java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more

springboot 2.1.1版本数据库连接不上，报了一个错误：

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.

网上查询了一下，这个是需要设置时区（大坑啊，之前不需要设置的），来设置一下：

url: jdbc:mysql://localhost:3306/mytest?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8

最后的serverTimezone=GMT%2B8就是时区设置。

设置完成之后就可以正常启动了！
完整的配置：

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/mytest?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8
    driver-class-name: com.mysql.cj.jdbc.Driver

注意com.mysql.cj.jdbc.Driver是mysql5.6以后版本的数据库驱动。
