Spring 使用mockmvc检查异常场景时内容正文为空

概述：

我将在SpringMVC测试中使用定制的错误消息测试错误请求（400）。测试状态为400；但是，内容正文是空的

代码片段如下所示：

@Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        memberServiceController.setMemberDetailsApiController(mockMemberDetailsApiController);
        memberServiceController.setResourceMessage(mockResourceMessage);

        mockMvc = MockMvcBuilders.webAppContextSetup(context)
                .addFilter(new ShallowEtagHeaderFilter())
                .apply(documentationConfiguration(restDocumentation))
                .build();
    }

@Test
    public void getMemberDetails_whenStoreIdIsNull_setStatusToBadRequest() throws Exception {
        Mockito.doReturn("storeId is empty").when(mockResourceMessage).getMessage(MEMBER_ERROR_INVALID_STOREID);

        mockMvc.perform(get(URL)
                .header(REQUEST_HEADER_COOKIE, DEFAULT_COOKIE_VALUE)
                .param(REQUEST_PARAM_MEMBERSHIP_IDENTIFIER, "MEMBER1"))
                .andDo(MockMvcResultHandlers.print())
                .andDo(document("memberServices/GetMemberDetailsNullStoreId",
                        requestHeaders(
                                headerWithName(REQUEST_HEADER_COOKIE).description(REQUEST_HEADER_COOKIE_DESCRIPTION)
                        ),
                        requestParameters(
                                parameterWithName(REQUEST_PARAM_MEMBERSHIP_IDENTIFIER).description(REQUEST_PARAM_MEMBERSHIP_IDENTIFIER_DESCRIPTION)
                        )))
                .andExpect(status().isBadRequest())
                .andExpect(content().string(containsString("storeId is empty".toLowerCase())))
                .andReturn().getResponse();
    }

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = /retailer1/memberDetails
       Parameters = {membershipIdentifier=[MEMBER1]}
          Headers = {Cookie=[SESSION=67421bc3-36da-4b64-9aca-94edf57211f6]}

    Async started = false
     Async result = null

             View = null
            Model = null

     but: was ""

问题：

现在，如果有人能帮我找到一种方法，通过我定制的异常消息（“storeId为空”）获取错误请求，以便添加到生成的API文档中，并在API文档中生成类似以下内容的响应，我将不胜感激：

HTTP/1.1 400 Bad Request, 
storeId is empty 

---

问题与代码中的异常处理有关。我忘了在我的测试类中将GlobalControllerExceptionHandler类添加到@SpringApplicationConfiguration中，该类是我们的异常处理程序。因此，在添加以下内容后，我的问题解决了：

@SpringApplicationConfiguration(classes = {
        MemberRestControllerTest.class,
        MemberRestController.class,
        ResourceResultProcessor.class,
        GlobalControllerExceptionHandler.class
})
public class MemberRestControllerTest {
        ...
}

你检查过这个了吗？谢谢，我可以在检查这个链接后解决它。这个问题是由异常处理引起的
