AOP：代理思想（没有考虑到Spring）

文件目录：

package com.wangcf.entity;

public class User {
    private int id;
    private String name;
    private String password;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
}

想要执行的方法：

package com.wangcf.manager;

import com.wangcf.entity.User;

public class UserManager {
    
    private LogManager logManger;
    private AuthorityManager autManager;
    public UserManager(){
        this.logManger=new LogManager();
        this.autManager=new AuthorityManager();
    }
    
    public void add(User user){
        autManager.isAllown();
        logManger.add();
        System.out.println("UserManager add...");
    }
    
    public void del(User user){
        autManager.isAllown();
        logManger.add();
        System.out.println("UserManager del...");
    }
    
    public void update(User user){
        autManager.isAllown();
        logManger.add();
        System.out.println("UserManager update...");
    }
}

切面拦截，

package com.wangcf.manager;

public class AuthorityManager {
    public boolean isAllown(){
        boolean flag=true;
        System.out.println("权限检查..");
        return true;
    }
}

package com.wangcf.manager;

public class LogManager {
    
    public void add(){
        System.out.println("添加日志...");
    }
}

测试类：

package com.wangcf.test;

import com.wangcf.manager.UserManager;

public class testAction {
    public static void main(String[] args) {
        UserManager userManager=new UserManager();
        userManager.add(null);
    }
}
