多数据库的Spring数据jpa Spring事务

Question

我正在使用spring数据jpa为我的服务实现多事务（数据库），带有两个持久的单元名。并在Jboss 6.4 EAP中部署

<beans xmlns="http://www.springframework.org/schema/beans"

    <context:annotation-config />
    <tx:annotation-driven />
    <context:component-scan base-package="com.test.demo.domain.service" />
    <context:component-scan base-package="com.test.demo.domain" />
    <bean id="entityManagerFactory"
              class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="demo-domain" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"></bean>
        </property>
        <property name="persistenceProviderClass" value="org.hibernate.ejb.HibernatePersistence" />
    </bean>

    <bean id="entityManagerFactoryMeta"
              class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="demo-meta" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"></bean>
        </property>
        <property name="persistenceProviderClass" value="org.hibernate.ejb.HibernatePersistence" />
    </bean>
    <bean id="persistenceExceptionTranslationPostProcessor"
              class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
        <qualifier value="demoadmin"/>
    </bean>
    <bean id="transactionManagerMeta" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactoryMeta" />
        <qualifier value="demoappmeta"/>
    </bean>

    <jpa:repositories base-package="com.test.demo.domain.repository" />

</beans>

以下是我的服务详情

@Named(ServerConstants.SERVICE_DRAG_DROP)
**@Transactional("demoappmeta")**
public class DragDropService {
    private static final Logger LOG = LoggerFactory.getLoggerFactory().getDomainLogger(ServerConstants.LOGGER_DOMAIN, DragDropService.class.toString());

    @Inject
    private TbAsmiDragDropRepository dragDropRepo;

    public void createDragDrop(Message pMessage){
        JSONObject requestJson = pMessage.getRequestObject().getRequestJson();
        LOG.debug("inside createDragDrop() - Request : "+requestJson);

在Jboss中，我无法部署它，我遇到以下异常：

原因：org.springframework.beans.factory.BeanCreationException：无法自动装配字段：私有com.test.demo.domain.repository.TbAsmiDragDropRepositorycom.test.demo.domain.service.DragDropService.dragDropRepo；嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为“tbAsmiDragDropRepository”的bean时出错：调用init方法失败；嵌套异常是java.lang.IllegalArgumentException：不是托管类型：类com.test.demo.domain.entity.TbAsmiDragDrop

如果有什么遗漏或不对劲请告知

我找到了解决方案，只需在中设置属性实体管理器工厂ref=“entitymanagerfactoryrefname”

<jpa:repositories base-package="com.test.demo.domain.repository" entity-manager-factory-ref="entitymanagerfactoryrefname" />
