一般发生这样的错误的原因，是由于你的通知方法有参数，需要在@Pointcut( "execution(* com.fishwasser.action.UserAction.*(..))" ) 添加args()。

如果是@AfterReturning，那么就需要配置returning参数。如：

   /**

     * 日志记录功能

     */

    @AfterReturning(returning="result" ,pointcut="execution(* cn..*.*Service.*(..))")

    public void log(Object result){

        if(result ==null){

            System.out.println("数据库中无结果...");

        }else{

            System.out.println("数据库中有结果...");

        }

    }

如果是@AfterThrowing ，那么需要配置throwing参数。如下代码：

   /**

     * 模拟异常处理

     */

    @AfterThrowing(pointcut="execution(* cn..*.*Service.*(..))",throwing="ex")

    public void processException(Throwable ex){

        System.out.println("异常信息为："+ex.getMessage());

    }
