如何将JSON Patch与Spring Data REST结合使用？

@RestController
@RequestMapping("/api")
public class UserController {
    private final UserRepository userRepository;

    public UserController(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @PatchMapping("/users/{id}")
    public ResponseEntity<User> updateUser(@PathVariable Long id, @RequestBody JsonNode patch) {
        Optional<User> optionalUser = userRepository.findById(id);
        if (optionalUser.isPresent()) {
            User user = optionalUser.get();
            try {
                JsonNode patchedUser = JsonPatch.apply(patch, user);
                User updatedUser = userRepository.save(patchedUser);
                return ResponseEntity.ok(updatedUser);
            } catch (JsonPatchException | JsonProcessingException e) {
                return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
            }
        } else {
            return ResponseEntity.notFound().build();
        }
    }
}
