- 控制器在與我的其他控制器沿頂層，所以春天應該能夠找到它
- 的應用類標註有
@ComponentScan(basePackageClasses = MatchUpdateController.class)嘗試，並確保它位於它
相關的文件：
MatchUpdateRepository：
@RepositoryRestResource(collectionResourceRel = "updates", path = "updates")
public interface MatchUpdateRepository extends MongoRepository<MatchUpdate, String>, MatchUpdateRepositoryCustom {
List<MatchUpdate> findByReceiverId(@Param("id") String id);
}
MatchUpdateController：
@RepositoryRestController
public class MatchUpdateController {
private final MatchUpdateRepository repository;
@Autowired
public MatchUpdateController(MatchUpdateRepository repo) {
repository = repo;
}
@RequestMapping(value = "/updates", method = RequestMethod.POST)
public ResponseEntity<?> create(@RequestBody MatchUpdate update, UriComponentsBuilder builder,
@RequestHeader(value= HttpHeaders.AUTHORIZATION) String senderId) {
if (senderId == null) {

} else {
