Spring Boot Endpoint

Create a new REST endpoint that matches the project's existing structure.

Steps

Inspect first. Read the codebase to learn its conventions: package layout, controller/service style, DTO/mapper pattern, error handling, and validation approach. Match them — do not introduce a new pattern.
Build the layers:
- Controller — thin. Map request → service call → response. Correct HTTP verb + status code (201 for create, 204 for delete). @Valid on request bodies.
- Service — the business logic. Put @Transactional on write operations.
- DTOs — separate request and response types (records preferred). Never expose entities directly.
- Validation — bean-validation annotations (@NotNull, @Size, …) on the request DTO.
Return errors through the project's existing exception handler — don't add a new one.

Rules

Constructor injection, never field injection.
Keep controllers free of business logic.
Add only what the endpoint needs — nothing speculative.
If the project has a mapper (MapStruct, manual), use it; don't hand-roll a new style.
