java----靜態代理

靜態代理沒啥好說的，直接上代碼

package com.yk.aop.staticproxy;

import org.junit.jupiter.api.Test;

//1.接口
public interface IUserDao {
    void save();

    void find();
}
//2.實現類
 class UserDao implements IUserDao {

    public void save() {
        System.out.println("保存用戶");
    }

    public void find() {
        System.out.println("查詢用戶");
    }

    @Test
    public void test(){
        System.out.print(111);
    }
}

/**
 * 3.靜態代理
 */
class UserDaoProxy implements IUserDao {
    private IUserDao target;

    public UserDaoProxy(IUserDao target) {
        this.target = target;
    }

    public void save() {
        System.out.println("開啓事物");
        target.save();
        System.out.println("提交事務");
    }

    public void find() {
        System.out.println("查找前操做");
        target.find();
        System.out.println("查找後操做");
    }

}
