作者：大米宋
本文主要介绍了java报错Cause: java.sql.SQLException问题解决,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
问题描述：
Cause: java.sql.SQLException: The server time zone value ‘�й���ʱ��’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
持久化异常原因:java.sql.SQLException:服务器时区值’ йʱ’无法识别或代表多个时区。 如果希望利用时区支持，则必须(通过serverTimezone配置属性)配置服务器或JDBC驱动程序，以使用更特定的时区值。
报错原因：
这是jdbc连接url路径里面没有加时区；
解决办法：
mybatis.config.xml文件中url加入：
serverTimezone=Asia/Shanghai
<!--dataSource数据源-->
<dataSource type="POOLED">
<property name="driver" value="com.mysql.cj.jdbc.Driver"/>
<!--useSSL=true：就是一般通过证书或者令牌进行安全验证 useSSL=false：就是通过账号密码进行连接-->
<property name="url" value="jdbc:mysql://localhost:3306/mybatis?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=true"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</dataSource>
