Spring Controller @RequestBody with file upload is it possible?
I couldn't find a way to use @RequestBody.
However, you can do something like this:
@RequestMapping(value = "/uploadStuff", method = RequestMethod.POST)
public MyViewDto doStuff(@RequestPart("json") @Valid MyDto dto,
@RequestPart("file") MultipartFile file) { ... }
You can test it like this:
MockMultipartFile jsonFile = new MockMultipartFile("json", "",
"application/json", "{}".getBytes());
MockMultipartFile dataFile = new MockMultipartFile("file", "foo.zip", "application/octet-stream", bytes);
mockMvc.perform(fileUpload("/uploadStuff")
.file(dataFile)
.file(jsonFile))
.andExpect(status().isOk());
Please add the following bean in your spring-servlet.xml to add the support for multipart request.
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />
Also don't forget to add the dependency for commons-fileupload jar
You can actually simplify your life here since all you are doing is submitting a form that contains some fields and file. You don't need @RequestBody for what you are trying to do. You can use regular Spring MVC features, so your controller method would look like:
@ResponseBody
public WebResponse<Boolean> updateEUSettings(
Locale locale,
@Valid EUPSettingsWrapper endUserPortalSettingsWrapper,
@RequestParam(value = "file1", required = true) MultipartFile logo
) {
}
The client that submits the request to this controller will need to have a form with enctype="multipart/form-data"
.
In your Spring MVC test you would write something like this:
getMockMvc().perform(fileUpload(uri).file("file1", "some-content".getBytes())
.param("someEuSettingsProperty", "someValue")
.param("someOtherEuSettingsProperty", "someOtherValue")
.accept(MediaType.APPLICATION_JSON)
.contentType(MediaType.MULTIPART_FORM_DATA))
.andExpect(status().isOk());
