使用TestRestTemplate进行Multipart POST请求的集成测试返回400(Integration test with TestRestTemplate for Multipart

使用TestRestTemplate进行Multipart POST请求的集成测试返回400(Integration test with TestRestTemplate for Multipart POST request returns 400)

我知道类似的问题已经在这里已经好几次，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 TestRestTemplate为它编写集成测试，但我的所有TestRestTemplate都以400 - Bad Request结尾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)); }

I know that similar question has been here already couple of times but following suggested fixes did not solve my problem.

I have a simple controller with the following endpoint:

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

I am trying to write an integration test for it using Spring TestRestTemplate but all of my attemps end with 400 - Bad Request (no logs clarifying what went wrong in console).

The log inside the controller did not get hit so it failed before getting there.

Could you please take a look on my test and suggest what am I doing wrong?

@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)); }

最满意答案

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，我使用了org.springframework.core.io.ClassPathResource作为文件的对象，而ti就像一个魅力

我希望它有用

I tried the following:

@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)); }

As you can see I used the org.springframework.core.io.ClassPathResource as object for the file and ti worked like a charm

I hope it's useful
