通过JTA配置Spring + Hibernate JPA事务管理器

我以前使用RESOURCE-LOCAL事务类型为Hibernate配置了这个配置:

的persistence.xml:

<persistence-unit name="myPU" transaction-type="JTA">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

</persistence-unit>

applicationContext(dataaccess bit):

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" p:entityManagerFactory-ref="entityManagerFactory"></bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jpaVendorAdapter" ref="jpaAdapter" />
    <property name="persistenceUnitName" value="myPU"/>
    <property name="jpaProperties">
        <props>
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

<bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.jpa.vendor.HibernateJpaSessionFactoryBean">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
    <!-- Are there any other properties required? -->
</bean>

<bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">

    <property name="showSql" value="true" />
    <property name="generateDdl" value="false" />
</bean>

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/CNTXESDB" />
    <property name="lookupOnStartup" value="true" />
    <property name="cache" value="true" />
    <property name="proxyInterface" value="javax.sql.DataSource" />
</bean>

但是这种交易似乎不适用于Glassfish,所以我不得不切换到JTA交易。

问题是 - 让Spring管理事务创建(通过@Transactional)我需要定义一个TransactionManager bean但是spring-tx中包含的JtaTransactionManager不接受entityManagerFactory bean,所以它不知道entityManager在哪里打开/关闭/刷新Hibernate会话。

那么如何使用Hibernate配置Spring来使用JTA事务呢?

修改 事实证明可以使用与Glassfish的RESOURCE_LOCAL事务,但不知何故,您不能拥有persistence.xml文件。我将此文件重命名为my_persistence.xml并配置LocalContainerEntityManagerFactoryBean,如下所示:

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter" ref="jpaAdapter" />
        <property name="persistenceUnitName" value="myPU"/>
        <property name="persistenceXmlLocation" value="classpath:META-INF/my_persistence.xml" />
        <property name="jpaProperties">
            <props>
                <prop key="javax.persistence.validation.mode">none</prop>
            </props>
        </property>
    </bean>

我有类似的问题,最后我解决了你在这个小小的演示中看到的: https://github.com/miguelangelprogramacion/spring4_jpa_hibernate

以[1]作为参考,我更喜欢在JTA之前使用Spring的事务支持。

另外,我使用了基于注释的方法。
