
|
||||||
|
- ✅ Circuit Breaker pro Service (Resilience4j)
|
||||||
|
- ✅ Retry-Mechanismen
|
||||||
|
- ✅ Fallback-Controller für Service-Ausfälle
|
||||||
|
- **Exzellentes Monitoring**:
|
||||||
|
- ✅ Custom Metrics mit Micrometer
|
||||||
|
- ✅ Pfad-Normalisierung zur Vermeidung von Kardinalitätsproblemen
|
||||||
|
- ✅ Prometheus-Integration
|
||||||
|
- ✅ Health Indicator für Downstream-Services
|
||||||
|
- **Vollständige CORS-Konfiguration**
|
||||||
|
- **Gute Test-Abdeckung** (7 Test-Dateien)
|
||||||
|
- **Detaillierte Dokumentation** (README-INFRA-GATEWAY.md)
|
||||||
|
|
||||||
|
#### Empfehlungen:
|
||||||
|
- ✅ Sehr gut: Separate Bean-Namen für Redis ConnectionFactory (`eventStoreRedisConnectionFactory`)
|
||||||
|
- ⚠️ Das Gateway importiert `redis-event-store` als Dependency (Zeile 32 in build.gradle.kts) - **ist das beabsichtigt?** Ein Gateway sollte normalerweise keinen Event Store benötigen.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### ✅ Cache Module - **Sehr gut**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Saubere API-Implementierung Trennung**:
|
||||||
|
- `cache-api`: Provider-agnostische Interfaces
|
||||||
|
- `redis-cache`: Konkrete Redis-Implementierung
|
||||||
|
- **Vollständige Cache-Features**:
|
||||||
|
- ✅ TTL-Unterstützung
|
||||||
|
- ✅ Connection State Tracking
|
||||||
|
- ✅ Health Monitoring
|
||||||
|
- ✅ Jackson-basierte Serialisierung
|
||||||
|
- **Redis-spezifische Properties** (`RedisProperties`) mit sinnvollen Defaults
|
||||||
|
- **Connection Pooling** aktiviert
|
||||||
|
- **@ConditionalOnMissingBean** für flexible Bean-Konfiguration
|
||||||
|
|
||||||
|
#### Empfehlungen:
|
||||||
|
- ✅ Keine Bean-Name-Konflikte mit Event Store (verwendet `redisConnectionFactory` ohne Qualifier)
|
||||||
|
- ⚠️ Beide Module (cache und event-store) verwenden unterschiedliche Property-Prefixe (`redis` vs `redis.event-store`) - **gut, aber sollte dokumentiert sein**
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### ✅ Event Store Module - **Sehr gut**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Saubere API-Implementierung Trennung**:
|
||||||
|
- `event-store-api`: Provider-agnostische Interfaces
|
||||||
|
- `redis-event-store`: Redis Streams Implementierung
|
||||||
|
- **Event Sourcing Features**:
|
||||||
|
- ✅ Append Events mit Optimistic Locking
|
||||||
|
- ✅ Redis Streams für Pub/Sub
|
||||||
|
- ✅ Consumer Groups
|
||||||
|
- ✅ Event Replay-Fähigkeit
|
||||||
|
- ✅ Concurrency Exception Handling
|
||||||
|
- **Separate Redis Connection Factory** mit Qualifier (`eventStoreRedisConnectionFactory`)
|
||||||
|
- **Eigene Properties** (`RedisEventStoreProperties`) mit Prefix `redis.event-store`
|
||||||
|
- **Gute Integration** mit core-domain (DomainEvent)
|
||||||
|
|
||||||
|
#### Potenzielle Konflikte:
|
||||||
|
- ⚠️ **WICHTIG**: Beide Redis-Module (cache + event-store) könnten Konflikte verursachen, wenn sie im selben Service verwendet werden:
|
||||||
|
- Unterschiedliche ConnectionFactory-Namen verwendet ✅
|
||||||
|
- Unterschiedliche Template-Namen (`redisTemplate` vs `eventStoreRedisTemplate`) ✅
|
||||||
|
- Unterschiedliche Property-Prefixe ✅
|
||||||
|
- **Aber**: Beide verwenden Jackson-Serializer - könnte zu Konflikten führen wenn unterschiedliche Konfigurationen benötigt werden
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### ⚠️ Auth Module - **Gut, aber Inkonsistenzen**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Keycloak-Integration** für Benutzerverwaltung
