Spring-Boot 2.0启动Mysql报时区错误

• 原因：安装mysql的时候时区设置的不正确，Mysql默认的是美国的时区，而我们中国大陆要比他们迟8小时，采用+8:00格式，导致数据库和系统时区差异。

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

• 解决办法：
  1. 修改Mysql配置文件my.ini

  2. 重启Mysql服务

     net stop mysql  停止当前mysql服务
     net start mysql 重新启动mysql服务
     

  3. 查看修改后的时区value不再显示System,为修改后的+08:00

      show variables like '%time_zone%';
