如何使用Mockito测试异常处理程序，而没有真实的控制器调用（春季）
我有一个控制器，
@RequestMapping(value = "something/{year}", method = RequestMethod.GET)
@ResponseBody
public MyObject get(@PathVariable("year") int year throws MyException {
return myService.get(year);
}
如果一年不正确，它将丢弃错误，并且此错误是由我的ErrorInterceptor类捕获的，
@ExceptionHandler(value = {MyException.class})
protected ResponseEntity<Object> handleMyException(MyException ex, WebRequest request) {
System.out.println(ex.getMessage());
ResponseEntity<Object> res = handleExceptionInternal(ex, ex.getMessage(), new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR, request);
ResponseEntity<Object> response = getMyResponse((ServletWebRequest) request, res);
return response;
}
方法GetMyResponse创建了一个具有自定义错误消息（路径，代码错误等）的对象。 我的问题是，如何在不真正呼叫控制器的情况下使用Mockito对其进行测试。 我已经使用MockMvcBuilders.standalonesetup（Controller）.setControllerAdvice（myInterceptor）.build（）进行了测试。
我还尝试添加Mockito。和Mockity。
I have a Controller
@RequestMapping(value = "something/{year}", method = RequestMethod.GET)
@ResponseBody
public MyObject get(@PathVariable("year") int year throws MyException {
return myService.get(year);
}
If the year is not correct, it's gonna throw an error and this error is caught by my ErrorInterceptor class
@ExceptionHandler(value = {MyException.class})
protected ResponseEntity<Object> handleMyException(MyException ex, WebRequest request) {
System.out.println(ex.getMessage());
ResponseEntity<Object> res = handleExceptionInternal(ex, ex.getMessage(), new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR, request);
ResponseEntity<Object> response = getMyResponse((ServletWebRequest) request, res);
return response;
}
The method getMyResponse creates an object with customed error message (path, code error, etc.)
My question is how can I test it with Mockito without making a real call of the controller.
I've tested with MockMvcBuilders.standaloneSetup(controller) .setControllerAdvice(myInterceptor).build() but it's always null (I don't want to make a real call).
I also tried adding Mockito.when and Mockity.verify to fake the call but I can't get retrieve the path and stuff...

如果您只想知道拦截器是否正在返回正确的响应，则可以创建一个正在限制拦截器的类，并为
handlemyException提供公共包装方法。然后，您实例化了新课程，请致电包装器并断言返回的响应。If you just want to know if the interceptor is returning the correct response, you could create a class which is extenting the interceptor and provides an public wrapper method for
handleMyException. Then you instantiate that new class, call the wrapper and assert on the returned response.