|
||||||
|
- **Spring Security OAuth2 Resource Server**
|
||||||
|
- **Actuator-Endpunkte** für Health Checks
|
||||||
|
|
||||||
|
#### ⚠️ **Inkonsistenzen gefunden**:
|
||||||
|
|
||||||
|
1. **Consul Discovery deaktiviert** (`enabled: false` in application.yml)
|
||||||
|
- Gateway erwartet `lb://auth-service` für Load Balancing
|
||||||
|
- Auth-Server registriert sich **nicht** in Consul
|
||||||
|
- **Folge**: Gateway kann auth-service nicht finden! ❌
|
||||||
|
- **Lösung**: Entweder Consul aktivieren ODER Gateway-Routing auf feste URL ändern
|
||||||
|
|
||||||
|
2. **Minimale Management-Endpunkte**
|
||||||
|
- Nur `health` und `info` exponiert
|
||||||
|
- Andere Services haben mehr Monitoring-Endpunkte
|
||||||
|
- **Empfehlung**: Konsistenz mit anderen Services herstellen
|
||||||
|
|
||||||
|
3. **Keine Monitoring-Client-Dependency**
|
||||||
|
- Andere Services nutzen `monitoring-client` Bundle
|
||||||
|
- Auth-Server hat eigene manuelle Konfiguration
|
||||||
|
- **Empfehlung**: Wiederverwendung des `monitoring-client` Moduls
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### ✅ Messaging Module - **Sehr gut**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Klare Trennung**:
|
||||||
|
- `messaging-config`: Zentrale Kafka-Konfiguration
|
||||||
|
- `messaging-client`: High-Level Producer/Consumer
|
||||||
|
- **Reactor Kafka** für reaktive Streams
|
||||||
|
- **Wiederverwendbare Konfiguration**
|
||||||
|
- **Korrekt als Library konfiguriert** (bootJar disabled)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### ✅ Monitoring Module - **Sehr gut**
|
||||||
|
|
||||||
|
#### Stärken:
|
||||||
|
- **Klare Trennung**:
|
||||||
|
- `monitoring-client`: Wiederverwendbare Library für alle Services
|
||||||
|
- `monitoring-server`: Eigenständiger Zipkin-Server
|
||||||
|
- **Vollständiges Stack**:
|
||||||
|
- ✅ Micrometer + Prometheus
|
||||||
|
- ✅ Zipkin Tracing
|
||||||
|
- ✅ Spring Boot Actuator
|
||||||
|
- **Bundle-basierte Dependencies** - sehr wartbar
|
||||||

## 🔴 Kritische Probleme
|
||||||
|
|
||||||
|
### 1. **Auth-Service nicht in Consul registriert**
|
||||||
|
```yaml
|
||||||
|
# infrastructure/auth/auth-server/src/main/resources/application.yml
|
||||||
|
spring:
|
||||||
|
cloud:
|
||||||
|
consul:
|
||||||
|
discovery:
|
||||||
|
enabled: false # ❌ PROBLEM
|
||||||
|
```
|
||||||
|
|
||||||
|
**Aber Gateway erwartet:**
|
||||||
|
```yaml
|
||||||
|
# infrastructure/gateway/src/main/resources/application.yml
|
||||||
|
- id: auth-service-route
|
||||||
|
uri: lb://auth-service # ❌ Kann nicht aufgelöst werden!
|
||||||
|
```
|
||||||
|
|
||||||
|
**Auswirkung**: Gateway kann Auth-Service nicht erreichen!
|
||||||
|
|
||||||
|
**Lösungsoptionen**:
|
||||||
|
- **Option A** (empfohlen): Consul Discovery im Auth-Server aktivieren
|
||||||
|
- **Option B**: Gateway-Route auf feste URL ändern: `uri: http://localhost:8087`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2. **Gateway importiert redis-event-store**
|
||||||
|
```kotlin
|
||||||
|
// infrastructure/gateway/build.gradle.kts:32
|
||||||
|
implementation(project(":infrastructure:event-store:redis-event-store"))
|
||||||
|
```
|
||||||
|
|
||||||
|
**Frage**: Warum benötigt das Gateway einen Event Store?
|
||||||
|
- ❓ Wird für Gateway-eigene Events verwendet?
|
||||||
|
- ❓ Historische Dependency, die nicht mehr benötigt wird?
