完美解决连接数据库启动报错：InvalidConnectionAttributeException: The server time zone value '�й���׼ʱ��' is unrecog

问题描述

在连接数据库进行操作的时候 启动项目 报了这么一个错误：

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

原因

服务器时区值无法辨认或表示多个时区 如果你想使用时区支持 你必须通过服务器时区配置属性来配置服务器或JDBC驱动从而使用更具体的时区值

简单来说 就是MySQL8.0及以上需要配置时区

解决方法

在配置文件的数据库url后面加上serverTimezone=Asia/Shanghai或是serverTimezone=UTC即可解决
