新添加代码344-348行和369行
1.运行客户端代码,需要注意的是把androidpn.properties中的xmppHost改为你的服务器ip地址
2.服务端 jdbc.properties修改mysql数据库连接
项目部署（服务器）
首先，我单独启动一个新的tomcat,将server端部署到这下面，修改配置文件config。properties,jdbc.properties。jdbc.properties这个文件是配置你本地数据库的参数的，不能有错。启动后，简单测试成功，在自己项目中使用http协议将数据POST到server端这个org.androidpn.server.console.controller.NotificationController类的send方法中。具体参数名称及获取参数的代码，可以修改server端。基本上，写到这里的话，应该可以满足项目需求了。如果你还需要将哪些用户在线的功能整合到你自己项目中。那你就得自己跟踪下代码了。
apiKey默认1234567890为了安全在config.properties里修改
NotificationController.java代码
