    注意:使用该方式需要把persistence.xml中的hibernate.connection.driver_class,hibernate.connection.username,hibernate.connection.password,hibernate.connection.url配置删除

jdbc.properties

driverClassName=org.gjt.mm.mysql.Driver
url=jdbc:mysql://localhost:3306/itcast?useUnicode=true&characterEncoding=UTF-8
username=root
password=root
initialSize=1
maxActive=100
maxIdle=8
minIdle=1

       通过spring来管理数据源，jdbc.properties文件的链接信息避免和persistence.xml文件冲突造成错误，注释或删除persistence.xml的链接部分。
