我正在使用Spring Boot版本='1.4.0.RC1',并使用Spring Boot Stormpath 1.0.2。
我尝试使用multipart文件上传,但在控制器中MultipartFile始终为空。
当我使用@RequestPart("file")时,出现以下信息:"status":400,"error":"Bad Request","exception":"org.springframework.web.multipart.support.MissingServletRequestPartException","message":"Required request part 'file' is not present"
当我使用@RequestPart(name = "file", required = false)时,该部分始终为空。
但是,如果我将HttpServletRequest参数添加到控制器中,我可以直接从请求中获取文件部分,因此我知道它实际存在。
这是控制器,在下面的代码中checkNotNull(part)
始终成功,而checkNotNull(imageFile)
始终失败:
@PostMapping("{username}/profilePhoto")
public ResponseEntity<?> saveProfilePhoto(@PathVariable("username") String username,
@RequestPart(name = "file", required = false) MultipartFile imageFile,
HttpServletRequest request) {
try {
Part part = request.getPart("file");
checkNotNull(part);
checkNotNull(imageFile);
} catch (IOException | ServletException ex) {
throw InternalServerErrorException.create();
}
// Transfer the multipart file to a temp file
File tmpFile;
try {
tmpFile = File.createTempFile(TMP_FILE_PREFIX, null);
imageFile.transferTo(tmpFile);
} catch (IOException ex) {
log.error("Failed to create temp file", ex);
throw InternalServerErrorException.create();
}
// Execute the use case
updateUserProfilePhoto.execute(username, tmpFile);
// Delete the temp file
FileUtils.deleteQuietly(tmpFile);
return ResponseEntity.status(HttpStatus.CREATED).build();
}
我的集成测试使用了Retrofit:
@Multipart
@POST("users/{username}/profilePhoto")
Call<Void> uploadProfilePhoto(@Path("username") String username,
@Part("file") RequestBody profilePhoto);
...
@Test
public void saveProfilePhoto_shouldSavePhoto() throws IOException {
// Given
String usernamme = usernames[0];
Resource testImageResource = context.getResource("classpath:images/test_image.jpg");
File imageFile = testImageResource.getFile();
RequestBody body = RequestBody.create(okhttp3.MediaType.parse("image/*"), imageFile);
// When
Response<Void> response = getTestApi().uploadProfilePhoto(usernamme, body).execute();
// Then
assertThat(response.code()).isEqualTo(201);
}
我正在使用自动配置,因此我的唯一自定义配置类是用于配置Stormpath的:
@Configuration
public class SpringSecurityWebAppConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.apply(stormpath());
}
}
更新: 这是发出的请求。我不确定如何在多部分解析器中启用日志记录。

有什么想法是怎么回事吗?

中添加调试级别的日志记录,以查看它是否解释了请求的多部分组件? - Shawn Clark
