枚举类型与前端交互出的错误

先来看一下接口的返回值

这是原来的返回值

FE小姐姐说status这个字段想要code和name,于是我改了一下

这是改之后的

期间爆了很多错

看了很多文章,试了很多方法,未果,直到看到一篇大佬的文章,贴上原文链接:https://blog.csdn.net/u011943534/article/details/105543879?utm_medium=distribute.pc_relevant.none-task-blog-blogcommendfrommachinelearnpai2-1.channel_param&depth_1-utm_source=distribute.pc_relevant.none-task-blog-blogcommendfrommachinelearnpai2-1.channel_param

最重要的就是这个

mybatis-plus.configuration.default-enum-type-handler=org.apache.ibatis.type.EnumOrdinalTypeHandler

2、返回的值不是我想要的,这返回的是枚举名

这个在enum上加一个注解就好@JsonFormat(shape =JsonFormat.Shape.OBJECT)

接下来贴上我代码:

enum类
bean
yml文件

大功告成!记录一下,希望可以帮到大家!
