java微信网页授权获取用户信息以及JSSDK自定义分享等功能<一>

博主采用的是eclipse+springmvc+jsp来做这一功能讲解。如控制器采用的是其他组件，原理一样，自己结合自己的实际环境来调整。

尊重原创，觉得有用多多推广，顺便给个赞。谢谢。

分三步：

第一，web.xml和applicationContext.xml的配置，如已掌握的童鞋，可自动忽略这节。

新建一个web工程，然后在src目录下新建一个applicationContext.xml文件

web.xm文件，源码在图片下方

整个工程目录如下：



项目引入jar包如下：这些是工程中用到的全部jar包，包括加解密，xml解析，springmvc等用到的全部jar包。如你的工程不需要则可以自行删除对应jar包。
