spring中如何实现静态代理？

以下为实现的代码：

Rent.1ava——抽象角色

public interface Rent {

public void rent();

Host.java 真实角色

public class Host implements Rent{

public void rent(){

System.out.println("房屋出租");

}

Proxy.java 代理角色

public class Proxy implements Rent{

private Host host;

public Proxy()

public Proxy(Host host)(

this.host whost;

public void sethost(Host host){

this.host -host;

//租房

public void rent(){

seeHouse():

host.rent(); fare();//看房

private void seeHouse(l

System.out.println(“带房客看房”)

//收中介费

private void fare()

System.out.println(收取中介费)

}

}

 

Client.java 客户

public class client{

public static void main(string[] args){

Host host = new Host();

Proxy proxy=new Proxy(host); 

proxy.rent();

}

}
