求助，SpringMVC用Junit4测试Controller中参数是实体类的方法时应该怎么写？

[Anapeach]

如下，当controller方法参数是String时可以这样写，那如果传入的是一个实体类呢？

@Test
    public void checkUserSignIn() throws Exception {
        MvcResult mvcResult = mvc.perform(MockMvcRequestBuilders.get("/api/signin/check").param("typeId","1003"))
                .andExpect(MockMvcResultMatchers.status().is(200))
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
        int status = mvcResult.getResponse().getStatus();
        System.out.println("请求状态码：" + status);
        String result = mvcResult.getResponse().getContentAsString();
        System.out.println("接口返回结果：" + result);
        JSONObject resultObj = JSON.parseObject(result);

    }

比如controller中的方法是这样时，要如何测试呢，求助大神

public R checkUserSignIn(@RequestBody User user){
/*...*/
}

    @Test
    public void checkUserSignIn() throws Exception {
        MvcResult mvcResult = mvc.perform(MockMvcRequestBuilders.get("/api/signin/check").content(JSON.toJsonString(你的对象)))
                .andExpect(MockMvcResultMatchers.status().is(200))
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
        int status = mvcResult.getResponse().getStatus();
        System.out.println("请求状态码：" + status);
        String result = mvcResult.getResponse().getContentAsString();
        System.out.println("接口返回结果：" + result);
        JSONObject resultObj = JSON.parseObject(result);

    }

MockMvcRequestBuilders.get("/api/signin/check").content(JSON.toJsonString(你的对象))
把对象转成json,把字符串丢到content里即可
