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.
