设计模式课程设计（抽象工厂模式，单例模式，代理模式）

设计模式课程设计：手机电脑商店

• 项目简介
• 抽象工厂模式
• 单例模式
• 代理模式

项目简介

  该项目运用了三种设计模式：抽象工厂模式，单例模式，代理模式。用户可以在商店里购买自己想要的手机和电脑。项目运行环境为Netbeans8.2。运行效果如下：

进入商店界面，这里运用了单例模式，不管怎么点击进入商店按钮，只会有一个窗体弹出

进入商店，用户可以选择自己要购买的东西。

用户购买成功

抽象工厂模式

抽象工厂：

package AbstractFactory;
public interface EFactory {public Phone producePhone();public Computer produceComputer();
}

抽象产品：

package AbstractFactory;
public interface Computer {public String produce ();
}

package AbstractFactory;
public interface Phone {public String produce();
}

具体工厂：

package AbstractFactory;
public class HuaWeiFactory implements EFactory {public HuaWeiFactory() {}public Phone producePhone() {return new HuaWeiPhone();}public Computer produceComputer() {return new HuaWeiComputer();}}

package AbstractFactory;
public class XiaoMiFactory implements EFactory {public XiaoMiFactory() {}public Phone producePhone() {return new XiaoMiPhone();}public Computer produceComputer() {return new XiaoMiComputer();}
}

具体产品：

package AbstractFactory;
import Agent.AgentFrame;
public class HuaWeiComputer implements Computer {public HuaWeiComputer() {}public String produce() {System.out.println("华为电脑生产中......");String str = "华为电脑生产中......";return str;}
}

package AbstractFactory;
import Agent.AgentFrame;
public class HuaWeiPhone implements Phone {public HuaWeiPhone() {}public String produce() {System.out.println("华为手机生产中......");String str = "华为手机生产中......";return str;}
}

package AbstractFactory;
import Agent.AgentFrame;
public class XiaoMiComputer implements Computer {public XiaoMiComputer() {}public String produce() {System.out.println("小米电脑生产中......");String str = "小米电脑生产中......";return str;}
}

package AbstractFactory;
import Agent.AgentFrame;
public class XiaoMiPhone implements Phone {public XiaoMiPhone() {}public String produce() {System.out.println("小米手机生产中......");String str = "小米手机生产中......";return str;}
}

单例模式

package company;import AbstractFactory.Computer;
import AbstractFactory.EFactory;
import AbstractFactory.HuaWeiComputer;
import AbstractFactory.HuaWeiFactory;
import AbstractFactory.HuaWeiPhone;
import AbstractFactory.Phone;public class HuaWeiCompany {private static HuaWeiCompany huaweiCompany = null;private RealHuaWei realhuawei = new RealHuaWei();private HuaWeiCompany() {}public static HuaWeiCompany getHuaweiCompany() {if (huaweiCompany == null) {huaweiCompany = new HuaWeiCompany();}return huaweiCompany;}public Phone getPhoneProducts() {return realhuawei.getPhoneProducts();}public Computer getComputerProducts() {return realhuawei.getComputerProducts();}
}

package company;import AbstractFactory.Computer;
import AbstractFactory.EFactory;
import AbstractFactory.HuaWeiComputer;
import AbstractFactory.HuaWeiFactory;
import AbstractFactory.HuaWeiPhone;
import AbstractFactory.Phone;
import AbstractFactory.XiaoMiComputer;
import AbstractFactory.XiaoMiFactory;
import AbstractFactory.XiaoMiPhone;public class XiaoMiCompany {EFactory factory;Computer computer;Phone phone;private static XiaoMiCompany xiaomiCompany = null;private RealXiaoMi realxiaomi = new RealXiaoMi();private XiaoMiCompany() {}public static XiaoMiCompany getXiaomiCompany() {if (xiaomiCompany == null) {xiaomiCompany = new XiaoMiCompany();}return xiaomiCompany;}public Computer getComputerProducts() {return realxiaomi.getComputerProducts();}public Phone getPhoneProducts() {return realxiaomi.getPhoneProducts();}}

代理模式

package company;
import AbstractFactory.Computer;
import AbstractFactory.Phone;
public interface Permission {public Phone getPhoneProducts();public Computer getComputerProducts();
}

package company;
import AbstractFactory.Computer;
import AbstractFactory.Phone;
public interface Permission_2 {public Phone getPhoneProducts();public Computer getComputerProducts();
}

package company;
import AbstractFactory.Computer;
import AbstractFactory.*;
import AbstractFactory.Phone;
public class RealHuaWei implements Permission {EFactory factory;Computer computer;Phone phone;public Phone getPhoneProducts() {factory = new HuaWeiFactory();phone = new HuaWeiPhone();phone.produce();return phone;}@Overridepublic Computer getComputerProducts() {factory = new HuaWeiFactory();computer = new HuaWeiComputer();computer.produce();return computer;}}

package company;
import AbstractFactory.*;
public class RealXiaoMi {EFactory factory;Computer computer;Phone phone;public Computer getComputerProducts() {factory = new XiaoMiFactory();computer = new XiaoMiComputer();computer.produce();return computer;}public Phone getPhoneProducts() {factory = new XiaoMiFactory();phone = new XiaoMiPhone();phone.produce();return phone;}
}