|
||||||
|
|
||||||
|
**Empfehlung**:
|
||||||
|
- Falls nicht benötigt: Dependency entfernen
|
||||||
|
- Falls benötigt: Dokumentieren, wofür das Gateway Events speichert
|
||||||
|
|

|
||||||
|
## ⚠️ Potenzielle Konflikte
|
||||||
|
|
||||||
|
### 1. **Redis-Module Nebeneinander**
|
||||||
|
Wenn ein Service **beide** Redis-Module verwendet (`redis-cache` + `redis-event-store`):
|
||||||
|
|
||||||
|
**Gut gelöst**:
|
||||||
|
- ✅ Separate ConnectionFactory-Namen
|
||||||
|
- ✅ Separate Template-Namen
|
||||||
|
- ✅ Separate Property-Prefixe
|
||||||
|
|
||||||
|
**Potenzielle Probleme**:
|
||||||
|
- ⚠️ Beide verwenden Jackson-Serializer - könnte theoretisch kollidieren
|
||||||
|
- ⚠️ Beide verwenden gleiche Redis-Instanz mit unterschiedlichen Databases
|
||||||
|
- ⚠️ Dokumentation fehlt für gleichzeitige Nutzung
|
||||||
|
|
||||||
|
**Empfehlung**:
|
||||||
|
```kotlin
|
||||||
|
// Dokumentieren in README oder Code-Kommentaren:
|
||||||
|
// WICHTIG: redis-cache verwendet Database 0
|
||||||
|
// WICHTIG: redis-event-store verwendet Database 1 (oder configure via properties)
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2. **Inkonsistente build.gradle.kts Patterns**
|
||||||
|
|
||||||
|
**Verschiedene Ansätze für Library-Module**:
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// messaging-config/build.gradle.kts
|
||||||
|
tasks.getByName("bootJar") {
|
||||||
|
enabled = false
|
||||||
|
}
|
||||||
|
|
||||||
|
// redis-event-store/build.gradle.kts
|
||||||
|
tasks.bootJar {
|
||||||
|
enabled = false
|
||||||
|
}
|
||||||
|
tasks.jar {
|
||||||
|
enabled = true
|
||||||
|
}
|
||||||
|
|
||||||
|
// cache-api/build.gradle.kts
|
||||||
|
// Kein Spring Boot Plugin, daher keine bootJar-Tasks
|
||||||
|
```
|
||||||
|
|
||||||
|
**Empfehlung**: Konsistenten Ansatz wählen und dokumentieren.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## ✅ Sehr Gute Architektur-Entscheidungen
|
||||||
|
|
||||||
|
### 1. **Konsequente API-Implementierung Trennung**
|
||||||
|
```
|
||||||
|
infrastructure/
|
||||||
|
cache/
|
||||||
|
cache-api/ # ✅ Interfaces
|
||||||
|
redis-cache/ # ✅ Implementierung
|
||||||
|
event-store/
|
||||||
|
event-store-api/ # ✅ Interfaces
|
||||||
|
redis-event-store/ # ✅ Implementierung
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. **Platform-Module für zentrale Abhängigkeiten**
|
||||||
|
```kotlin
|
||||||
|
implementation(platform(projects.platform.platformBom))
|
||||||
|
implementation(projects.platform.platformDependencies)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. **Bundle-basierte Dependencies**
|
||||||
|
```kotlin
|
||||||
|
implementation(libs.bundles.redis.cache)
|
||||||
|
implementation(libs.bundles.kafka.config)
|
||||||
|
implementation(libs.bundles.monitoring.client)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. **Qualifier für Bean-Konflikte**
|
||||||
|
```kotlin
|
||||||
|
@Bean
|
||||||
|
@ConditionalOnMissingBean(name = ["eventStoreRedisConnectionFactory"])
|
||||||
|
fun eventStoreRedisConnectionFactory(...)
|
||||||
|
|
||||||
|
@Qualifier("eventStoreRedisConnectionFactory")
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 📋 Zusammenfassung: Zu behebende Punkte
|
||||||
|
|
||||||
|
### 🔴 Kritisch (Breaking Issues):
|
||||||
|
1. **Auth-Service Consul-Registration** aktivieren oder Gateway-Route anpassen
|
||||||
|
2. **Gateway redis-event-store Dependency** klären/entfernen
|
||||||
|
|
||||||
|
### ⚠️ Wichtig (Inkonsistenzen):
|
||||||
|
3. **Auth-Server Monitoring** - `monitoring-client` verwenden für Konsistenz
|
||||||
|
4. **Redis-Module Dokumentation** - Gleichzeitige Nutzung dokumentieren
|
||||||
|
5. **Build-Script-Patterns** vereinheitlichen
|
||||||
|
|
||||||
|
### ℹ️ Optional (Verbesserungen):
|
||||||
|
6. Zentrale `application.yml` Properties dokumentieren
|
||||||
|
7. Integration-Tests für Redis-Modul-Kombinationen
|
||||||
|
8. OpenAPI/Swagger für auth-server hinzufügen (wie bei Gateway dokumentiert)
|
||||||
|
|
||||||

# Redis Cache Module
|
||||||
|
|
||||||
|
## Überblick
|
||||||
|
|
||||||
|
Dieses Modul stellt eine konkrete Implementierung der `cache-api` unter Verwendung von Redis als Caching-Backend bereit.
