package com.shejimoshi;public class Main {public static void main(String[] args) {RequestParam requestParam new RequestParam(MJ, 3);if (requestParam.getTime()1){System.out.println(领导审批);if (requestParam.getTime()2){System.out.println(一级部门领导审批);if (requestParam.getTime()3){System.out.println(分管领导审批);}}}}
}使用责任链各司其职
抽象审批类AuditHandler,包含下一个处理者的引用nextAuditHandler,通过setNextAuditHandler方法进行注入,从而形成一条链抽象audit方法由各个处理者的实现类去实现各自的审批逻辑。 package com.shejimoshi;public abstract class AuditHandler {protected AuditHandler nextAuditHandler;public void setNextAuditHandler(AuditHandler nextAuditHandler) {this.nextAuditHandler nextAuditHandler;}public abstract void audit(RequestParam requestParam);
}
class DirectLeaderAuditHandler extends AuditHandler{Overridepublic void audit(RequestParam requestParam) {if (requestParam.getTime()1){System.out.println(班主任审批通过);}if (nextAuditHandler ! null){nextAuditHandler.audit(requestParam);}else {System.out.println(审批完成);}}
}
class FirstLeaderAuditHandler extends AuditHandler{Overridepublic void audit(RequestParam requestParam) {if (requestParam.getTime()2){System.out.println(学院审批通过);}if (nextAuditHandler ! null){nextAuditHandler.audit(requestParam);}else {System.out.println(审批完成);}}
}
class FenGuanLeaderAuditHandler extends AuditHandler{Overridepublic void audit(RequestParam requestParam) {if (requestParam.getTime()3){System.out.println(学校审批通过);}if (nextAuditHandler ! null){nextAuditHandler.audit(requestParam);}else {System.out.println(审批完成);}}
}
class Test{public static void main(String[] args) {AuditHandler handler new DirectLeaderAuditHandler();FirstLeaderAuditHandler firstLeaderAuditHandler new FirstLeaderAuditHandler();FenGuanLeaderAuditHandler fenGuanLeaderAuditHandler new FenGuanLeaderAuditHandler();handler.setNextAuditHandler(firstLeaderAuditHandler);firstLeaderAuditHandler.setNextAuditHandler(fenGuanLeaderAuditHandler);RequestParam requestParam new RequestParam(MJ, 2);handler.audit(requestParam);}
