解决项目部署到服务器时mybatis报错

 记录一次mybatis的错误：

项目在本地跑没有任何问题，部署到服务器上之后报错如下：

错误原因：

版本问题

解决方法：

jdbc.url=jdbc:mysql://localhost:3306/djcheck?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true

jdbc.username=root

jdbc.password=root

划重点：

&serverTimezone=UTC&rewriteBatchedStatements=true
