Question

我写了一些与使用spring上传文件相关的代码，它运行正常，现在我正在为此编写集成测试用例，但我面临一些问题我的控制器方法，

@RequestMapping(value = "/{attributeName}/upload", method = RequestMethod.POST)
@ResponseBody
public Result uploadCompany(HttpServletRequest request,
        @RequestParam MultipartFile file, @PathVariable String attributeName,
        @RequestParam long dateKey)
        throws IOException, PromotionException {
    some code
}

测试用例

@Test
public void shouldReturnTrueStatusWhenUploadCompany() throws Exception {
    MockMultipartFile file = new MockMultipartFile("company_upload", "company_upload.csv",
            MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));
    mockMvc.perform(
            MockMvcRequestBuilders.fileUpload(
                    PROMOTION + StringUtils.replace(ATTRIBUTE_NAME, "{attributeName}", "COMPANY") + "/upload")
                    .file(file).param("dateKey", "852017")  .contentType(MediaType.MULTIPART_FORM_DATA)
                    .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());

}

但我得到了

2017-05-09 13:42:42,506 ERROR [Test worker] INTERNAL_SERVER_ERROR: 
org.springframework.web.bind.MissingServletRequestParameterException: Required MultipartFile parameter 'file' is not present

我哪里错了？

Answer 1

更改行

git pull

到

 MockMultipartFile file = new MockMultipartFile("company_upload", "company_upload.csv",
                    MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));

或将您的控制器方法声明更改为此类

 MockMultipartFile file = new MockMultipartFile("file", "company_upload.csv",
                    MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));

集成测试用例和文件上传
