POST405（不允许的方法）

Question

我正在使用AngularJS从我的控制器发送POST请求，我收到此错误：

  

不支持POST

JS函数如下：

  addUserDetails: function(addUser) {
      alert("M into add user function in service");
      return restClientTemplate.execute({
          method: 'POST',
          url: 'json/user-add',
          data: addUser
      });
  }

我的Java Spring Controller如下：

@Controller
public class AddUserController {

    @Resource
    private Settings settings;

    @Resource
    private RestOperations rest;

    private static final String ORGANIZATION_URL_KEY = "configuration.organization.service.endpointUrl";
    private static final String ORG_PRODUCT_LIST_URL_KEY = "configuration.org.product.list.service.endpointUrl";

    @RequestMapping(value = "/json/user-add", method = RequestMethod.POST, produces = "application/json")
    public ServiceResponse addOrganization(@RequestBody SaveOrganizationForm request) {  
        System.out.println("M into controllerrrr");

        ObjectMapper objectMapper = new ObjectMapper();
        ObjectNode requestBody = objectMapper.createObjectNode();
        populateRequestObject(request, objectMapper, requestBody);

        String url = MessageUtil.format(settings.getString(ORGANIZATION_URL_KEY) + "/s2");

        ServiceResponse response = rest
            .exchange(url, HttpMethod.POST, new HttpEntity<>(requestBody), ServiceResponse.class).getBody();

        return response;
    }
