如何在JBoss Spring中使用JTA

Question

我正在通過休眠使用JTA，我有一個Ear文件，當我在glassfish中部署Ear文件時，它具有多個war文件，它運行正常，但是當我在Jboss中運行該Ear文件時，它給我一些錯誤

要使用JBOSS JTA，除了在<jta-data-source>之外，您不應該在persistence.xml配置任何內容。

要使用Spring應用程序中的JBOSS JTA，只需將其添加到配置中即可：

<tx:jta-transaction-manager/>

注意，最好允許將持久性單元提高到JBOSS：將persistence.xml放入jar的META-INF中。 從JNDI獲取entityManagerFactory ：

persistence.xml ：

<property name="jboss.entity.manager.factory.jndi.name" value="persistence/MY-UNIT"/>

application.xml

<jee:jndi-lookup id="emf" jndi-name="persistence/MY-UNIT"/>

<bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean"
          p:entityManagerFactory-ref="emf"/>

有了它，您可以繼續在服務中使用@PersistenceContext
