我正在尝试将Spring应用程序从JBoss AS 4.0.5.GA迁移到7.1.1.Final。在我的jboss-spring.xml中有一个bean engine，其init方法导致下面的createQuery行被执行。
public class QueueConfigurationDAO {
private EntityManager _entityManager;
@PersistenceContext
public void setEntityManager(EntityManager entityManager) {
_entityManager = entityManager;
}
public List<QueueConfiguration> getQueueConfigurations() {
Query query = _entityManager.createQuery("from QueueConfiguration");
return query.getResultList();
}
}
这导致以下堆栈跟踪：

我认为QuerySyntaxException: QueueConfiguration is not mapped意味着我的
@javax.persistence.Entity
@javax.persistence.Table(name = "queue_configuration")
public class QueueConfiguration { /* ... */ }
类不被Hibernate识别为实体。实际上，当我在JBoss 4中运行应用程序时，启动日志包含像
这样的行INFO [org.hibernate.cfg.AnnotationBinder] Binding entity from annotated class: se.sunstone.workflow.queues.QueueConfiguration
但是当我尝试在JBoss 7中部署它时，日志中不会出现这样的行。如果我从engine注释掉jboss-spring.xml bean，那么应用程序会愉快地部署而没有例外。
我正在使用JBoss 7的内置Hibernate模块，而我正在使用Snowdrop模块部署我的webapp。我已经花了好几天了，包括尝试使用Hibernate 3，但问题仍然存在。
如果我在<class>se.sunstone.workflow.queues.QueueConfiguration</class>中明确指定persistence.xml，则应用程序将部署并且日志现在包含与在JBoss 4上运行时相同的AnnotationBinder行。但是，该应用程序还有一堆其他带注释的实体，其DAO在下面的配置中被省略，除非我在persistence.xml中指定它们，否则不会检测到它们。显然，AnnotationBinder不检测带注释的实体，除非我在persistence.xml中指定它们。那是为什么？
档案布局：
zz10-wf.spring
-- META-INF
---- jboss-deployment-structure.xml
---- jboss-spring.xml
---- jpa-persistence.xml
---- MANIFEST-MF
-- (Java package hierarchy)
关注these instructions我已将传统的persistence.xml重命名为jpa-persistence.xml，以便JBoss不会检测到它并启动自己的Hibernate实例。
zz10-wf.spring目前已部署为展开目录，但如果我将其部署为未压缩的zip存档，则会发生同样的情况。

我尝试在jpa-persistence.xml和entityManagerFactory bean定义之间来回移动配置详细信息，结果大致相同，并且应用程序同意使用此最小jpa-persistence.xml运行因为上面的QueueConfiguration行已取消注释。
答案 0 :(得分：1)
在这个问题的earlier incarnation中，我的一个问题是AnnotationBinder运行两次的原因。我认为这是因为JBoss检测到persistence.xml并且与Spring发起的实例并行启动了自己的Hibernate实例。在将persistence.xml重命名为jpa-persistence.xml（任何其他名称可能会执行此操作）之后，如in the JBoss AS 7 documentation所述，此行为已停止。但是，AnnotationBinder未检测到带注释的实体的问题仍然存在。
我从问题中编辑了这些问题，因为我希望问题更具体地说明为什么AnnotationBinder没有检测到带注释的实体。

请更新＆＃34; entityManagerFactory＆＃34; jboss-spring.xml中的bean如下：
示例（替换＆＃34; your_jpa_related_base_package＆＃34;与实际的一样）：
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<!--
<property name="persistenceXmlLocation" value="classpath*:META-INF/jpa-persistence.xml"/>
-->
<property name="dataSource" ref="dataSource"/>
