  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;

  }

  
  

  }
