java.lang.AssertionError : Status expected:<200> but was:<400>

Question

这是我的 Controller ...

@RequestMapping(value = "/user", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE, headers = "Accept=application/json")
public @ResponseBody ResponseMessage getUser(@RequestBody AvailableUser uuid) {
    logger.info("enter into getuser method's body");
    return Manager.availableUser(uuid);
}

这是我的测试 Controller ...

@Test 
public void testgetUser() throws Exception 
{
    AvailableUser availableUser=new AvailableUser();
    List<String> lst =new ArrayList<String>();
    lst.add("test1");
    lst.add("test2");
    availableUser.setUuId(lst);
    this.mockMvc.perform(post("/user").contentType(MediaType.APPLICATION_JSON).accept(MediaType.APPLICATION_JSON))
        .andExpect(status().isCreated())
        .andExpect(status().isOk());
         when(Manager.availableUser(availableUser)).thenReturn(message);
}

我不知道 Controller 方法调用时如何传递对象("/user")表格testcontroller .

我收到错误消息 java.lang.AssertionError: Status expected:<200> but was:<400>

如果您使用 Jackson，最简单的方法是使用 ObjectMapper 实例将 AvailableUser 序列化为 JSON 字符串:

@Test 
public void testgetUser() throws Exception 
{
    // Same stuff
    ObjectMapper mapper = new ObjectMapper();
    this.mockMvc
        .perform(
                  post("/user")
                 .contentType(MediaType.APPLICATION_JSON)
                 .accept(MediaType.APPLICATION_JSON)
                 .content(mapper.writeValueAsString(availableUser))
        )
        .andExpect(status().isCreated())
        .andExpect(status().isOk());
    // Same as before
}
