静态代理

package com.test.staticProxy;public interface IUsersService {public void insert();
}

package com.test.staticProxy;//目标类
public class UsersService implements  IUsersService {@Overridepublic void insert() {System.out.println("添加用户");}
}

package com.test.staticProxy;import java.util.Date;//代理类
public class UsersServiceProxy implements  IUsersService {//在代理类中存放一个目标类对象private IUsersService usersService=new UsersService();@Overridepublic void insert() {System.out.println("添加开始前:"+new Date());usersService.insert();System.out.println("添加结束后:"+new Date());}
}

测试

package com.test.staticProxy;import org.junit.Test;public class TestStaticProxy {@Testpublic void test(){IUsersService usersService=new UsersServiceProxy();usersService.insert();}
}
