接口和实现类见LogBeforeAdvice的例子
package net.blogjava.dodoma.spring.aop;

import java.lang.reflect.Method;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.aop.AfterReturningAdvice;

public class LogAfterAdvice implements AfterReturningAdvice {
 protected static final Log log = LogFactory.getLog(LogAfterAdvice.class);
 public void afterReturning(Object returnVal, Method m, Object[] args,
   Object target) throws Throwable {
  // TODO Auto-generated method stub
  log.info("in the class "+this.getClass().getName()+"'s method afterReturning()");

  log.info("the target class is:" + target.getClass().getName());
  log.info("the target method is:" + m.getName());

  for (int i = 0; i < args.length; i++) {
   log.info("the method's args is:" + args[i]);
  }
  
  log.info("the returnValue is "+returnVal);
  //测试,如果返回装备发生了异常.将如何处理程序流程
  //throw new Exception("返回装备发生异常");
 }

}

测试代码

package net.blogjava.dodoma.spring.aop;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

public class HelloTest {
 protected static final Log log = LogFactory.getLog(HelloTest.class);

 /**
  * @param args
  * @throws Exception
  */
 public static void main(String[] args) throws Exception {
  // TODO Auto-generated method stub
  Resource rs = new ClassPathResource("beans.xml");
  BeanFactory bf = new XmlBeanFactory(rs);

  HelloI h = (HelloI) bf.getBean("theBean");
  log.info("starting...");
  try {
   log.info(h.sayHello("ma", "bin"));
  } catch (Exception e) {
   e.printStackTrace();
  }
  log.info("end...");
  
  
  ProxyFactory factory=new ProxyFactory();
  factory.addAdvice(new LogAfterAdvice());
  factory.setTarget(new Hello("hello"));
  try{
  HelloI hi=(HelloI)factory.getProxy();
  hi.sayHello("ma","bin");}
  catch(Exception e){e.printStackTrace();}
 }

}


在beans.xml中加入如下代码
<bean id="theLogAfterAdvice" class="net.blogjava.dodoma.spring.aop.LogAfterAdvice"/>

<property name="interceptorNames">
      <list>
        <value>theLogAfterAdvice</value><!--此时直接使用advice,表明这个类所有的实例,方法,都享受advice的拦截-->
       </list> 
</property>

切入点可省略,如需要的话
如

<!--切入点-->
  <!--Note: An advisor assembles pointcut and advice-->
  <bean id="theBeAdvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
    <property name="advice">
      <ref local="theLogAfterAdvice"/>
    </property>
    <!--匹配模式-->
    <property name="pattern">
      <value>.*</value>
    </property>
  </bean>
