How to add a file and body to MockMvc?

问题

使用Spring Boot 2和Spring MVC。我试图使用mockMvc测试我的REST控制器。

  1. @PostMapping(
  2.     value = "/attachment")
  3. public ResponseEntity attachment(MultipartHttpServletRequest file, @RequestBody DocumentRequest body) {
  5.     Document document;
  7.     try {
  9.         document = documentService.process(file.getFile("file"), body);
  11.     } catch (IOException | NullPointerException e) {
  13.         return ResponseEntity.badRequest().body(e.getMessage());
  15.     }
  17.     return ResponseEntity.accepted().body(DocumentUploadSuccess.of(
  18.             document.getId(),
  19.             "Document Uploaded",
  20.             LocalDateTime.now()
  21.     ));
  23. }

我可以成功地在测试中附加文件，但现在我添加了一个请求体，我不能同时接收附加的文件。

  1. @Test
  2. @DisplayName("Upload Document")
  3. public void testController() throws Exception {
  5.     byte[] attachedfile = IOUtils.resourceToByteArray("/request/document-text.txt");
  7.     MockMultipartFile mockMultipartFile = new MockMultipartFile("file", "",
  8.             "text/plain", attachedfile);
  10.     DocumentRequest documentRequest = new DocumentRequest();
  11.     documentRequest.setApplicationId("_APP_ID");
  13.     MockHttpServletRequestBuilder builder =
  14.             MockMvcRequestBuilders
  15.                     .fileUpload("/attachment")
  16.                     .file(mockMultipartFile)
  17.                     .content(objectMapper.writeValueAsString(documentRequest));
  19.     MvcResult result = mockMvc.perform(builder).andExpect(MockMvcResultMatchers.status().isAccepted())
  20.             .andDo(MockMvcResultHandlers.print()).andReturn();
  22.     JsonNode response = objectMapper.readTree(result.getResponse().getContentAsString());
  24.     String id = response.get("id").asText();
  26.     Assert.assertTrue(documentRepository.findById(id).isPresent());
  28. }

我得到了415状态错误。

  1. java.lang.AssertionError: Status expected:<202> but was:<415>
  2. Expected :202
  3. Actual   :415

我该如何修复这个问题？

Using Spring boot 2 and Spring mvc. I am trying to test my rest controller using mockMvc

  1.     @PostMapping(
  2.         value = &quot;/attachment&quot;)
  3. public ResponseEntity attachment(MultipartHttpServletRequest file, @RequestBody DocumentRequest body) {
  4.     
  5.     Document document;
  6.     
  7.     try {
  8.         
  9.         document = documentService.process(file.getFile(&quot;file&quot;), body);
  10.         
  11.     } catch (IOException | NullPointerException e) {
  12.         
  13.         return ResponseEntity.badRequest().body(e.getMessage());
  14.         
  15.     }
  16.     
  17.     return ResponseEntity.accepted().body(DocumentUploadSuccess.of(
  18.             document.getId(),
  19.             &quot;Document Uploaded&quot;,
  20.             LocalDateTime.now()
  21.     ));
  22.     
  23. }

I could attach the file successfully on my test but know I added a body and I can't receive both attached

  1.     @Test
  2. @DisplayName(&quot;Upload Document&quot;)
  3. public void testController() throws Exception {
  4.     
  5.     byte[] attachedfile = IOUtils.resourceToByteArray(&quot;/request/document-text.txt&quot;);
  6.     
  7.     MockMultipartFile mockMultipartFile = new MockMultipartFile(&quot;file&quot;, &quot;&quot;,
  8.             &quot;text/plain&quot;, attachedfile);
  9.     
  10.     
  11.     DocumentRequest documentRequest = new DocumentRequest();
  12.     documentRequest.setApplicationId(&quot;_APP_ID&quot;);
  13.     
  14.     MockHttpServletRequestBuilder builder =
  15.             MockMvcRequestBuilders
  16.                     .fileUpload(&quot;/attachment&quot;)
  17.                     .file(mockMultipartFile)
  18.                     .content(objectMapper.writeValueAsString(documentRequest));
  19.     
  20.     MvcResult result = mockMvc.perform(builder).andExpect(MockMvcResultMatchers.status().isAccepted())
  21.             .andDo(MockMvcResultHandlers.print()).andReturn();
  22.     
  23.     JsonNode response = objectMapper.readTree(result.getResponse().getContentAsString());
  24.     
  25.     String id = response.get(&quot;id&quot;).asText();
  26.     
  27.     Assert.assertTrue(documentRepository.findById(id).isPresent());
  28.     
  29. }

I got 415 status error

  1. java.lang.AssertionError: Status expected:&lt;202&gt; but was:&lt;415&gt;
  2. Expected :202
  3. Actual   :415

How could I fix it?

收到状态码 415：不支持的媒体类型。

您需要修改请求的contentType()，使其与控制器所接受的内容类型一致。
如果您的控制器接受 application/json：

  1.         MockHttpServletRequestBuilder builder =
  2.                 MockMvcRequestBuilders
  3.                         .multipart("/attachment")
  4.                         .file(mockMultipartFile)
  5.                         .content(objectMapper.writeValueAsString(documentRequest))
  6.                         .contentType(MediaType.APPLICATION_JSON);// <<<
英文:

You're getting status 415: unsupported media type.

You needed to changed add contentType() of the request which the controller accepts.
If your controller accepts application/json:

  1.         MockHttpServletRequestBuilder builder =
  2.                 MockMvcRequestBuilders
  3.                         .multipart(&quot;/attachment&quot;)
  4.                         .file(mockMultipartFile)
  5.                         .content(objectMapper.writeValueAsString(documentRequest))
  6.                         .contentType(MediaType.APPLICATION_JSON);// &lt;&lt;&lt;
