Unit testing HttpMediaTypeNotSupportedException在mockmvc post上

我有一个RestController和一个接受post请求的函数

@RequestMapping(path = "/auth",method = RequestMethod.POST)
public void authenticate(@RequestBody AuthenticationRequest authenticationRequest, HttpServletResponse httpServletResponse) throws  IOException {
}

我试图发出一个post请求

mockMvc.perform(post("/auth")
                    .contentType(MediaType.APPLICATION_JSON)
                    .content("{ \"foo\": \"bar\", \"fruit\": \"apple\" }".getBytes()))
            .andDo(print());

我收到

Resolved Exception:
         Type = org.springframework.web.HttpMediaTypeNotSupportedException

有解决办法吗

编辑：我还尝试在控制器上指定consumes=“application/json”，但仍然不起作用

例外情况是不接受“媒体类型”即“内容类型”

尝试将consumes=“application/json”添加到控制器函数中

@RequestMapping(path = "/auth",method = RequestMethod.POST,consumes = "application/json")
public void authenticate(@RequestBody AuthenticationRequest authenticationRequest, HttpServletResponse httpServletResponse) throws  IOException {
}

有关详细信息，请参阅spring文档

也许您可以提供整个异常以及更多的上下文？
