一、问题描述

org.h2.jdbc.JdbcSQLSyntaxErrorException:  Table "EP_MAPPING" not found (this database is empty);

大概就是说在引入mybatis-plus的依赖后，找不到数据库找不到表的问题。
排查方向：在引入mybatis+h2时，是可以正常运行的，但是改为mybtis-plus后，报错找不到tables。按理说，mybatis-plus集成了mybatis，一般不会出现这样的问题。
排查结果：版本问题，不兼容。
springboot 2.7.x
mybatis-plus 3.5.3.2
h2内嵌在springboot parent里边
