MySQL Connector/J 6.x jdbc.properties 配置, mysql-connector-java-6.0.4.jar 异常

报错信息

Caused by: com.mysql.cj.core.exceptions.InvalidConnectionAttributeException: The server time zone value '�й���׼ʱ��' 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.

出现原因：

因为使用了Mysql Connector/J 6.x以上的版本，然后就报了时区的错误

解决方案：

### MySQL Connector/J 5.x   (旧版连接)
#jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8
### MySQL Connector/J 6.x   (新版连接)
jdbc.url=jdbc:mysql:///test?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false

于此同时，驱动也建议使用新版驱动

#数据库驱动

### MySQL Connector/J 5.x   (旧版连接

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

### MySQL Connector/J 6.x   (新版连接)
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
