數據庫的驅動配置出現錯誤:

舊版本的驅動配置:

<property name="driver" value="com.mysql.jdbc.Driver"/>
<property name="url" value="

jdbc:mysql://Localhost:3306/student?userUnicode=true&amp;characterEncoding=UTF-8

"/>

?mysql8.0的驅動配置
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf8&amp;useSSL=false&amp;serverTimezone=UTC&amp;rewriteBatchedStatements=true
