如何解决此问题“未找到查询类的持久类”信息？

Question

我正在使用 zkoss 5.0.4、Spring 3.0.3、Hibernate 3 和 JpA 1.0 以及 JBOSS 5.1 GA（支持 JDK）创建一个 Web 应用程序。

该项目使用 JBOSS 编译得很好。但由于某种原因，坚持似乎并不适用。

当我在控制台中运行应用程序时，它会显示以下内容：

10:07:35,265 WARN  [QuerySplitter] no persistent classes found for query class: from org.zkforge.zktodo2.Reminder

如果您需要我提供的其他内容，请告诉我。

Answer 1

我在持久性文件中添加了以下内容，并且开始正常。

< class >org.zkforge.zktodo2.Reminder< / class >

添加上面的行在数据库中创建了表，并且持久性错误消失了。

我不知道为什么我们需要添加它。有什么理由吗？ Spring 或 Hibernate 不应该从 Reminder.java 文件中获取该内容吗？

Answer 2

对我来说，错误的 sessionFactory 配置 packagesToScan 导致了问题

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

    ....
<!-- package was incorrect here -->
<property name="packagesToScan" value="com.foo.test.bean"/>

Answer 3

日志文件有以下内容：

10:06:41,375 警告 [Ejb3Configuration] 持久性

提供者调用者没有实现
EJB3 规范正确。
PersistenceUnitInfo.getNewTempClassLoader()
为空。 10:06:41,515 信息
[AnnotationBinder] 绑定实体
带注释的类：
org.zkforge.zktodo2.提醒

我认为你应该重新看看Reminder类。
