SpringBoot連接數據庫的時候報錯

java.sql.SQLException: The server time zone value 'PDT' 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.

　　解決方案如下：

　　　　可以檢查數據庫版本和驅動的包是否適配，如果是mysql 8以上的版本，則需要驅動程序的版本與UTC時區配合使用，在JDBC連接中必須在連接字符串中明確指定serverTimezone。例如：

spring.datasource.url=jdbc:mysql://192.168.2.129:3306/test_db?useJDBCCompliantTimezoneShift=true&serverTimezone=UTC
