使用TestRestTemplate进行Multipart POST请求的集成测试返回400

Question

我知道类似的问题已经在这里出现过几次,但是根据建议的修复并没有解决我的问题.

我有一个简单的控制器,具有以下端点:

@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> singleFileUpload(@RequestParam("file") MultipartFile file) {
    log.debug("Upload controller - POST: {}", file.getOriginalFilename());

    // do something
}

我正在尝试使用Spring为它编写集成测试,TestRestTemplate但我的所有尝试都以此结束400 - Bad Request(没有日志说明控制台出了什么问题).

控制器内的日志没有被击中,因此在到达之前失败了.

你能看看我的测试并建议我做错了什么吗？

@Test
public void testUpload() {
    // simulate multipartfile upload
    ClassLoader classLoader = getClass().getClassLoader();
    File file = new File(classLoader.getResource("image.jpg").getFile());

    MultiValueMap<String, Object> parameters = new LinkedMultiValueMap<String, Object>();
    parameters.add("file", file);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<MultiValueMap<String, Object>>(parameters, headers);

    ResponseEntity<String> response = testRestTemplate.exchange(UPLOAD, HttpMethod.POST, entity, String.class, "");

    // Expect Ok
    assertThat(response.getStatusCode(), is(HttpStatus.OK));
}

Answer 1

我尝试了以下方法:

@Test
public void testUpload() {
    LinkedMultiValueMap<String, Object> parameters = new LinkedMultiValueMap<String, Object>();
    parameters.add("file", new org.springframework.core.io.ClassPathResource("image.jpg"));

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    HttpEntity<LinkedMultiValueMap<String, Object>> entity = new HttpEntity<LinkedMultiValueMap<String, Object>>(parameters, headers);

    ResponseEntity<String> response = testRestTemplate.exchange(UPLOAD, HttpMethod.POST, entity, String.class, "");

    // Expect Ok
    assertThat(response.getStatusCode(), is(HttpStatus.OK));
}

正如你所看到的,我使用org.springframework.core.io.ClassPathResource了文件的as对象,ti就像魅力一样

我希望它有用
