sales.setSuccessor(lead);就是一级一级上传的。如果权限不够就在工厂方法里面set处理了

public class PriceHandlerFactory {

/*

* 创建PriceHandler的工厂方法

*/

public static PriceHandler createPriceHandler() {

PriceHandler sales = new Sales();

PriceHandler lead = new Lead();

PriceHandler man = new Manager();

PriceHandler dir = new Director();

PriceHandler vp = new VicePresident();

PriceHandler ceo = new CEO();

sales.setSuccessor(lead);

lead.setSuccessor(man);

man.setSuccessor(dir);

dir.setSuccessor(vp);

vp.setSuccessor(ceo);

return sales;

}

}
