代理模式---动态代理之Cglib

目标类UserServiceImpl：

package com.ant.jdk8.proxy;

public class UserServiceImpl {

    public void deleteUser(){
        System.out.println("删除用户");
    }
    
}

代理类CglibProxy：

package com.ant.jdk8.proxy;

import net.sf.cglib.proxy.Enhancer;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

import java.lang.reflect.Method;

public class CglibProxy implements MethodInterceptor {

    private Enhancer enhancer = new Enhancer();

    public Object getProxy(Class clazz){
        enhancer.setSuperclass(clazz);
        enhancer.setCallback(this);
        return enhancer.create();
    }

    @Override
    public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
        System.out.println("---开始事务---");
        Object result = proxy.invokeSuper(obj,args);
        System.out.println("---提交事务---");
        return result;
    }
}

测试类App：

package com.ant.jdk8.proxy;

public class App {
    public static void main(String[] args) {
        CglibProxy proxy = new CglibProxy();
        UserServiceImpl userService = (UserServiceImpl)proxy.getProxy(UserServiceImpl.class);
        userService.deleteUser();
    }
}
