Hibernate 4：org.hibernate.HibernateException：找不到當前線程的會話

我想使用Hibernate版本4.3.11.Final和Spring版本4.2.2.RELEASE。當我在我的UserDAO中獲得會話時，我有一個休眠異常：找不到當前線程的會話。我不明白你爲什麼可以幫助我？Hibernate 4：org.hibernate.HibernateException：找不到當前線程的會話

我下面的文件和資料來源：

謝謝

謝謝你的回答。我將org.springframework.jdbc.datasource.DataSourceTransactionManager更改爲org.springframework.orm.hibernate4.HibernateTransactionManager。但我總是有同樣的錯誤.. – user1364017

是的，我在TransactionManager配置中添加了這個：我在我的第一篇文章中更新了我的root-context.xml。感謝您的幫助 – user1364017

我總是有同樣的錯誤，我不明白爲什麼... – user1364017

好吧，我發現上的其他論壇的解決方案。我的包DAO，模型，服務必須由應用程序上下文（root-context.xml）掃描，而不是由servlet上下文（servlet-context.xml）掃描。所以我已經將下面的代碼從servlet-context更改爲root-context。

<bean id="userService" class="com.rg.flosite.service.UserServiceImpl"></bean> 
<bean id="userDao" class="com.rg.flosite.dao.UserDAOImpl"></bean> 
<tx:annotation-driven transaction-manager="transactionManager"/> 
<context:component-scan base-package="com.rg.flosite.dao" /> 
<context:component-scan base-package="com.rg.flosite.model" /> 
<context:component-scan base-package="com.rg.flosite.service" />
