com.mysql.jdbc.Driver 是 mysql-connector-java 5中的
JDBC连接Mysql5 com.mysql.jdbc.Driver:
org.quartz.dataSource.qzDS.driver:com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL:jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=UTF-8
com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6中的
JDBC连接Mysql6 com.mysql.cj.jdbc.Driver， 需要指定时区serverTimezone:
#org.quartz.dataSource.qzDS.driver:com.mysql.cj.jdbc.Driver
#org.quartz.dataSource.qzDS.URL:jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
如果你用的mysql-connector-java 5，配置的是com.mysql.cj.jdbc.Driver的配置就会报java.lang.ClassNotFoundException: com.mysql.cj.jdbc.Driver这个错误。
如果你用的mysql-connector-java 6，配置的是com.mysql.jdbc.Driver的配置也会出现错误，总之MySQL版本要与其配置对应好。
