    3. import com.fasterxml.jackson.annotation.JsonIgnore;
    4. import com.fasterxml.jackson.databind.ObjectMapper;

    7.  * @author 
    8.  * @version V1.0
    9.  * @ Title: JSONResult.java
    10.  * @ Description: 自定义响应数据结构
    11.  * 本类可提供给 H5/ios/安卓/公众号/小程序 使用
    12.  * 前端接受此类数据（json object)后，可自行根据业务去实现相关功能
    13.  * 200：表示成功
    14.  * 500：表示错误，错误信息在msg字段中
    15.  * 501：bean验证错误，不管多少个错误都以map形式返回
    16.  * 502：拦截器拦截到用户token出错
    17.  * 555：异常抛出信息
    18.  * 556: 用户qq校验异常
    19.  * 557：校验用户是否在CAS登录（用户门票校验）