|
||||||
|
|
||||||
|
## Architektur
|
||||||
|
|
||||||
|
Das Modul folgt dem Provider-Pattern:
|
||||||
|
- **cache-api**: Provider-agnostische Interfaces (`CacheService`, `DistributedCache`)
|
||||||
|
- **redis-cache**: Redis-spezifische Implementierung
|
||||||
|
|
||||||
|
## Verwendung
|
||||||
|
|
||||||
|
### Dependency Hinzufügen
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
dependencies {
|
||||||
|
implementation(projects.infrastructure.cache.redisCache)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Konfiguration
|
||||||
|
|
||||||
|
Das Modul verwendet Spring Boot Auto-Configuration. Konfigurieren Sie Redis über `application.yml`:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
redis:
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
password: null # Optional
|
||||||
|
database: 0 # Default cache database
|
||||||
|
connectionTimeout: 2000
|
||||||
|
readTimeout: 2000
|
||||||
|
usePooling: true
|
||||||
|
maxPoolSize: 8
|
||||||
|
minPoolSize: 2
|
||||||
|
```
|
||||||
|
|
||||||
|
### Code-Beispiel
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
@Service
|
||||||
|
class MyService(private val cache: DistributedCache) {
|
||||||
|
|
||||||
|
suspend fun getData(key: String): MyData? {
|
||||||
|
return cache.get(key, MyData::class)
|
||||||
|
}
|
||||||
|
|
||||||
|
suspend fun saveData(key: String, data: MyData) {
|
||||||
|
cache.put(key, data, ttl = 1.hours)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- ✅ TTL-Unterstützung für Cache-Einträge
|
||||||
|
- ✅ Connection State Tracking
|
||||||
|
- ✅ Health Monitoring
|
||||||
|
- ✅ Jackson-basierte Serialisierung
|
||||||
|
- ✅ Connection Pooling mit Lettuce
|
||||||
|
- ✅ Kotlin Coroutines Support
|
||||||
|
|
||||||
|
## Beans
|
||||||
|
|
||||||
|
Das Modul registriert folgende Spring Beans:
|
||||||
|
|
||||||
|
- `redisConnectionFactory`: Standard Redis ConnectionFactory
|
||||||
|
- `redisTemplate`: RedisTemplate<String, ByteArray> für Cache-Operationen
|
||||||
|
- `cacheSerializer`: Jackson-basierter Serializer (kann überschrieben werden)
|
||||||
|
- `cacheConfiguration`: Standard Cache-Konfiguration (kann überschrieben werden)
|
||||||
|
|
||||||
|
## Gleichzeitige Verwendung mit redis-event-store
|
||||||
|
|
||||||
|
⚠️ **WICHTIG**: Wenn Sie sowohl `redis-cache` als auch `redis-event-store` im selben Service verwenden:
|
||||||
|
|
||||||
|
### Unterschiedliche Databases
|
||||||
|
|
||||||
|
Die Module verwenden **separate Redis Databases**, um Konflikte zu vermeiden:
|
||||||
|
|
||||||
|
- **redis-cache**: Database 0 (Standard)
|
||||||
|
- **redis-event-store**: Database 1 (konfigurierbar)
|
||||||
|
|
||||||
|
### Konfigurationsbeispiel
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Redis Cache Konfiguration
|
||||||
|
redis:
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
database: 0 # Cache verwendet Database 0
|
||||||
|
|
||||||
|
# Redis Event Store Konfiguration
|
||||||
|
redis:
|
||||||
|
event-store:
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
database: 1 # Event Store verwendet Database 1
|
||||||
|
```
|
||||||
|
|
||||||
|
### Bean-Namen
|
||||||
|
|
||||||
|
Die Module verwenden unterschiedliche Bean-Namen:
|
||||||
|
|
||||||
|
| Komponente | redis-cache | redis-event-store |
|
||||||
|
|------------|-------------|-------------------|
|
||||||
|
| ConnectionFactory | `redisConnectionFactory` | `eventStoreRedisConnectionFactory` |
|
||||||
|
| Template | `redisTemplate` | `eventStoreRedisTemplate` |
|
||||||
|
| Serializer | `cacheSerializer` | `eventSerializer` |
|
||||||
|
|
||||||
|
### Keine Konflikte
|
||||||
|
|
||||||
|
✅ Die Module sind so designed, dass sie **ohne Konflikte** gleichzeitig verwendet werden können:
|
||||||
|
- Separate ConnectionFactories mit `@Qualifier`
|
||||||
|
- Separate Property-Prefixes (`redis` vs `redis.event-store`)
|
||||||
|
- Unterschiedliche Database-Nummern
|
||||||
|
