spring boot mybatis 枚举错误
- 今天遇到一个问题，解决了好几个小时，没有搞定，搞到现在，有大佬可以帮我看下吗？万分感谢，没有分了，枚举映射，在idea中可以使用， 部署使用java -jar 方式就报错
- jdk1.8
- mybatis3.0.7.1
- application.yml环境为prod
mybatis-plus: #枚举 typeHandlersPackage: com.xxx.common.module.handler查询代码，不能转换
public LsAppEntity queryByAppKey(String appKey) { return this.getOne(new QueryWrapper<LsAppEntity>() .eq("app_key", appKey) .ne("status", StatusEnum.删除)); }
