Spring Boot Failing中的MultipartFile上传测试

Spring Boot Failing中的MultipartFile上传测试 - 不确定原因(MultipartFile upload test in Spring Boot Failing - not sure why)

我正在控制器中测试POST方法，该控制器通过MultipartFile处理图像上传。允许为空，但如果存在文件，则应将其上传。我写了一个单元测试，以确保它有效，但测试失败，返回404，我不知道为什么 - 可能是因为我不擅长阅读正在发生的事情。这是测试：

@Test public void saveAnEntryWhenPOSTNewUserWithAPicture() throws Exception { MockMultipartFile multiPFImage = new MockMultipartFile("ABCPicture", "abcpic.png", "img/png", "Generate bytes to simulate a picture".getBytes()); mockMvc.perform(MockMvcRequestBuilders.fileUpload("/newcontact") .file(multiPFImage) .param("userId", "12345") .param("name", "Picture Uploader User")) .andExpect(status().isOk()) .andExpect(content().string(containsString("savedContact"))); }

这是运行该测试产生的堆栈跟踪：

编辑：

这是正在测试的控制器方法：

@PostMapping(path = "/newContact") public String createNewContact(@ModelAttribute ContactDTO newContact) { Contact contact = new Contact(newContact.getUserId(), newContact.getName()); setOptionalContactFields(contact, newContact); contactDAO.save(contact); // contactId automatically generated here (via SQL autoIncrement) newContact.setContactId(contact.getContactId()); // update the newContact to include the contactId if (newContact.getContactImg() !=null ) { uploadContactProfileImg(newContact); // handles actual saving of image to persistence layer } return "savedContact"; // assumes template that can display all fields of a Contact will be returned }

任何有识之士将不胜感激。

I'm testing a POST method in a controller that handles the uploading of an image via a MultipartFile. It is allowed to be empty, but if there is a file present, it should upload it. I wrote a Unit test to make sure it worked, but the test is failing, returning a 404, and I'm not sure why - probably because I'm not adept at reading what's happening. Here's the test:

@Test public void saveAnEntryWhenPOSTNewUserWithAPicture() throws Exception { MockMultipartFile multiPFImage = new MockMultipartFile("ABCPicture", "abcpic.png", "img/png", "Generate bytes to simulate a picture".getBytes()); mockMvc.perform(MockMvcRequestBuilders.fileUpload("/newcontact") .file(multiPFImage) .param("userId", "12345") .param("name", "Picture Uploader User")) .andExpect(status().isOk()) .andExpect(content().string(containsString("savedContact"))); }

And here's the stack trace that results from running that test:

Edit:

Here is the controller method which is being tested:

@PostMapping(path = "/newContact") public String createNewContact(@ModelAttribute ContactDTO newContact) { Contact contact = new Contact(newContact.getUserId(), newContact.getName()); setOptionalContactFields(contact, newContact); contactDAO.save(contact); // contactId automatically generated here (via SQL autoIncrement) newContact.setContactId(contact.getContactId()); // update the newContact to include the contactId if (newContact.getContactImg() !=null ) { uploadContactProfileImg(newContact); // handles actual saving of image to persistence layer } return "savedContact"; // assumes template that can display all fields of a Contact will be returned }

Any insight would be greatly appreciated.
