3.报错的原因,因为我的application.properties文件连接MySql数据时，没有设置时间

#Spring datasource  连接数据库   
spring.datasource.url=jdbc:mysql://localhost:3306/qingfeng   #连接数据没有设置时间
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=qingfeng

4.把application.properties文件里面连接数据库里改成下面的

1 2	`#Spring datasource 连接数据库` `spring.datasource.url=jdbc:mysql://localhost:3306/qingfeng?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai #连接数据设置时间spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver spring.datasource.username=rootspring.datasource.password=qingfeng`

　　或者改为

#Spring datasource #连接数据设置时间spring.datasource.url=jdbc:mysql:

//localhost:3306/qingfeng?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&autoReconnect=truespring.datasource.driverClassName=com.mysql.cj.jdbc.Driverspring.datasource.username=rootspring.datasource.password=qingfeng

　改完了就可以了
