Spring 数据 jpa + Spring 事务用于多个数据库

Question

我正在使用带有@Transaction的 spring data jpa 为我的服务实现多个事务(数据库)，具有两个持久的单元名称。并在 Jboss 6.4 EAP 中部署

春季 XML 包括

<bean id="entityManagerFactoryMeta"

<property name="persistenceUnitName" value="demo-meta" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"></bean>

<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，我得到以下异常：

原因：org.springframework.beans.factory.BeanCreationException： 无法自动连线字段：专用 com.test.demo.domain.repository.TbAsmiDragDropRepository com.test.demo.domain.service.DragDropService.dragDropRepo;嵌 套 exception is org.springframework.beans.factory.BeanCreationException： 创建名为"tbAsmiDragDropRepository"的 Bean 时出错：调用 的初始化方法失败;嵌套异常是 java.lang.IllegalArgumentException： 不是托管类型： class com.test.demo.domain.entity.TbAsmiDragDrop

如果缺少任何内容或错误，请告知

我找到了解决方案，只是我们必须在

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