Spring+JPA+MySQL的配置文件

一直在整合spring+hibernate，今天整合一下JPA +Spring

persistence.xml
默认放在 META-INF 目录下

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence persistence_1_0.xsd" version="1.0"> 
<persistence-unit name="java2000" transaction-type="RESOURCE_LOCAL">

<class>MyClass</class> 
<properties> 
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider" /> 
<property name="show_sql" value="true" /> 
<property name="hibernate.cache.use_second_level_cache" value="true" /> 
<property name="hibernate.cache.use_query_cache" value="false" /> 
</properties> 
</persistence-unit> 
</persistence>

<value>jdbc:mysql://localhost:3306</value>   后面需要指定databaseName吗?
