|
|
|
|

2. `api-gateway/src/main/kotlin/at/mocode/gateway/Application.kt` - Integrated OpenAPI configuration
|
|
|
|
## 🚀 How to Use
|
|
|
|
### 1. OpenAPI/Swagger
|
|
```bash
|
|
# Start the API Gateway
|
|
./gradlew :api-gateway:run
|
|
|
|
# Access Swagger UI
|
|
open http://localhost:8080/swagger
|
|
```
|
|
|
|
### 2. Postman Collection
|
|
1. Import `docs/postman/Meldestelle_API_Collection.json` into Postman
|
|
2. Set `baseUrl` variable to `http://localhost:8080`
|
|
3. Use the collection to test all API endpoints
|
|
4. Authentication tokens are automatically managed
|
|
|
|
### 3. API Tests
|
|
```bash
|
|
# Run API tests (when compilation issues are resolved)
|
|
./gradlew :api-gateway:jvmTest
|
|
```
|
|
|
|
