今天在使用SpringBoot 链接数据库,测试得时候出现了以下错误:
Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

... 57 more报错原因:从报错信息可以看出来,是time-zone 的问题
解决办法: 所以我们在写数据库 database url 的时候
原来:
spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8
现在:
spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
加上 &serverTimezone=GMT%2B8 j即可
