极光推送（给手机端推送消息）

一、注册应用

1.去极光推送开发者服务网站注册账号

https://www.jiguang.cn/

2.注册完毕，登陆后创建应用

3.创建完毕获取应用信息

获取到appKey和masterSecret

*appKey是极光平台应用的唯一标识

*masterSecret是用于服务器端API调用时与appKey配合使用达到鉴权的目的

4.下载服务器端SDK（jar）

jiguang-common-1.0.8.jar

jpush-client-3.3.3.jar

gson-2.2.4.jar

log4j-1.2.17.jar

slf4j-api-1.7.7.jar

slf4j-log4j12-1.7.7.jar

将下载的jar包放入到lib下

后台Java实现（代码）
