com.mysql.jdbc.Driver 和 com.mysql.cj.jdbc.Driver

com.mysql.jdbc.Driver 是 mysql-connector-java 5中的，com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6中的

一、JDBC鏈接Mysql5 com.mysql.jdbc.Driver:

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false
username=root
password=

二、JDBC鏈接Mysql6 com.mysql.cj.jdbc.Driver， 須要指定時區serverTimezone:

driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
username=root
password=
