＆＃34;请求方法＆＃39; POST＆＃39;不支持＆＃34;。弹簧

Question

当我尝试POST方法时，我总是收到以下错误：

  

{＆＃34; status＆＃34;：405   ＆＃34;错误＆＃34;：＆＃34;方法不允许＆＃34;   ＆＃34;例外＆＃34;：＆＃34; org.springframework.web.HttpRequestMethodNotSupportedException＆＃34;   ＆＃34;消息＆＃34;：＆＃34;请求方法＆＃39; POST＆＃39;不支持＆＃34;   ＆＃34;路径＆＃34;：＆＃34; / api / items＆＃34; }

@RepositoryRestController
@RequestMapping("/items")
public class ItemController {

    private static final Logger LOGGER = LoggerFactory.getLogger(ItemController.class);
    private final ItemService service;

    @Autowired
    public ItemController(ItemService service) {
        this.service = service;
    }

    @RequestMapping(method = RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    ItemDto create(@RequestBody @Valid ItemDto item) {
        LOGGER.debug("Creating item={}", item);
        return service.create(item);
    }    
}

@RepositoryRestResource()
public interface ItemRepository extends MongoRepository<Item, String> {}

@Service
public class ItemServiceImpl implements ItemService {

    private static final Logger LOGGER = LoggerFactory.getLogger(ItemServiceImpl.class);
    private final ItemRepository itemRepository;

    @Autowired
    public ItemServiceImpl(ItemRepository itemRepository) {
        this.itemRepository = itemRepository;
    }
    @Override
    public ItemDto create(ItemDto item) {
        Date date = new Date(System.currentTimeMillis());
        LOGGER.debug("Creating new item={}, date={}", item, date);

        Item persisted = Item.getItemBuilder(item.getTitle(), item.getPrice(), item.getDescription())
                .withCategory(item.getCategory())
                .withOwner(item.getOwner())
                .withPhotos(item.getPhotoURLs())
                .withState(item.getState())
                .withDate(date)
                .build();
        itemRepository.save(persisted);
        return convertToDto(persisted);
    }

你知道为什么以及如何解决它吗？提前致谢
