MocMVC给出HttpMessageNotReadableException
我仍在学习有关测试的方法，并且尝试使MockMvc测试对我有用。这是一个简单的REST控制器，目前仅使用帖子中json的信息进行一些身份验证。我实际上已经实现了代码，所以我知道它正在工作，因为我以json格式获取了正确的响应，正确的输入和错误消息。我的问题是，即使实际代码有效，测试仍会因HttpMessageNotReadableException而失败，因此我假设我的测试设置不正确。你们能提供的任何帮助都会很棒。
这是我的控制器
@Controllerpublic class RequestPaymentController {
protected final Log logger = LogFactory.getLog(getClass());
private PaymentService paymentService;
private LoginService loginService;
@Autowired
public void setPaymentService(PaymentService paymentService){
this.paymentService = paymentService;
}
@Autowired
public void setLoginService(LoginService loginService){
this.loginService = loginService;
}
@RequestMapping(value = "/requestpayment", method = RequestMethod.POST, headers="Accept=application/json")
@ResponseBody
public ResponseEntity<PaymentResult> handleRequestPayment(@RequestBody PaymentRequest paymentRequest, HttpServletRequest request, HttpServletResponse response, BindingResult result) throws Exception{
ResponseEntity<PaymentResult> responseEntity = null;
new LoginValidator().validate(paymentRequest, result);
boolean valid = loginService.isLoginValid(paymentRequest, result);
if (valid){
responseEntity = setValidResponse(paymentRequest);
}else {
throw new TumsException("exception message");
}
return responseEntity;
}
private ResponseEntity<PaymentResult> setValidResponse(PaymentRequest paymentRequest){
PaymentResult paymentResult = paymentService.getResults(paymentRequest);
return new ResponseEntity<PaymentResult>(paymentResult, HttpStatus.OK);
}
}
这是我的测试代码：
public class RequestPaymentControllerTest {PaymentService mockPaymentService;
RequestPaymentController requestPaymentController;
HttpServletRequest mockHttpServletRequest;
HttpServletResponse mockHttpServletResponse;
PaymentRequest mockPaymentRequest;
BindingResult mockBindingResult;
LoginService mockLoginService;
PaymentResult mockPaymentResult;
MockMvc mockMvc;
@Before
public void setUp() throws Exception {
mockPaymentService = createMock(PaymentService.class);
mockHttpServletRequest = createMock(HttpServletRequest.class);
mockHttpServletResponse = createMock(HttpServletResponse.class);
mockPaymentRequest = createMock(PaymentRequest.class);
requestPaymentController = new RequestPaymentController();
mockBindingResult = createMock(BindingResult.class);
mockLoginService = createMock(LoginService.class);
requestPaymentController.setPaymentService(mockPaymentService);
mockPaymentResult = createMock(PaymentResult.class);
mockMvc = MockMvcBuilders.standaloneSetup(new RequestPaymentController()).build();
}
@After
public void tearDown() throws Exception {
mockPaymentService = null;
mockHttpServletRequest = null;
mockHttpServletResponse = null;
mockPaymentRequest = null;
requestPaymentController = null;
mockBindingResult = null;
mockLoginService = null;
mockPaymentResult = null;
mockMvc = null;
}
@Test
public void testHandleRequestPayment() throws Exception{
initializeStateForHandleRequestPayment();
createExpectationsForHandleRequestPayment();
replayAndVerifyExpectationsForHandleRequestPayment();
}
private void initializeStateForHandleRequestPayment(){
}
private void createExpectationsForHandleRequestPayment(){
mockPaymentRequest.getServiceUsername();
expectLastCall().andReturn("testuser");
mockPaymentRequest.getServicePassword();
expectLastCall().andReturn("password1!");
mockLoginService.isLoginValid(mockPaymentRequest,mockBindingResult);
expectLastCall().andReturn(true);
mockPaymentService.getResults(mockPaymentRequest);
expectLastCall().andReturn(mockPaymentResult);
}
private void replayAndVerifyExpectationsForHandleRequestPayment() throws Exception{
replay(mockPaymentService, mockBindingResult, mockHttpServletRequest, mockHttpServletResponse, mockPaymentRequest, mockLoginService);
requestPaymentController.setLoginService(mockLoginService);
requestPaymentController.handleRequestPayment(mockPaymentRequest, mockHttpServletRequest, mockHttpServletResponse, mockBindingResult);
mockMvc.perform(post("/requestpayment")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON))
.andDo(print())
.andExpect(status().isBadRequest());
verify(mockPaymentService, mockBindingResult, mockHttpServletRequest, mockHttpServletResponse, mockPaymentRequest, mockLoginService);
}
}
andDo（print（））的结果是：
MockHttpServletRequest: HTTP Method = POST
Request URI = /requestpayment
Parameters = {}
Headers = {Content-Type=[application/json], Accept=[application/json]}
Handler:
Type = portal.echecks.controller.RequestPaymentController
Method = public org.springframework.http.ResponseEntity<portal.echecks.model.PaymentResult> portal.echecks.controller.RequestPaymentController.handleRequestPayment(portal.echecks.model.PaymentRequest,javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse,org.springframework.validation.BindingResult) throws java.lang.Exception
Resolved Exception:
Type = org.springframework.http.converter.HttpMessageNotReadableException
ModelAndView:
View name = null
View = null
Model = null
FlashMap:
MockHttpServletResponse:
Status = 400
Error message = null
Headers = {}
Content type = null
Body =
Forwarded URL = null
Redirected URL = null
Cookies = []
Process finished with exit code 0
如您所见，当我期望错误的请求状态时，测试通过了，但是我已经记录了日志，而且我知道我发回的ResponseBody的状态为200。就像我说的那样，这是我第一次使用MockMvc，所以我认为我没有进行正确的设置。有什么建议么？
回答：
安HttpMessageNotReadableException是
当read方法失败时，由HttpMessageConverter实现抛出。
您还会收到400错误的请求。所有这些都应该告诉您，您没有发送服务器期望的内容。您的服务器期望什么？
@RequestMapping(value = "/requestpayment", method = RequestMethod.POST, headers="Accept=application/json")@ResponseBody
public ResponseEntity<PaymentResult> handleRequestPayment(@RequestBody PaymentRequest paymentRequest, HttpServletRequest request, HttpServletResponse response, BindingResult result) throws Exception{
这里最主要的是带@RequestBody注释的参数。因此，您要告诉服务器尝试PaymentRequest从HTTP
POST请求的主体中反序列化实例。
让我们来看看您的要求
mockMvc.perform(post("/requestpayment") .contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON))
.andDo(print())
.andExpect(status().isBadRequest());
我看不到您为请求提供正文。那里应该有一个content(String)电话来设置POST请求的内容。此内容应为的JSON序列化PaymentRequest。
请注意，由于使用StandaloneMockMvcBuilder，您可能需要自行设置HttpMessageConverter实例，即。一个MappingJackson2HttpMessageConverter序列化和反序列化JSON。
请注意，该BindingResult参数应紧随与其相关的参数之后。像这样
@RequestMapping(value = "/requestpayment", method = RequestMethod.POST, headers="Accept=application/json")@ResponseBody
public ResponseEntity<PaymentResult> handleRequestPayment(@Valid @RequestBody PaymentRequest paymentRequest, BindingResult result, HttpServletRequest request, HttpServletResponse response) throws Exception{
别忘了@Valid。
请注意
requestPaymentController.setLoginService(mockLoginService);requestPaymentController.handleRequestPayment(mockPaymentRequest, mockHttpServletRequest, mockHttpServletResponse, mockBindingResult);
与MockMvc您正在执行的测试完全无关。
