我正在接收HibernateException“No Hibernate Session绑定到线程，并且配置不允许在此创建非事务性的一个”。

本文介绍了我正在接收HibernateException“No Hibernate Session绑定到线程，并且配置不允许在此创建非事务性的一个”。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 尽管这里有很多类似的问题，但对我而言似乎没有什么用处。当我调用sessionFactory.getCurrentSession（）。createQuery（from Strings）。list（）;

} } 在这个问题上的每一个帮助。 解决方案我认为这个问题来自于你没有通过接口访问你的服务。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拦截器调用。 请参阅 Spring的这一段文档： $ b 元素上的proxy-target-class属性控制着什么类型的事务代理是为类创建的，这些类是用@Transactional注释注释的。如果 proxy-target-class属性设置为true，则基于类的代理将创建。如果proxy-target-class为false，或者如果省略了属性，则会创建标准的基于JDK接口的代理。 （见第7.6节代理机制讨论了不同的代理类型。） 因此，要么为您的事务服务和DAO引入接口，要么使用 proxy-target-class =true。 Despite the bunch of similar questions here nothing seems to be usefull to me.

By default, Spring uses Java interface-based proxies. BTW, the stack trace doesn't contain any transactional interceptor call.See the second note under this paragraph of the Spring documentation: The proxy-target-class attribute on the element controls what type of transactional proxies are created for classes annotated with the @Transactional annotation. If proxy-target-class attribute is set to true, class-based proxies are created. If proxy-target-class is false or if the attribute is omitted, standard JDK interface-based proxies are created. (See Section 7.6, "Proxying mechanisms" for a discussion of the different proxy types.)So, either introduce interfaces for your transactional services and DAOs, or use proxy-target-class="true". 这篇关于我正在接收HibernateException“No Hibernate Session绑定到线程，并且配置不允许在此创建非事务性的一个”。的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
