SpringBoot配置JDBC连接MySql报错:HikariPool-1 - Exception during pool initialization

使用SpringBoot做JAVA开发时,JDBC连接MySql数据库的时候遇到了报错:

ERROR 10392 --- [           main] com.zaxxer.hikari.pool.HikariPool        : HikariPool-1 - Exception during pool initialization.

WARN 10392 --- [           main] o.s.b.a.orm.jpa.DatabaseLookup           : Unable to determine jdbc url from datasource

WARN 10392 --- [           main] o.h.e.j.e.i.JdbcEnvironmentInitiator     : HHH000342: Could not obtain connection to query metadata : 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.

1.首先检查了数据库账号密码是否正确:正确无误;

2.再检查数据库的访问权限: IP:%(所有人)的访问权限;

3.最后想到会不会是时区的问题,所以给application.yml文件中的datasource配置节中的url配置加上&serverTimezone=UTC(如下图),发现问题被解决。

这是原配置:
