静态代理模式实现

以下是通过代理模式模拟电脑代理商卖电脑的场景。

package designpattern.proxy;

public interface Solder {
	
	public void sold();

}

 

package designpattern.proxy;

public class RealSolder implements Solder {

	@Override
	public void sold() {
		System.out.println("销售电脑");
	}

}

 

package designpattern.proxy;

public class ProxySolder implements Solder {
	
	private Solder solder;
	

	public ProxySolder() {
		super();
	}

	public ProxySolder(Solder solder) {
		super();
		this.solder = solder;
	}

	@Override
	public void sold() {
		this.solder.sold();
		System.out.println("卖东西，送东西");
	}

	public Solder getSolder() {
		return solder;
	}

	public void setSolder(Solder solder) {
		this.solder = solder;
	}
	
	public static void main(String[] args) {
		Solder solder = new ProxySolder(new RealSolder());
		solder.sold();
	}

}
