Java 中静态代理的基本用法

package www.demo10;
interface ClothFactory{
    void productionCloth();
}
//代理类
class Agency implements ClothFactory{
    private ClothFactory clothFactory;
   public Agency(ClothFactory clothFactory){
        this.clothFactory =clothFactory;
    }
    @Override
    public void productionCloth() {
        System.out.println("代理类");
        clothFactory.productionCloth();
        System.out.println("代理类。。。。。");
    }
}
//被代理类
class ByProxy implements ClothFactory{
    @Override
    public void productionCloth() {
        System.out.println("Nike最近在生产一批运动服");
    }
}
public class StaticProxyTest {
    public static void main(String[] args) {
        ByProxy byProxy = new ByProxy();
        Agency agency = new Agency(byProxy);
        agency.productionCloth();
    }
}
