关于mysql解决报错java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or repre

今天在eclipse运行程序时候时，出现如下报错

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.

发现这是报的mysql系统时区的错误

解决方法：通过mysql命令行改回北京时区（东8区）

先查看mysql时区

输入 select curtime(); 和 show variables like "%time_zone%";

time_zone说明mysql使用system的时区。

接着输入 set global time_zone = '+8:00'; 和 set time_zone = '+8:00'; 以及flush privileges;

然后再次查看时区show variables like "%time_zone%";

再次运行程序就不会报这个错了
