Spring mvc + hibernate + maven

-2

我是spring mvc和hibernate的新手。为了帮助我理解我遵循本教程http://viralpatel.net/blogs/spring3-mvc-hibernate-maven-tutorial-eclipse-example/ 我收到了这个错误org.hibernate.HibernateException：找不到当前线程的会话。我已经将事务管理器和@transaction包含在服务实现和dao中。请在下面找到Spring mvc + hibernate + maven

错误日志中的错误和代码片段：

请格式化代码。您可以选择多行，然后单击{}按钮以获得格式化的部分。您也可以取出pom.xml文件，保留异常堆栈跟踪的前8-10行。 – gkamal

取消注释此行Spring配置文件，它应该工作。没有这个@Transactional注释被忽略。你在开始的标签来自mvc命名空间（在你的情况下是默认命名空间） - 其目的与此不同。所以你需要有两个。

<!-- <tx:annotation-driven /> -->

+1这应该有所斩获。有关此Spring事务配置的文档，请参阅本文档的第13.3.3节（http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm）。 HTML＃ORM眠）。 –
