实验15:职责链模式

[实验任务一]:财务审批

某物资管理系统中物资采购需要分级审批,主任可以审批1万元及以下的采购单,部门经理可以审批5万元及以下的采购单,副总经理可以审批10万元及以下的采购单,总经理可以审批20万元及以下的采购单,20万元以上的采购单需要开职工大会确定。现用职责链模式设计该系统。

直接放源码:

#include <iostream>
#include <string>
using namespace std;

class ShoppingRequest
{
public:
    ShoppingRequest(string shoppingReaso,double billMone){
        ShoppingReason=shoppingReaso;
        billMoney=billMone;
    }
    string getShoppingReason() {
        return ShoppingReason;
    }
    void setShoppingReason(string shoppingReaso) {
        ShoppingReason = shoppingReaso;
    }

    double getBillMoney() {
        return billMoney;
    }

    void setBillMoney(double billMone) {
        billMoney = billMone;
    }
private:
    string ShoppingReason;
    double billMoney;
};


class Leader
{
public:
    Leader(string nam){
        name=nam;
    }
    void setSuccessor(Leader* successo){
        successor=successo;
    }
    virtual void handleRequest(ShoppingRequest* request) = 0;
protected:
    string name;
    Leader* successor;
};


class Director : public  Leader   //PM:Project manager项目经理
{
public:
    Director(string name):Leader(name){};
    void handleRequest(ShoppingRequest* request){
        if(request->getBillMoney()<10000.00){
            cout <<"主任"<<name<<"处理物资采集:"<<
                 request->getShoppingReason()<<
                 ",批准采购资金为:"<<request->getBillMoney()<<"RMB"<< endl;
        }else{
            successor->handleRequest(request);
        }
    }
};

class DepartmentManager : public  Leader   //PM:Project manager项目经理
{
public:
    DepartmentManager(string name):Leader(name){};
    void handleRequest(ShoppingRequest* request){
        if(request->getBillMoney()<50000.00){
            cout <<"部门经理"<<name<<"处理物资采集:"<<
                 request->getShoppingReason()<<
                 ",批准采购资金为:"<<request->getBillMoney()<<"RMB"<< endl;
        }else{
            successor->handleRequest(request);
        }
    }
};

class ViceManager : public  Leader   //PM:Project manager项目经理
{
public:
    ViceManager(string name):Leader(name){};
    void handleRequest(ShoppingRequest* request){
        if(request->getBillMoney()<100000.00){
            cout <<"副经理"<<name<<"处理物资采集:"<<
                 request->getShoppingReason()<<
                 ",批准采购资金为:"<<request->getBillMoney()<<"RMB"<< endl;
        }else{
            successor->handleRequest(request);
        }
    }
};

class GeneralManager : public  Leader   //PM:Project manager项目经理
{
public:
    GeneralManager(string name):Leader(name){};
    void handleRequest(ShoppingRequest* request){
        if(request->getBillMoney()<200000.00){
            cout <<"总经理"<<name<<"处理物资采集:"<<
                 request->getShoppingReason()<<
                 ",批准采购资金为:"<<request->getBillMoney()<<"RMB"<< endl;
        }else{
            cout <<"董事会处理物资采集:"<<
                 request->getShoppingReason()<<
                 ",批准采购资金为:"<<request->getBillMoney()<<"RMB"<< endl;
        }

    }
};

int main()
{
    Leader* l1,* l2,* l3,* l4;
    l1=new Director("张三");
    l2=new DepartmentManager("李四");
    l3=new ViceManager("王五");
    l4=new GeneralManager("赵六");
    l1->setSuccessor(l2);