- Unterschiedliche Bean-Namen
|
||||||
|
|
||||||
|
## Serialisierung
|
||||||
|
|
||||||
|
Das Modul verwendet Jackson für die Serialisierung:
|
||||||
|
- Automatische Kotlin-Modul Integration
|
||||||
|
- Java 8 Date/Time Support
|
||||||
|
- Custom Serializer können via `@Bean` überschrieben werden
|
||||||
|
|
||||||
|
## Health Checks
|
||||||
|
|
||||||
|
Das Modul tracked automatisch den Redis-Verbindungsstatus:
|
||||||
|
- Connection State (CONNECTED, DISCONNECTED, CONNECTING)
|
||||||
|
- Connection State Listeners für Benachrichtigungen
|
||||||
|
- Automatische Reconnect-Versuche
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
- **Connection Pooling**: Wiederverwendbare Verbindungen via Lettuce
|
||||||
|
- **Non-blocking I/O**: Reaktive Operations mit Kotlin Coroutines
|
||||||
|
- **Optimierte Serialisierung**: Jackson-basiert mit Byte-Array-Caching
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Redis Verbindungsfehler
|
||||||
|
|
||||||
|
```
|
||||||
|
RedisConnectionFailureException: Unable to connect to Redis
|
||||||
|
```
|
||||||
|
|
||||||
|
**Lösung**: Überprüfen Sie Redis-Server und Netzwerk-Konfiguration.
|
||||||
|
|
||||||
|
### Serialisierungsfehler
|
||||||
|
|
||||||
|
```
|
||||||
|
SerializationException: Could not serialize object
|
||||||
|
```
|
||||||
|
|
||||||
|
**Lösung**: Stellen Sie sicher, dass Ihre Datenklassen mit Jackson serialisierbar sind (data classes, keine private Konstruktoren).
|
||||||
|
|
||||||
|
### Bean-Konflikte mit Event Store
|
||||||
|
|
||||||
|
Wenn Sie Fehler wie "Multiple beans of type RedisConnectionFactory" erhalten:
|
||||||
|
|
||||||
|
**Lösung**: Verwenden Sie `@Qualifier` Annotations oder stellen Sie sicher, dass Sie die neueste Version beider Module verwenden (Bean-Namen-Konflikte sind bereits behoben).

# Redis Event Store Module
|
||||||
|
|
||||||
|
## Überblick
|
||||||
|
|
||||||
|
Dieses Modul stellt eine konkrete Implementierung der `event-store-api` unter Verwendung von Redis Streams als Event-Store-Backend bereit.
|
||||||
|
|
||||||
|
## Architektur
|
||||||
|
|
||||||
|
Das Modul folgt dem Provider-Pattern:
|
||||||
|
- **event-store-api**: Provider-agnostische Interfaces (`EventStore`, `EventSerializer`)
|
||||||
|
- **redis-event-store**: Redis Streams-spezifische Implementierung
|
||||||
|
|
||||||
|
## Verwendung
|
||||||
|
|
||||||
|
### Dependency Hinzufügen
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
dependencies {
|
||||||
|
implementation(projects.infrastructure.eventStore.redisEventStore)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Konfiguration
|
||||||
|
|
||||||
|
Das Modul verwendet Spring Boot Auto-Configuration. Konfigurieren Sie Redis über `application.yml`:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
redis:
|
||||||
|
event-store:
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
password: null # Optional
|
||||||
|
database: 1 # Separate database for event store (default: 1)
|
||||||
|
connectionTimeout: 2000
|
||||||
|
readTimeout: 2000
|
||||||
|
usePooling: true
|
||||||
|
maxPoolSize: 8
|
||||||
|
minPoolSize: 2
|
||||||
|
consumerGroup: event-processors
|
||||||
|
consumerName: event-consumer
|
||||||
|
streamPrefix: "event-stream:"
|
||||||
|
allEventsStream: all-events
|
||||||
|
claimIdleTimeout: 60s
|
||||||
|
pollTimeout: 100ms
|
||||||
|
maxBatchSize: 100
|
||||||
|
createConsumerGroupIfNotExists: true
|
||||||
|
```
|
||||||
|
|
||||||
|
### Code-Beispiel
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
@Service
|
||||||
|
class MyEventService(
|
||||||
|
private val eventStore: EventStore,
|
||||||
|
private val eventConsumer: RedisEventConsumer
|
||||||
|
) {
|
||||||
|
|
||||||
|
// Event speichern
|
||||||
|
suspend fun saveEvent(aggregateId: Uuid, event: DomainEvent) {
|
||||||
|
eventStore.appendEvent(
|
||||||
|
aggregateId = aggregateId,
|
||||||
|
event = event,
|
||||||
|
expectedVersion = EventVersion.ANY
|
||||||
|
