如何防止 Spring Rest API 异常处理程序返回 HTTP 状态 400 的堆栈跟踪

Question

我正在尝试处理 Spring Rest 服务中的验证异常，如下所示：

@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，当此代码执行时，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。这在 Spring 3.1 中可行吗？

Answer 1

您可以将server.error.include-stacktrace=never响应包括堆栈跟踪的应用程序属性添加到 400 个响应中。

Answer 2

您可以将 Aspectj 用于这些目的。示例http://www.mkyong.com/spring3/spring-aop-aspectj-annotation-example/

您应该编写一个方面，它将捕获您的异常。

例子：

@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)
  }

}
