XML兑现AOP（转）

Java代码

package cn.itcast.server;
public interface IPersonService {
public void save(String name);
public String getPersonName(Integer id);
public void update(String name,Integer id);
}

Java代码

package cn.itcast.server.impl;
import cn.itcast.server.IPersonService;
public class PersonServiceBean2 implements IPersonService {
public String getPersonName(Integer id) {
System.out.println("这是getPersonName方法" );
return "xxx" ;
}
public void save(String name) {
// throw new RuntimeException("我是例外");
System.out.println("这是save方法" );
}
public void update(String name, Integer id) {
System.out.println("这是update方法" );
}
}

Java代码

package cn.itcast.server;
import org.aspectj.lang.ProceedingJoinPoint;
public class MyInteceptor2 {
public void doAccessCheck(){
System.out.println("这里输出的是前置通知 " );
}
public void doAfterReturning(){
System.out.println("这里输出的是后置通知 " );
}
public void doAfterReturn(){
System.out.println("这里输出的是最终通知" );
}
public void doAfterThrowing(){
System.out.println("这里输出的是例外通知 " );
}
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable{
//判断用户是否具有权限
System.out.println("进入方法" );
Object result = pjp.proceed();
System.out.println("退出方法" );
return result;
}
}