)
|
||||||
|
}
|
||||||
|
|
||||||
|
// Events abrufen
|
||||||
|
suspend fun loadEvents(aggregateId: Uuid): List<DomainEvent> {
|
||||||
|
return eventStore.loadEvents(aggregateId)
|
||||||
|
}
|
||||||
|
|
||||||
|
// Events konsumieren
|
||||||
|
fun startConsuming() {
|
||||||
|
eventConsumer.consumeEvents { event ->
|
||||||
|
println("Received event: $event")
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

|
|
||||||
|
## Redis Streams
|
||||||
|
|
||||||
|
Das Modul nutzt Redis Streams für Event Sourcing:
|
||||||
|
|
||||||
|
- **Stream pro Aggregate**: `event-stream:{aggregateId}`
|
||||||
|
- **All Events Stream**: `event-stream:all-events`
|
||||||
|
- **Consumer Groups**: Für parallele Verarbeitung
|
||||||
|
- **Message IDs**: Für Event-Ordering und Replay
|
||||||
|
|
||||||
|
## Beans
|
||||||
|
|
||||||
|
Das Modul registriert folgende Spring Beans:
|
||||||
|
|
||||||
|
- `eventStoreRedisConnectionFactory`: Separate Redis ConnectionFactory für Event Store
|
||||||
|
- `eventStoreRedisTemplate`: StringRedisTemplate für Event-Operationen
|
||||||
|
- `eventSerializer`: Jackson-basierter Event-Serializer
|
||||||
|
- `eventStore`: EventStore Implementierung
|
||||||
|
- `eventConsumer`: RedisEventConsumer für Event-Verarbeitung
|
||||||
|
|
||||||
|
## Gleichzeitige Verwendung mit redis-cache
|
||||||
|
|
||||||
|
⚠️ **WICHTIG**: Wenn Sie sowohl `redis-cache` als auch `redis-event-store` im selben Service verwenden:
|
||||||
|
|
||||||
|
### Unterschiedliche Databases
|
||||||
|
|
||||||
|
Die Module verwenden **separate Redis Databases**, um Konflikte zu vermeiden:
|
||||||
|
|
||||||
|
- **redis-cache**: Database 0 (Standard)
|
||||||
|
- **redis-event-store**: Database 1 (Standard, konfigurierbar)
|
||||||
|
|
||||||
|
### Konfigurationsbeispiel
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Beide Module in einer application.yml
|
||||||
|
redis:
|
||||||
|
# Cache Konfiguration
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
database: 0 # Cache verwendet Database 0
|
||||||
|
|
||||||
|
# Event Store Konfiguration (nested)
|
||||||
|
event-store:
|
||||||
|
host: localhost
|
||||||
|
port: 6379
|
||||||
|
database: 1 # Event Store verwendet Database 1
|
||||||
|
consumerGroup: event-processors
|
||||||
|
```
|
||||||
|
|
||||||
|
### Bean-Namen
|
||||||
|
|
||||||
|
Die Module verwenden unterschiedliche Bean-Namen zur Vermeidung von Konflikten:
|
||||||
|
|
||||||
|
| Komponente | redis-cache | redis-event-store |
|
||||||
|
|------------|-------------|-------------------|
|
||||||
|
| ConnectionFactory | `redisConnectionFactory` | `eventStoreRedisConnectionFactory` |
|
||||||
|
| Template | `redisTemplate` | `eventStoreRedisTemplate` |
|
||||||
|
| Serializer | `cacheSerializer` | `eventSerializer` |
|
||||||
|
|
||||||
|
### Keine Konflikte
|
||||||
|
|
||||||
|
✅ Die Module sind so designed, dass sie **ohne Konflikte** gleichzeitig verwendet werden können:
|
||||||
|
- **Separate ConnectionFactories** mit `@Qualifier` Annotations
|
||||||
|
- **Separate Property-Prefixes**: `redis` vs `redis.event-store`
|
||||||
|
- **Unterschiedliche Database-Nummern**: 0 vs 1
|
||||||
|
- **Unterschiedliche Bean-Namen**: Explizite Qualifier verhindern Kollisionen
|
||||||
|
|
||||||
|
## Event Versioning
|
||||||
|
|
||||||
|
Das Modul unterstützt Optimistic Locking:
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// Erwartete Version spezifizieren
|
||||||
|
eventStore.appendEvent(
|
||||||
|
aggregateId = aggregateId,
|
||||||
|
event = myEvent,
|
||||||
|
expectedVersion = EventVersion.of(5) // Erwartet Version 5
|
||||||
|
)
|
||||||
|
|
||||||
|
// Beliebige Version akzeptieren
|
||||||
|
eventStore.appendEvent(
|
||||||
|
aggregateId = aggregateId,
|
||||||
|
event = myEvent,
|
||||||
|
expectedVersion = EventVersion.ANY
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
Bei Version-Konflikten wird eine `ConcurrencyException` geworfen.
