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());
}
