jpa整合spring
首先引入该引入的包
最重要的就是beans.xml的配置
附上
<?xml version="1.0" encoding="UTF-8"?>

<!-- 使用数据源和指定persistence.xml位置的方式创建entityManagerFactory,如果使用的不是hibernate JPA实现,
需要在tomcat作一些特殊配置.具体参考手册
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
<context:property-placeholder location="classpath:jdbc.properties"/>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

还有persistence.xml中的配置
<?xml version="1.0"?>

xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
