连接mysql数据库报错java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized...解决方法

　　今天连接mysql数据库报错如下：

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.

配置文件中：

######数据库链接配置########
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/aa
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

解决方法：

修改配置文件内容：

######数据库链接配置########
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/aa?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

在配置 spring.datasource.url 的时候加上后面的配置就可以了
