Java 我收到了HibernateException“；没有绑定到线程的Hibernate会话，配置不允许在此创建非事务会话；

尽管这里有很多类似的问题，但似乎没有什么对我有用。调用sessionFactory.getCurrentSession（）.createQuery（“从字符串”）.list（）时会出现异常

以下是我的root-context.xml：

<context:component-scan base-package="org.vadim.testmvc.service"/>

<import resource="data.xml"/>

</beans>

hibernate.cfg.xml：

<?xml version='1.0' encoding='utf-8'?>

我将非常感谢您在这个问题上提供的一切帮助。

我认为问题的根源在于您没有通过接口访问您的服务。默认情况下，Spring使用基于Java接口的代理

顺便说一句，堆栈跟踪不包含任何事务性侦听器调用

参见文档下的第二个注释：

服务器上的代理目标类属性 元素控制为哪种类型的事务代理创建 用@Transactional注释注释的类。如果 代理目标类属性设置为true，则基于类的代理 创建。如果代理目标类为false或属性为 省略，创建标准的基于JDK接口的代理。（见 第7.6节“代理机制”，用于讨论不同 代理类型。）

因此，要么为事务服务和DAO引入接口，要么使用

proxy target class=“true”

这就是重点，感谢您的帮助！我刚刚为TestService和TestDAO添加了两个接口，这很有帮助！