|
||||||
|
|
||||||
|
## Consumer Groups
|
||||||
|
|
||||||
|
Das Modul unterstützt Consumer Groups für parallele Event-Verarbeitung:
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// Consumer 1
|
||||||
|
eventConsumer.consumeEvents(
|
||||||
|
consumerName = "consumer-1"
|
||||||
|
) { event ->
|
||||||
|
// Verarbeite Event
|
||||||
|
processEvent(event)
|
||||||
|
}
|
||||||
|
|
||||||
|
// Consumer 2 (in der gleichen Consumer Group)
|
||||||
|
eventConsumer.consumeEvents(
|
||||||
|
consumerName = "consumer-2"
|
||||||
|
) { event ->
|
||||||
|
// Verarbeite Event parallel
|
||||||
|
processEvent(event)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Events werden automatisch auf verfügbare Consumer verteilt.
|
||||||
|
|
||||||
|
## Event Replay
|
||||||
|
|
||||||
|
Sie können Events von einem bestimmten Zeitpunkt oder Message-ID replaying:
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// Replay alle Events eines Aggregates
|
||||||
|
val events = eventStore.loadEvents(aggregateId)
|
||||||
|
|
||||||
|
// Replay Events ab einer bestimmten Version
|
||||||
|
val eventsFromVersion = eventStore.loadEvents(
|
||||||
|
aggregateId = aggregateId,
|
||||||
|
fromVersion = EventVersion.of(10)
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Serialisierung
|
||||||
|
|
||||||
|
Das Modul verwendet Jackson für Event-Serialisierung:
|
||||||
|
- Automatische Kotlin-Modul Integration
|
||||||
|
- Polymorphe Serialisierung für verschiedene Event-Typen
|
||||||
|
- Custom Serializer können via `@Bean` überschrieben werden
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
- **Connection Pooling**: Wiederverwendbare Verbindungen via Lettuce
|
||||||
|
- **Batch Processing**: Konfigurierbare Batch-Größe für Consumer
|
||||||
|
- **Non-blocking I/O**: Reaktive Operations mit Kotlin Coroutines
|
||||||
|
- **Stream-basiert**: Effiziente Event-Speicherung mit Redis Streams
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Redis Verbindungsfehler
|
||||||
|
|
||||||
|
```
|
||||||
|
RedisConnectionFailureException: Unable to connect to Redis
|
||||||
|
```
|
||||||
|
|
||||||
|
**Lösung**: Überprüfen Sie Redis-Server und Netzwerk-Konfiguration. Stellen Sie sicher, dass Redis Streams unterstützt werden (Redis 5.0+).
|
||||||
|
|
||||||
|
### Concurrency Exception
|
||||||
|
|
||||||
|
```
|
||||||
|
ConcurrencyException: Expected version X but found Y
|
||||||
|
```
|
||||||
|
|
||||||
|
**Lösung**: Dies ist normales Verhalten bei Optimistic Locking. Implementieren Sie Retry-Logik oder verwenden Sie `EventVersion.ANY`.
|
||||||
|
|
||||||
|
### Consumer Group Fehler
|
||||||
|
|
||||||
|
```
|
||||||
|
Consumer group already exists
|
||||||
|
```
|
||||||
|
|
||||||
|
**Lösung**: Setzen Sie `createConsumerGroupIfNotExists: true` in der Konfiguration oder löschen Sie die Consumer Group manuell.
|
||||||
|
|
||||||
|
### Bean-Konflikte mit Cache
|
||||||
|
|
||||||
|
Wenn Sie Fehler wie "Multiple beans of type RedisConnectionFactory" erhalten:
|
||||||
|
|
||||||
|
**Lösung**: Die Module verwenden bereits unterschiedliche Bean-Namen mit `@Qualifier`. Stellen Sie sicher, dass Sie beide Module korrekt konfiguriert haben (siehe Abschnitt "Gleichzeitige Verwendung").
