1。配置包扫描和启用AOP自动代理

<context:component-scan base-package=“action,service,dao,domain,aspect”>
 <context:include-filter type=“annotation”
 expression=“org.aspectj.lang.annotation.Aspect”/>
 </context:component-scan>
<aop:aspectj-autoproxy/>

2。类中使用Aspect和@After等注解

@Aspect
 public class LogAspect {
 @AfterReturning(returning=“rvt”,pointcut=“execution(* service.impl..(…))”)
 public void log(Object rvt)
 {
 System.out.println("it is "+(int)rvt);
 }}
