我将hibernate与spring mvc和Autowired Session工厂集成，如下面的编码

@Autowired
    private SessionFactory sessionFactory;


    @Override
    @Transactional
    public List<Usermaster> getUserList() {

        Session currentSession=sessionFactory.getCurrentSession();
        Query<Usermaster> theq=currentSession.createQuery("from Usermaster",Usermaster.class);
        List<Usermaster> user=theq.getResultList();
        // TODO Auto-generated method stub
        return user;
    }

但是收到如下错误：

我的servlet-context.xmlcoding是：

连接的所有细节都是正确的，项目运行正常，只有hibernate的错误，其中Usermaster是一个pojo文件，我该如何解决这个问题？

1 个答案:

答案 0 :(得分：0)

从Hibernate 4.3.x开始，JtaPlatform类被重构为一个新包。要解决此问题，请将Hibernate降级到4.2.x或更低版本，或者升级Spring框架。

在我的开发环境中测试过，这是适用的版本：

Spring 3.2.8.RELEASE Hibernate 4.2.11.Final

或

要修复它，您需要将spring版本升级到4.1.x最新版本.Below是pom.xml 

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.3.7.Final</version>
 </dependency>
 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>4.1.2.RELEASE</version>
 </dependency>
 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>4.1.2.RELEASE</version>
 </dependency>

您的依赖项中有哪个版本的Hibernate和Spring？
