相信很多小伙伴和我一样遇到了这类问题，在使用JDBC连接mysql数据库的时候发生SQLException如下所示的异常情况！
java.sql.SQLException: The server time zone value '¤¤°ê¼Ð·Ç®É¶¡' 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.

这其实是由于在安装的时候没有选择使用位置，mysql默认使用美国时间，所以得改成我们东八区的时间。
所以应该怎么做呢？
首先网上有很多方法是更改数据库中的 time_zone，如下图：
这个方法只能是解决这一次问题，重启之后依然会报错，还需要再次更改。
最好的方法就是在jdbc配置中添加?serverTimezone=UTC到末尾。
如下图所示：
