How to PUT multipart/form-data using Spring MockMvc?

Question

I have a controller\'s method with a PUT method, which receives multipart/form-data:

   @RequestMapping(value = \"/putIn\", method = RequestMeth         


        

Answer 1

You can pass both foo and file

Try rewrite you controller like:

@RequestMapping(value = "/putIn", method = RequestMethod.PUT)
public Foo updateFoo(
    HttpServletRequest request,
    @RequestPart Foo foo,
    @RequestPart MultipartFile file) {
    ...
}

And test looks like:

    MockMultipartFile file = new MockMultipartFile("file", "dummy.csv",
            "text/plain", "Some dataset...".getBytes());
    // application/json if you pass json as string
    MockMultipartFile file2 = new MockMultipartFile("foo", "foo.txt",
            "application/json", "Foo data".getBytes());

    MockMultipartHttpServletRequestBuilder builder =
            MockMvcRequestBuilders.multipart("/test1/datasets/set1");
    builder.with(new RequestPostProcessor() {
        @Override
        public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {
            request.setMethod("PUT");
            return request;
        }
    });
    mvc.perform(builder
            .file(file)
            .file(file2))
            .andExpect(status().ok());
