Spring Service Scaffold
Generate a $ARGUMENTSService with:
@Service annotation- Constructor injection of
$ARGUMENTSRepository (no field @Autowired)
- CRUD methods:
findAll(), findById(id), create(request), update(id, request), delete(id)
- Domain exceptions (e.g.,
EntityNotFoundException) thrown for missing-by-id; let @ControllerAdvice translate to HTTP if present
- SLF4J logging at meaningful boundaries — entry on writes, warn on validation rejection, debug on reads
- Unit tests using JUnit 5 + Mockito, with
@MockitoBean and @MockitoSpyBean where appropriate
- Use modern Java idioms (records for DTOs, pattern matching,
var where readable)
Constraints
- Match the existing project package layout
- Don't introduce
Lombok if the project doesn't already use it
- If the project uses MapStruct, generate a mapper interface; otherwise, write the mapping inline
- Tests should cover happy path, not-found, and at least one validation/edge case per write method
Usage: /spring-service User → UserService, UserServiceTest
