jfinal-weixin 用户授权登录

1：微信拦截器

2：微信授权登录

在AppConst.java定义一个常量

/*微信跳转页面 的session  key*/public static final String WX_REDIRECT_URL = "wx_redirect_url";

WechatConstants.java

public static final String AppId = "xxxx";public static final String AppSecret = "xxxx";public static final String token = "项目token换成自己的";public static final Boolean encryptMessage = false;public static final String encodingAesKey="setting it in config file";
