我正在尝试在Spring Rest服务中处理Validation异常，如下面给出的代码：
@Produces("application/json")
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public @ResponseBody ResponseEntity<ValidationErrorDTO> processValidationError(MethodArgumentNotValidException ex) {
BindingResult result = ex.getBindingResult();
List<FieldError> fieldErrors = result.getFieldErrors();
ResponseEntity<ValidationErrorDTO> re = new ResponseEntity<>(processFieldErrors(fieldErrors), HttpStatus.BAD_REQUEST);
return re;
}
但是，当执行此代码时，它会返回附加到JSON响应的堆栈跟踪。我想摆脱这个堆栈跟踪，只返回JSON错误响应。这可以用Spring 3.1吗？

你可以这样做：
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ModelAndView methodArgumentError(HttpServletRequest req, Exception exception) {
return new JsonError(exception.getMessage()).asModelAndView();
}
答案 1 :(得分：1)
@Order(Ordered.HIGHEST_PRECEDENCE)
在您的方法上使用@Order(Ordered.HIGHEST_PRECEDENCE) 它将起作用
答案 2 :(得分：0)
同时使用@ResponseBody和ResponseEntity并不常见。我认为你应该清楚地决定你想做什么。 - 然后你应该检查你的内部框架类com.ebay.raptor.kernel.dispatcher.HttpDispatchCommand，因为这是抛出异常的那个。
答案 3 :(得分：0)
您只需添加应用程序属性server.error.include-stacktrace=never即可响应，该响应将堆栈跟踪包括在400个响应中。
答案 4 :(得分：0)
如果错误仅返回给用户而不用于调试，则可以在 MethodArgumentNotValidException 中将堆栈跟踪设置为null。
或者，您也可以使用 @JsonIgnore 批注覆盖 getStackTrace（）
@JsonIgnore
@Override
public StackTraceElement[] getStackTrace() {
return super.getStackTrace();
}
编辑：我尝试了所有其他解决方案，但没有一个对我有用。
答案 5 :(得分：-1)
您可以将Aspectj用于这些目的。示例http://www.mkyong.com/spring3/spring-aop-aspectj-annotation-example/
你应该写一个方面，这将抓住你的例外。
示例：
@Aspect
public class AroundExample {
@Around
pointcut = "execution(* your.package.Class.processValidationError(..))",
throwing= "error")
public Object doSomeStuff(ProceedingJoinPoint pjp, Throwable error) throws Throwable {
Object[] args = joinPoint.getArgs(); // change the args if you want to
Object retVal = pjp.proceed(args); // run the actual method (or don't)
return retVal; // return the return value (or something else)
}
}
