Required request part 'file' is not present in Spring Boot - spring

Question

I checked all of the simular posts and still couldnt find the solution.
Problem is Required request part 'file' is not present in test class.
I want to upload a file and save it to the database. Here is my rest controller #RestController:
#PostMapping(value = "/upload")
public ResponseEntity<LogoDto> uploadLogo(#RequestParam("file") MultipartFile multipartFile) {
return ResponseEntity.ok(logoService.createLogo(multipartFile));
}
and my test class:
#Test
public void createLogo2() throws Exception {
String toJsonLogoDto = new Gson().toJson(logoDto);
MockMultipartFile file = new MockMultipartFile("path", "url", MediaType.APPLICATION_JSON_VALUE, image);
LogoDto response = LogoDataTest.validLogoDto();
Mockito.when(logoServiceMock.createLogo(Mockito.any(MultipartFile.class))).thenReturn(response);
mockMvc.perform(MockMvcRequestBuilders.multipart("/brand-icon/upload")
.file(file)
.content(MediaType.APPLICATION_JSON_VALUE)
.contentType(MediaType.APPLICATION_JSON_VALUE)
.characterEncoding(CharEncoding.UTF_8))
.andDo(MockMvcResultHandlers.print())
.andExpect(MockMvcResultMatchers.status().isOk());
}
and my application.yml looks like this:
spring:
servlet:
multipart:
enabled: true
max-file-size: 2MB
max-request-size: 10MB
I tried to add consumes in my #PostMapping;
try to set literally every MediaTypes.. still get an error.
I appreciate all of your answer.

Answer 1

issue is in declaration of MockMultipartFile, first parameter should match controller #RequestParam param. So, in your case, should be:
MockMultipartFile file = new MockMultipartFile("file", "url", MediaType.APPLICATION_JSON_VALUE, image);
Also, I recommend to update your controller method to the following one:
#PostMapping(value = "/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<LogoDto> uploadLogo(#RequestPart("file") MultipartFile multipartFile) {
...
}
