安全代理模式实例订单系统

MyEclipse自动生成的UML图，好像有一点丑。。。

实现的相同接口 

package Dingdan;

public interface IOrder {
	String GetproductName();

	void SetproductName(String productName, String user);

	int GetOrderNum();

	void SetOrderNum(int OrderNum, String user);

	String GetOrderUser();

	void SetOrderUser(String Orderuser,String user);

}

真实订单

package Dingdan;

public class Order implements IOrder {
  private String Pname;
  private int Onum;
  private String Ouser;
  
	public Order(String pname, int onum, String ouser) {

		Pname = pname;
		Onum = onum;
		Ouser = ouser;
	}

	@Override
	public String GetproductName() {
		// TODO 自动生成的方法存根
		return Pname;
	}

	@Override
	public void SetproductName(String productName, String user) {
		this.Pname=productName;

	}

	@Override
	public int GetOrderNum() {
		return Onum;
	}

	@Override
	public void SetOrderNum(int OrderNum, String user) {
		this.Onum=OrderNum;

	}

	@Override
	public String GetOrderUser() {
		
		return Ouser;
	}

	@Override
	public void SetOrderUser(String Orderuser, String user) {
		this.Ouser=Orderuser;

	}

}

订单代理

package Dingdan;

public class ProxyOrder implements IOrder {
    private Order ord=null;
    
	public ProxyOrder(Order ord) {
		
		this.ord = ord;
	}

	public String GetproductName() {
		
		return this.ord.GetproductName();
	}

	@Override
	public void SetproductName(String productName, String user) {
		if(user!=null&&user.equals(this.ord.GetOrderUser()))
			ord.SetproductName(productName,user);
		else
			System.out.println("对不起您没有权限");

	}

	@Override
	public int GetOrderNum() {
	return this.ord.GetOrderNum();
	}

	@Override
	public void SetOrderNum(int OrderNum, String user) {
     if(user!=null&&user.equals(this.ord.GetOrderUser()))
    	 ord.SetOrderNum(OrderNum,user);
     else
    	 System.out.println("对不起，您没有权限");
	}

	@Override
	public String GetOrderUser() {
		return this.ord.GetOrderUser();
	}

	@Override
	public void SetOrderUser(String Orderuser, String user) {
		if(user!=null&&user.equals(this.ord.GetOrderUser()))
			ord.SetOrderUser(Orderuser,user);
		else
			System.out.println("对不起，您没有权限");
	}

}

 客户端

package Dingdan;

public class Test {
	public static void main(String args[])

	{Order o1=new Order("设计模式",100,"张三");
	ProxyOrder po=new ProxyOrder(o1);
	po.SetOrderNum(123,"李四");
	po.SetOrderUser("王五", "李四");
	System.out.println(po.GetOrderNum());
	po.SetproductName("五年高考", "张三");
	System.out.println(po.GetproductName());
	po.SetOrderUser("李四", "张三");
	po.SetOrderNum(150, "李四");
	System.out.println(po.GetOrderNum());
	}
}
