public class ExceptionAdvisor implements ThrowsAdvice {//    @AfterThrowing(pointcut = "execution(* com.ningpai..*.*(..))")    public void afterThrowing(Method method, Object[] args, Object target, Exception ex) throws Throwable {        // 在后台中输出错误异常异常信息，通过log4j输出。//        Logger log = Logger.getLogger(target.getClass());//        for (int i = 0; i < args.length; i++) {//            log.error("arg[" + i + "]: " + args[i]);//        }//        log.error("Exception class: " + ex.getClass().getName());//        log.error("ex.getMessage():" + ex.getMessage());//        log.error(ex);        ex.printStackTrace();    }}
