在Spring Boot中使用MockMvc测试RESTAPI的发布方法

Question

我一直收到InvalidMediaTypeException 这是我的帖子方法

PostMapping("/notes")
public Note createNote(@Valid @RequestBody Note note) {
        return noteRepository.save(note);
    }

这是我的测试方法

@Test //Testing post request 
public void TestPostMethods() throws Exception {
    Note notes = new Note();
    notes.setTitle("My Fifth Api");
    notes.setContent("Api building is fun");
    notes.setCreatedAt(new Date(21032019));
    notes.setUpdatedAt(new Date(21032019));

        RequestBuilder requestBuilder = MockMvcRequestBuilders
                .post("notes/")
                .accept(MediaType.APPLICATION_JSON_VALUE).contentType(ObjectToJson.getObjectData(notes))
                .contentType(MediaType.APPLICATION_JSON_VALUE);

        MvcResult result = mockMvc.perform(requestBuilder).andReturn();

        MockHttpServletResponse response = result.getResponse();

        assertEquals(HttpStatus.CREATED.value(), response.getStatus());


}

这是堆栈跟踪
