The server time zone value 'ÖÐ¹ú±ê×¼Ê±¼ä' 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.

具体异常信息如下：

java.sql.SQLException: The server time zone value 'ÖÐ¹ú±ê×¼Ê±¼ä' 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.

驱动包用的是mysql-connector-java-8.0.13.jar，新版的驱动类改成了com.mysql.cj.jdbc.Driver  
新版驱动连接url也有所改动；

spring:
      datasource:
        url: jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT%2B8

解决办法：需指定时区

//北京时间东八区
    serverTimezone=GMT%2B8 
    //或者上海时间
    //serverTimezone=Asia/Shanghai

PS：如果设置serverTimezone=UTC，连接不会报错，  
但是我们在用java代码插入到数据库时间的时候却出现了问题。  
e.g. 在Java代码里面设置的时间为：2018-11-27 17:35:51，但在数据库中保存的时间却是：2018-11-27 09:35:51，相差8个小时。原因是：UTC代表的是全球标准时间 ，而我们使用的是北京时区（即东八区时区），要领先UTC八个小时；
