aspectj 简单的模拟权限检查、事务、日志记录

 

package com.ij34.service;


public class Hello
{
    public void he()
    {
        System.out.println("执行Hello的he方法");
    }
    public int addUser(String name , String pass)
    {
        System.out.println("执行Hello的addUser方法：" + name);
        return 0;
    }
}

package com.ij34.service;


public class Hi
{

    public void hihi()
    {
        System.out.println("执行Hi组件的hihi()方法");
    }
}
