SpringBoot 集成Mybatis--MySql报异常 java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä'

在SpringBoot中集成 Mybatis--Mysql时报异常：

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

            mysql-connector-java
            8.0.12
        
    

application.properties:

#config mysql info
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false

解决：

在application.properties配置mysql属性时，在spring.datasource.url中指定utc就行，具体如下：

spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC

网上查了下原因，说是mysql-connector-java版本更新引起的，有点道理 待有时间看下文档
