MySQL 8.x 新版本JDBC连接方式,旧版本,MySQL Connector/J 5.x 版本的连接方式,MySQL 8.x新版本,MySQL Connector/J 6.x之后 的连接方式,新版mysql驱动的url必须设置时区,即serverTimezone=UTC,否则会报错。 |
1.旧版本,MySQL Connector/J 5.x 版本的连接方式:
url = jdbc:mysql://localhost:3306/thrcloud_db01?useUnicode=true&characterEncoding=utf8 driver-class-name = com.mysql.jdbc.Driver
2、MySQL 8.x新版本,MySQL Connector/J 6.x之后 的连接方式:
url = jdbc:mysql://localhost:3306/thrcloud_db01?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false driver-class-name = com.mysql.cj.jdbc.Driver
注意:新版mysql驱动的url必须设置时区,即serverTimezone=UTC,否则会报如下错误:
Java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone.
