一直在整合spring+hibernate今天整合一下JPA +Spring
persistencexml 默认放在 METAINF 目录下
Xml代码
<persistence xmlns= xmlns:xsi=instance
xsi:schemaLocation= persistence__xsd version=>
<persistenceunit name=java transactiontype=RESOURCE_LOCAL>
<provider>orghibernateejbHibernatePersistence</provider>
<class>MyClass</class>
<properties>
<property name=hibernatecacheprovider_class value=orghibernatecacheEhCacheProvider />
<property name=show_sql value=true />
<property name=hibernatecacheuse_second_level_cache value=true />
<property name=hibernatecacheuse_query_cache value=false />
</properties>
</persistenceunit>
</persistence>
