我重构了我的服务层以作为通用组件工作。之后，我的控制器的所有请求都开始抛出org.hibernate.HibernateException：没有Hibernate Session绑定到线程，并且配置不允许在这里创建非事务性的。
我在互联网上搜索并找到了常见的原因：
但似乎没有一个与我的案件有关。
我很感激任何帮助，因为我花了这么多时间来处理这个例外。

我似乎发现了自己的错误。
root-context.xml和servlet-context.xml都包含相同的行<context:component-scan base-package="ru.centr_in.rescuer.server" />。
现在我按以下方式指定了基础包：
<强>根context.xml中
<context:component-scan base-package="ru.centr_in.rescuer.server.service" />
<context:component-scan base-package="ru.centr_in.rescuer.server.dao" />
和 servlet-context.xml
<context:component-scan base-package="ru.centr_in.rescuer.server.web" />
现在一切正常。

Spring建议您只使用@Transactional注释来注释具体类（以及具体类的方法），而不是注释接口。
您是否尝试将@Transactional注释放在InfoJournalServiceImpl课程上？另外，您是否检查过弹簧配置中有<tx:annotation-driven transaction-manager="..." />，如the Spring documentation中所述？
