spring boot 项目整合myba报错 java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized

spring boot 项目报错 java.sql.SQLException: The server time zone value ‘�й���׼ʱ��’ is unrecognized，翻译解说原文是时区不对

报错根源在于mysql-connection-java版本太高导致时区问题。

报错代码：

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.

	。。。。。

解决方式1

加上 mysql-connector-java 较低的版本号如：5.1.47，如果加上版本号6.0.6也不行，可能是因为版本太高。

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<version>5.1.47</version>
	<scope>runtime</scope>
</dependency>

解决方式2

不加版本号或者版本号为6以上，解决方式：在连接数据库的配置文件中加上以下，时区亚洲/上海
方式一：

jdbc:mysql://127.0.0.1:3306/maven?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

方式二：

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/maven?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC

解决方式3（暂未验证）
