数据解析问题

[yueye410]

我用public来映射json数据，没设置get和set，后台返回空list时候，提示json数据格式化错误，有数据时候正常解析，这是为什么呢？🐶

贴一下。后台空数据和正常数据的大概模样

result里面的mycart，我也不知道是不是我哪里搞的有问题，谢谢。

成功的msgList返回的是List 失败msgList返回的对象。解析用的List



你觉得解析得出来不？

[Aries Hoo²⁰²¹]

同一个解析实体，返回的字段对应得都不是同一类型的解析肯定要报错

大佬这真是火眼金睛，我看了半天，特意测试了几个别的地方空数据，结果就这个出问题了，唉，谢谢。🙏
