insert

Service

Antes

@Transactional
public UserDTO insert(UserDTO dto) {
    User entity = new User();
    copyDtoToEntity(dto, entity);
    entity = repository.save(entity);
    return new UserDTO(entity);
}

Depois

public Mono<UserDTO> insert(UserDTO dto) {
    User entity = new User();
    copyDtoToEntity(dto, entity);
    return repository.save(entity).map(UserDTO::new);
}

Controller

Passamos um URIComponentsBuilder para inserir no created.

Antes

@PostMapping
public ResponseEntity<UserDTO> insert(@RequestBody UserDTO dto) {
    dto = service.insert(dto);
    URI uri = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}").buildAndExpand(dto.getId()).toUri();
    return ResponseEntity.created(uri).body(dto);
}

Depois

@PostMapping
public Mono<ResponseEntity<UserDTO>> insert(@RequestBody UserDTO userDTO,
												UriComponentsBuilder builder) {
    return service.insert(userDTO).map(userDTO1 ->
            ResponseEntity.created(builder.path("/users/{id}").buildAndExpand(userDTO1.getId()).toUri())
                    .body(userDTO1));
}
