springboot项目连接数据库报错

　　学习SpringBoot也没有多久，今天SpringBoot连接数据库的时候报如下错误：

java.sql.SQLException: 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.

　　　　我们用mavean加载mysql驱动包的时候，一般如下加载的：

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

            <version>6.0.5</version>

        </dependency>

但是我们使用springboot框架来编写程序就会报错误，并且在pom.xml中也会有相关提示：

springboot项目连接数据库报错

解决方案：我把mysql的版本号去掉就可以正常运行了。
