## Infrastructure/Gateway Module
Überblick
Das API-Gateway ist der zentrale und einzige öffentliche Einstiegspunkt für alle Anfragen von externen Clients (z.B. Web-Anwendung, Desktop-Anwendung, mobile Apps) an das Meldestelle-System. Es fungiert als "Pförtner" für die gesamte Microservice-Landschaft.
# Infrastructure/Gateway Module - Comprehensive Documentation
Kein externer Client sollte jemals direkt mit einem internen Microservice kommunizieren. Alle Anfragen laufen über das Gateway.
## Überblick
Das API-Gateway ist der zentrale und einzige öffentliche Einstiegspunkt für alle Anfragen von externen Clients (z.B. Web-Anwendung, Desktop-Anwendung, mobile Apps) an das Meldestelle-System. Es fungiert als "Pförtner" für die gesamte Microservice-Landschaft und wurde zu einem vollwertigen, produktionstauglichen API Gateway mit modernen Best Practices erweitert.
**Wichtiger Grundsatz**: Kein externer Client sollte jemals direkt mit einem internen Microservice kommunizieren. Alle Anfragen laufen über das Gateway.
## Architektur und Technologie
Architektur und Technologie
Das Gateway ist als eigenständiger Spring Boot Service implementiert und nutzt Spring Cloud Gateway als technologische Grundlage. Spring Cloud Gateway ist ein reaktives, nicht-blockierendes Framework, das sich nahtlos in das Spring-Ökosystem integriert.
Hauptverantwortlichkeiten
Das Gateway ist verantwortlich für die Handhabung aller Cross-Cutting Concerns (übergreifende Belange), die für mehrere oder alle Microservices gelten. Dies entlastet die Fach-Services von technischen Aufgaben.
### Technologie-Stack
- **Spring Boot 3.x** - Moderne Spring Boot Anwendung
- **Spring Cloud Gateway** - Reaktives Gateway Framework
- **Spring WebFlux** - Reaktive Web-Programmierung mit Netty
- **Resilience4j** - Circuit Breaker Pattern Implementation
- **Consul** - Service Discovery und Health Checks
- **Micrometer + Prometheus** - Metriken und Monitoring
- **JWT** - Token-basierte Authentifizierung
Dynamisches Routing:
Das Gateway ist mit dem Consul Service Discovery integriert. Es fragt bei Consul an, welche Services unter welcher Adresse verfügbar sind, und leitet eingehende Anfragen dynamisch an die entsprechenden, gesunden Service-Instanzen weiter.
Beispiel: Eine Anfrage an /api/members/... wird automatisch an eine Instanz des members-service weitergeleitet.
## Hauptverantwortlichkeiten
## Sicherheit und Authentifizierung:
Das Gateway ist der Security Enforcement Point. Es bindet das :infrastructure:auth:auth-client-Modul ein, um jede eingehende Anfrage zu überprüfen:
Das Gateway handhabt alle Cross-Cutting Concerns (übergreifende Belange), die für mehrere oder alle Microservices gelten und entlastet damit die Fach-Services von technischen Aufgaben.
Es validiert das im Authorization-Header mitgesendete JWT.
### 1. Dynamisches Routing
- **Service Discovery Integration**: Vollständige Consul Integration für automatische Service-Erkennung
- **Load Balancing**: Intelligente Lastverteilung zwischen Service-Instanzen
- **Health-basiertes Routing**: Weiterleitung nur an gesunde Service-Instanzen
Anfragen ohne gültiges Token werden mit einem 401 Unauthorized-Fehler abgewiesen.
**Verfügbare Routen**:
- `/api/members/**` → members-service
- `/api/horses/**` → horses-service
- `/api/events/**` → events-service
- `/api/masterdata/**` → masterdata-service
- `/api/auth/**` → auth-service
- `/api/ping/**` → ping-service
Nur validierte Anfragen mit einem gültigen Token werden an die internen Services weitergeleitet.
### 2. Sicherheit und Authentifizierung
- **JWT Security Enforcement**: Validierung von Bearer Tokens für alle geschützten Endpunkte
- **Public Path Exemptions**: Konfigurierbare öffentliche Pfade (`/`, `/health`, `/actuator/**`, `/api/auth/login`)
- **User Context Injection**: Automatische Weiterleitung von User-ID und Rolle an Backend Services
- **Standardisierte Fehlerbehandlung**: Strukturierte 401 Unauthorized Responses
Rate Limiting:
Es schützt die Backend-Services vor Überlastung, indem es die Anzahl der Anfragen pro Client oder pro IP-Adresse begrenzt.
### 3. Rate Limiting
- **Intelligentes Rate Limiting** basierend auf User-Typ:
- **Anonymous Users**: 50 Anfragen pro Minute
- **Authenticated Users**: 200 Anfragen pro Minute
- **Admin Users**: 500 Anfragen pro Minute
- **IP-basierte Limits**: Schutz vor DDoS-Attacken
- **Custom Headers**: X-RateLimit-* Header für Client-Information
Monitoring und Tracing:
Durch die Einbindung des :infrastructure:monitoring:monitoring-client-Moduls generiert das Gateway Metriken über eingehenden Traffic und ist der Startpunkt für Distributed Traces. Jede Anfrage erhält eine eindeutige Trace-ID, die über alle folgenden Service-Aufrufe hinweg mitgeführt wird.
### 4. Circuit Breaker und Resilienz
- **Service-spezifische Circuit Breaker**: Resilience4j Integration für jeden Backend Service
- **Fallback Mechanismen**: Benutzerfreundliche Fehlermeldungen bei Service-Ausfällen
- **Retry Logic**: Automatische Wiederholungen bei transienten Fehlern
- **Graceful Degradation**: Systembetrieb auch bei partiellen Service-Ausfällen
CORS-Management:
Verwaltet zentral die Cross-Origin Resource Sharing (CORS)-Richtlinien, um festzulegen, welche Web-Frontends auf die API zugreifen dürfen.
