最近很多次遇到 The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone这个问题，
java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

后面的错误我就不列举出来了哈，
查阅了网上的资料，发现解决方法好多，但是这个其实是数据库中时间设置的问题
解决办法如下：
（1）首先我打开数据库终端后，输入 show variables like '%time_zone%';
(2)再进行时区设置，使用指令： set global time_zone='+8:00';
(3)再次运行自己的项目，你会发现这个问题解决了
