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

报错说是时区不对

因为mysql-connection-java版本导致时区的问题。

pom.xml:

控制台报错信息：
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. at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129) ~[mysql-connector-java-8.0.16.jar:8.0.16]

解决方式1
加上版本号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>mysqlgroupId>
			<artifactId>mysql-connector-javaartifactId>
			<version>5.1.47version>
			<scope>runtimescope>
		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

url: jdbc:mysql://localhost:3306/mydb?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

解决方式3
