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???????‘ 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
