mac怎么设置ip地址映射

外观模式

public class Police {
    public void resgister(String name){
        System.out.println("公安系统注册："+name);
    }
}

public class School {
    public void assignSchool(String name){
        System.out.println(name+"学校报道");
    }
}

public class Social {
    public void handleSocial(String name){
        System.out.println("社保关系已转移");
    }
}

将以上三个部门组合成一个门面：

public class WeiXinFacade {
    Police police = new Police();
    School school = new School();
    Social social = new Social();

    public void handleAll(String name){
        police.resgister(name);
        school.assignSchool(name);
        social.handleSocial(name);
    }
}

也可为每一个部门单独提供方法
