在使用spring boot操作数据库的时候,莫名其妙抛了一个错误:
ERROR o.a.tomcat.jdbc.pool.ConnectionPool - Unable to create initial connections of pool.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.
这个错误是因为mysql连接的依赖包是高版本的情况下:
mysql mysql-connector-java 6.0.6
在配置datasource.url时不能简单的这样配:
spring.datasource.url=jdbc:mysql://localhost:3306/chat
需要加上一些必要的后缀信息(改成下面的配置就可以了):
spring.datasource.url=jdbc:mysql://localhost:3306/chat?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
