代理模式（静态以及动态）
代理接口：

package ProxyPattern;public interface Italk {public void talk(String msg);}

RealSubject：

package ProxyPattern;public class People implements Italk {public String username;public String age;public String getName() {return username;}public void setName(String name) {this.username = name;}public String getAge() {return age;}public void setAge(String age) {this.age = age;}public People(String name1, String age1) {this.username = name1;this.age = age1;}public void talk(String msg) {System.out.println(msg + "!你好,我是" + username + "，我年龄是" + age);}}

代理类：

package ProxyPattern;public class TalkProxy implements Italk {Italk people;public TalkProxy(Italk people) {this.people = people;}public void talkProxy(Italk people) {this.people = people;}public void talk(String msg) {people.talk(msg);}public void talk(String msg, String singname) {people.talk(msg);sing(singname);}private void sing(String singname) {System.out.println("唱歌：" + singname);}}

测试：

package ProxyPattern;public class MyProxyTest {public static void main(String[] args) {People people1 = new People("湖海散人", "18");people1.talk("No ProXY Test");System.out.println("-----------------------------");TalkProxy talker = new TalkProxy(people1);talker.talk("ProXY Test", "七里香");}}

另外一种代理模式：
动态代理：

package Dybamic;import java.lang.reflect.InvocationHandler;import java.lang.reflect.Method;public class Handler implements InvocationHandler {public Object targetObj;public Handler(Object targetObj) {this.targetObj = targetObj;}@Overridepublic Object invoke(Object proxy, Method method, Object[] args)throws Throwable {System.out.println("before the function "" + method.getName() + """);Object ret = method.invoke(targetObj, args);System.out.println(ret);System.out.println("after the function "" + method.getName() + """);return ret;}}

动态代理测试：

package ProxyPattern;package Dybamic;import java.lang.reflect.Proxy;public class testMain {public static void main(String[] args) {IUser realUser = new UserImp("sun");Handler hand = new Handler(realUser);IUser proxy = (IUser) Proxy.newProxyInstance(realUser.getClass().getClassLoader(), realUser.getClass().getInterfaces(), hand);proxy.getName();}}