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
1. **Separate Databases**: Verwenden Sie immer separate Redis Databases für Cache und Event Store
|
||||||
|
2. **Event Versioning**: Verwenden Sie Optimistic Locking für kritische Aggregates
|
||||||
|
3. **Consumer Groups**: Nutzen Sie Consumer Groups für horizontale Skalierung
|
||||||
|
4. **Error Handling**: Implementieren Sie Retry-Logik für transiente Fehler
|
||||||
|
5. **Monitoring**: Überwachen Sie Stream-Größen und Consumer Lag

|
### Kritische Variablen für Produktion
|
||||||
|
|
||||||
|
| Variable | Beschreibung | Default |
|
||||||
|
|----------|--------------|---------|
|
||||||
|
| `GATEWAY_PORT` | Gateway Port | 8081 |
|
||||||
|
| `CONSUL_HOST` | Consul Server | localhost |
|
||||||
|

|
---
|
||||||
|
|
||||||
|
## Profile-spezifische Konfiguration
|
||||||
|
|
||||||
|
Das Gateway unterstützt verschiedene Spring Profile:
|
||||||
|
|
||||||
|
### dev (Development)
|
||||||
|
- Detailliertes Logging
|
||||||
|
- Alle Monitoring-Endpunkte verfügbar
|
||||||
|
- Tracing optional
|
||||||
|
|
||||||
|
### test
|
||||||
|
- Reduziertes Logging
|
||||||
|
- Test-spezifische Timeouts
|
||||||
|
- In-Memory Services optional
|
||||||
|
|
||||||
|
### prod (Production)
|
||||||
|
- Production-ready Logging
|
||||||
|
- Sichere Credentials erforderlich
|
||||||
|
- Tracing empfohlen
|
||||||
|
- Rate Limiting aktiviert
|
||||||
|
|
||||||
|
**Beispiel für profile-spezifische Datei:**
|
||||||
|
```yaml
|
||||||
|
# application-prod.yml
|
||||||
|
spring:
|
||||||
|
security:
|
||||||
|
user:
|
||||||
|
name: ${GATEWAY_ADMIN_USER} # Muss gesetzt sein!
|
||||||
|
password: ${GATEWAY_ADMIN_PASSWORD} # Muss gesetzt sein!
|
||||||
|
|
||||||
|
management:
|
||||||
|
tracing:
|
||||||
|
enabled: true
|
||||||
|
sampling:
|
||||||
|
probability: 0.1 # 10% Sampling in Production
|
||||||
|
|
||||||
|
logging:
|
||||||
|
level:
|
||||||
|
at.mocode.infrastructure.gateway: INFO # Weniger Logs
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
1. **Umgebungsvariablen verwenden**: Nie Credentials in application.yml hardcoden
|
||||||
|
2. **Profile nutzen**: Separate Konfigurationen für dev/test/prod
|
||||||
|
3. **Health Checks aktivieren**: Für Consul und Kubernetes
|
||||||
|
4. **Tracing in Production**: Mindestens 10% Sampling
|
||||||
|
5. **Monitoring exportieren**: Prometheus-Endpunkt für Grafana
|
||||||
|
6. **Circuit Breaker tunen**: An Service-Charakteristiken anpassen
|
||||||
|
7. **CORS restriktiv**: Nur benötigte Origins erlauben
|
||||||
|
8. **Log Rotation**: Verhindert volle Festplatten
|
||||||

|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Gateway startet nicht
|
||||||
|
- ✅ Prüfen: Consul erreichbar?
|
||||||
|
- ✅ Prüfen: Port 8081 frei?
|
||||||
|
- ✅ Prüfen: Keycloak erreichbar? (Optional)
|
||||||
|
|
||||||
|
### Service nicht erreichbar
|
||||||
|
- ✅ Prüfen: Service in Consul registriert?
|
||||||
|
- ✅ Prüfen: Circuit Breaker offen?
|
||||||
|
- ✅ Prüfen: Health Check erfolgreich?
|
||||||
|
|
||||||
|
### CORS-Fehler
|
||||||
|
- ✅ Prüfen: Origin in allowedOriginPatterns?
|
||||||
|
- ✅ Prüfen: Methode in allowedMethods?
|
||||||
|
- ✅ Prüfen: allowCredentials korrekt?
|
||||||
|
|
||||||
|
### Hohe Latenz
|
||||||
|
- ✅ Prüfen: response-timeout zu hoch?
|
||||||
|
- ✅ Prüfen: Backend-Services langsam?
|
||||||
|
- ✅ Prüfen: Connection Pool ausgeschöpft?
|
