SpringBoot连接mysql报错：java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized

• springboot的项目，今天启动时报了个异常：

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-8.0.19.jar:8.0.19]
	======== ............此处省略一万字............ ========

Process finished with exit code 0

• 异常分析：

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.

• 异常信息已经说的很明白了，大概是说时区不对，知道问题所在的话就好下手了

解决方法:：

1. 在连接mysql的URL中加上 serverTimezone=UTC

url: jdbc:mysql://localhost:3306/hotel?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC

2. 或者直接到mysql里执行语句 ：SET GLOBAL time_zone = '+8:00'
