junit java.lang.AssertionError: Status expected:<200> but was:<405>

spring项目进行junit测试出现如下错误

java.lang.AssertionError: Status expected:<200> but was:<405>     at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60)     at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89)     at org.springframework.test.web.servlet.result.StatusResultMatchers$5.match(StatusResultMatchers.java:549)     at org.springframework.test.web.servlet.MockMvc$1.andExpect(MockMvc.java:141

http  stauts状态返回的是405

405 - 用来访问本页面的 HTTP 谓词不被允许（方法不被允许） 

要调查controller类中的方法请求是get还是post

@RequestMapping(value = "/msg/update" ,method = RequestMethod.GET)

如何controller类请求设置为get那么测试类中也要使用get

@Test
    public void testUpdateMsg() throws Exception {
        mockMvc.perform(get("/ms/update", "json").accept(MediaType.APPLICATION_JSON)
                .param("id", "1")
                .param("title", "abc")
                )
                .andDo(print())
                .andExpect(status().isOk());

}

如果controller求情设置为post那么junit测试代码应该用post("/ms/update", "json")
