MockMvc Test Spring抛出org.springframework.web.HttpMediaTypeNotSupportedException

Question

我正在尝试跟踪异常org.springframework.web.HttpMediaTypeNotSupportedException试图测试Json控制器.

控制器中的方法是:

@RequestMapping(value = "/report", method = RequestMethod.PUT)
    public @ResponseBody DatosJsonVO report(@RequestHeader(value = "hash", required = true) String hash,
            @RequestBody ReportVO report) {
}

我的测试方法如下:

@Test
    public void reportarPreguntaSesionInvalida() throws Exception { 
        ReportVO report = new ReportVO();
        report.setIdQuestion(1);
        report.setIssue("Wrong answer");
        mockMvc.perform(put("/json/report").header("hash", "123456789")
                .accept(MediaType.APPLICATION_JSON).content(asJsonString(report))).andDo(print())
                .andExpect(content().string("{\"code\":2,\"message\":\"Session error\",\"data\":null}"));
    }

但是,我得到了这样的答复:

MockHttpServletRequest:
         HTTP Method = PUT
         Request URI = /json/report
          Parameters = {}
             Headers = {hash=[8.16615469E8], Accept=[application/json]}
             Handler:
                Type = com.controller.json.QuestionsJsonController
               Async:
   Was async started = false
        Async result = null
  Resolved Exception:
                Type = org.springframework.web.HttpMediaTypeNotSupportedException
        ModelAndView:
           View name = null
                View = null
               Model = null
            FlashMap:
MockHttpServletResponse:
              Status = 415
       Error message = null
             Headers = {}
        Content type = null
                Body = 
       Forwarded URL = null
      Redirected URL = null
             Cookies = []

我的Spring版本是4.0.0.RELEASE

        mockMvc.perform(put("/json/report").header("hash", "123456789")
            .accept(MediaType.APPLICATION_JSON)
            .content(asJsonString(report)))
            .contentType(MediaType.APPLICATION_JSON)
            .andDo(print())
            .andExpect(content().string("{\"code\":2,\"message\":\"Session error\",\"data\":null}"));
