Spring Service Scaffold
Generate a $ARGUMENTSService with:
@Serviceannotation- 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@ControllerAdvicetranslate 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
@MockitoBeanand@MockitoSpyBeanwhere appropriate - Use modern Java idioms (records for DTOs, pattern matching,
varwhere readable)
Constraints
- Match the existing project package layout
- Don't introduce
Lombokif 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
