我想測試我的 Spring 控制器，它有輸入 json 和多部分文件，但是即使該功能有效，我也無法讓測試工作我嘗試使用 MockMvcRequestBuilders.fileUpload 但測試總是得到 405控制器： @PutMapping(value = "/upload", consumes = {"multipart/form-data"})  public BaseResponse<SomeModel> updateSomeModelContent(      @ApiIgnore @Valid @ModelAttribute MandatoryRequest mandatoryRequest,      @PathVariable("id") String id,      @RequestParam("file") MultipartFile file,      @RequestParam("json") String json) throws IOException {    final CommonSomeModelRequest request = JSONHelper.convertJsonInStringToObject(json, CommonSomeModelRequest.class);    return makeResponse(someModelSer.updateContent(id, request, mandatoryRequest, file));  }考試：  @Test  public void updateCountryContentSuccessTest() throws Exception {    MockMultipartFile file1 = new MockMultipartFile("file", "filename-1.jpeg", "image/jpeg", "some-image".getBytes());    MockMultipartFile file2 = new MockMultipartFile("json", "", "application/json","{\"exampleAttr\": \"someValue\"}".getBytes());    when(this.someModelService        .updateContent(id, request, MANDATORY_REQUEST, file1))        .thenReturn(someModelUpdatedContent);    MockHttpServletRequestBuilder builder = MockMvcRequestBuilders        .fileUpload("/upload/{id}", id)        .file(file1)        .file(file2)        .requestAttr("mandatory", MANDATORY_REQUEST);    this.mockMvc.perform(builder)        .andExpect(status().isOk());    verify(this.someModelService)        .updateContent(id, request, MANDATORY_REQUEST, file1);  }結果狀態一直是405，不知道怎么變成200
