androidpn和smack的关系与使用上的差别

一、两者的关系

androidpn server中引用了smack的部分代码，jar包的名字是 tinder-1.2.1.jar

在androidpn 客户端使用了asmack，在服务器端androidpn 自己封装了Xmpp协议，在一些地方使用了tinder(也就是smack),tinder和smack的差别在其他文章中说明。

二、两者使用上的差别

smack使用自己的connection建立socket监听和连接。

androidpn使用mina作为数据接入的方式。

三、spring与mina整合的配置文件

通过Spring与mina的整合，建立了以 mina的NioSocketAcceptor 做为入口，以handler为出口的mina环境。

之后的逻辑都是同handler 开始的。
