Smajl :
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));
}

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
