Question

我整个上午都在敲打我的脑袋，以取代Infinispan的EHCache。我尝试了很多不同版本的配置。但似乎总是在Hibernate和Spring之间关于事务管理的缺失链接。为了我自己的耻辱，我不得不承认我似乎无法找到让这项工作一起工作的方法。

我正在使用由JPA和Hibernate（4.0.1）支持的Spring（3.1）的经典解决方案。随着EHCache成为第二级和查询缓存。全部部署在独立的Tomcat 7上。

有人在这里愿意为此分享一个有效的Spring配置吗？

非常感谢！

我包括Spring配置 - 如果某个地方存在明显缺陷......

对事务查找类使用org.hibernate.transaction.JBossTSStandaloneTransactionManagerLookup时出现异常。

添加依赖项后出现异常（随之而来的是很多间接依赖项）

我有类似的要求在Tomcat中运行jpa + l2 cache + infinispan。

以下的hibernate配置对我有用。

hibernate.cache.region.factory_class - ＆gt; org.hibernate.cache.infinispan.InfinispanRegionFactory hibernate.transaction.jta.platform - ＆gt; org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform hibernate.transaction.manager_lookup_class - ＆gt; org.hibernate.cache.infinispan.tm.HibernateTransactionManagerLookup

我有以下额外的依赖项。

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-infinispan</artifactId>
    <version>4.2.5.Final</version>
 </dependency>

<dependency>
    <groupId>org.jboss.jbossts</groupId>
    <artifactId>jbossjta</artifactId>
    <version>4.16.4.Final</version>
</dependency>

谁有Spring + Hibernate + 2LC Infinispan + JPA的工作示例？
