问题描述

我不得不将Spring WebFlow项目更新为Spring 3.1，而Hibernate 4则试图让Maven工作。它看起来像一切正在工作，但在项目的一部分将做数据库读取我得到以下错误：

I had to update my Spring WebFlow project to Spring 3.1 and Hibernate 4 do to trying to get maven to work. It looks like everything is working now but at the part of the project going to do a database read I get the following error:

org.hibernate.HibernateException: No Session found for current thread   org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97)

我不知道为什么我在hibernate3中没有得到这个错误，但有人可以告诉我如何解决这个问题。

I dont know why I did not get this error in hibernate3 but can someone please tell me how to fix this.

这是我的pom.xml

推荐答案

尝试将其添加到您的服务中：

Try to add this to your service:

@Transactional(readOnly=true, propagation=Propagation.REQUIRED)