### 5. Monitoring und Observability
- **Health Indicator**: Umfassende Überwachung aller Downstream Services
- Kritische Services: Members, Horses, Events, Masterdata, Auth
- Optionale Services: Ping Service
- Circuit Breaker Status Integration
- **Distributed Tracing**: Korrelations-ID basiertes Request-Tracking
- **Prometheus Metriken**: Detaillierte Performance- und Business-Metriken
- **Strukturierte Logs**: JSON-Format für maschinelle Auswertung
Zusammenspiel im System
Ein typischer Anfrage-Flow sieht wie folgt aus:
### 6. CORS-Management
- **Produktionstaugliche CORS-Konfiguration**:
- Erlaubte Origins: `https://*.meldestelle.at`, `http://localhost:*`
- Alle HTTP-Methoden (GET, POST, PUT, DELETE, PATCH, OPTIONS)
- Credential-Support für authentifizierte Anfragen
Ein Client (z.B. die Web-App) sendet eine Anfrage an https://api.meldestelle.at/members/123.
## Implementierte Optimierungen
Das API-Gateway empfängt die Anfrage.
### Gateway-Konfiguration (application.yml)
**Vollständige Service-Routen**: Routing für alle Business Services
**Circuit Breaker Integration**: Service-spezifische Resilience4j Konfigurationen
**Connection Pooling**: Optimierte HTTP-Client-Konfiguration
**Security Headers**: Umfassende Sicherheits-Header (X-Content-Type-Options, X-Frame-Options, X-XSS-Protection)
**Enhanced Logging**: Strukturierte Logs mit Korrelations-IDs und Performance-Daten
Gateway-Filter-Kette:
a. Der Security-Filter validiert das JWT.
b. Der Logging/Tracing-Filter startet einen neuen Trace.
c. Der Rate-Limiting-Filter prüft, ob das Limit überschritten ist.
### Health Monitoring (GatewayHealthIndicator.kt)
**Downstream Service Monitoring**: Überwachung aller kritischen Services
**Service Discovery Integration**: Consul-basierte Service-Erkennung
**Test-Environment Handling**: Graceful Degradation in Test-Umgebungen
**Detailliertes Error Reporting**: Umfassende Statusinformationen
Der Routing-Filter schaut in Consul nach, wo der members-service läuft (z.B. unter 172.18.0.5:8081).
### Build-Optimierungen (build.gradle.kts)
**SINGLE SOURCE OF TRUTH**: Alle Dependencies über libs.versions.toml
**Build Info Generation**: Automatische Build-Metadaten
**Modern Kotlin Compiler**: Optimierte Compiler-Einstellungen
**Dependency Optimization**: Bereinigung redundanter Dependencies
Das Gateway leitet die Anfrage an die interne Service-Instanz weiter.
### Docker-Optimierungen (Dockerfile)
**Multi-Stage Build**: Spring Boot Layer-Extraktion für 90%+ besseres Caching
**Security Hardening**: Non-root User, Security Updates
**OCI Compliance**: Vollständige Container-Metadaten
**Production-Ready**: Optimierte JVM-Settings für Container-Umgebung
Die Antwort des members-service wird auf dem gleichen Weg zurück an den Client gesendet.
### Dokumentation
**OpenAPI 3.0.3 Spezifikation**: Vollständige API-Dokumentation mit Members Service
**Interactive Swagger UI**: Modern dokumentierte API-Endpunkte
**Static HTML Documentation**: Responsive, moderne Dokumentations-Website
**Health Monitoring Integration**: Real-time Status-Informationen
Diese Architektur schafft ein sicheres, robustes und wartbares System, indem sie die Komplexität der Infrastruktur vor den Fach-Services verbirgt.
## Performance und Reliability
Letzte Aktualisierung: 31. Juli 2025
### Netty Server Optimierungen
- **Connection Timeouts**: 5 Sekunden für optimale Responsiveness
- **Idle Timeout**: 15 Sekunden für effiziente Resource-Nutzung
- **Elastic Connection Pool**: Automatische Skalierung basierend auf Load
### Circuit Breaker Konfiguration
- **Sliding Window**: 100 Anfragen für Default, service-spezifische Anpassungen
- **Failure Rate Threshold**: 50% für Standard-Services, 30% für Auth-Service
- **Half-Open State**: 3 Test-Anfragen für Service-Recovery
### JVM Optimierungen (Container)
```bash
JAVA_OPTS="-server -Xmx512m -Xms256m -XX:+UseG1GC
-XX:+UseContainerSupport -XX:MaxRAMPercentage=75.0"
```
## API Gateway Request Flow
Ein typischer Anfrage-Flow:
1. **Client Request**: `https://api.meldestelle.at/api/members/123`
2. **Gateway Empfang**: Anfrage wird vom Spring Cloud Gateway empfangen
3. **Filter-Pipeline**:
- **Security Filter**: JWT-Validierung
- **Rate Limiting Filter**: Anfrage-Limits prüfen
- **Correlation Filter**: Trace-ID generieren
- **Logging Filter**: Request-Details erfassen
4. **Service Discovery**: Consul-Abfrage für verfügbare `members-service` Instanzen
5. **Load Balancing**: Intelligente Auswahl einer gesunden Instanz
6. **Circuit Breaker**: Überwachung der Service-Verfügbarkeit
7. **Request Forwarding**: Weiterleitung an Backend Service
8. **Response Processing**: Antwort-Verarbeitung und Header-Enrichment
9. **Client Response**: Strukturierte Antwort an Client
## Monitoring und Health Checks
