最近遇到一个问题，本地调试代码没问题提交部署有问题。只能吧错误日志打印出来看看发现问题如下

系统内部错误: org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database. Cause: java.lang.reflect.InaccessibleObjectException:

发现是mybatis方法，经过一通查发现可能是jdk版本的问题遂给本地代码切换了jdk版本原先是1.8，改为17，成功引出问题。

问题根源

看来是mybatis和jdk17组合出问题了，继续查mybatis
