Spring 引导失败中的 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，该方法通过 MultipartFile 处理图像上传。它可以为空，但如果存在文件，则应上传它。我写了一个单元测试来确保它有效，但测试失败，返回 404，我不确定为什么 - 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")));
}

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
}
如有任何见解，我们将不胜感激。
我发现你打错了MockMvcRequestBuilders.fileUpload("/newcontact")
应该是MockMvcRequestBuilders.fileUpload("/newContact")
补充：
你的 DTO 中有错字
public class ContactDTO {
private MultipartFile conactImg;
}
request multipart name应该和DTO一样，ABCPicture应该是conactImg
