Spring 弹簧&x2B；冬眠+；WebFlow&x2B；专家无法使用@transactional从SessionFactory获取会话

我已经尝试了几乎一个星期的一切，但无法解决这个问题。当我使用sessionFactory.getCurrentSession（）时，我的会话不会自动创建（我的理解是这样的），因此我得到了异常。请帮我解决我的困难

我的刀

    @Component
public class DatingDAOimpl implements DatingDAO {

@Autowired
private SessionFactory sessionFactory;

public List<Dating> datings;


@Transactional
public List<Dating> getDatings() {

    datings = (List<Dating>) sessionFactory.getCurrentSession()
            .createCriteria(Dating.class)
            .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();

    return datings;
}

}

请帮我理解我的错误隐藏在哪里。提前感谢

我在会话中遇到了同样的问题。为了克服这个问题，我导入了org.hibernate.session，并在每个方法中调用了sessionFactory.getCurrentSession。希望这有帮助

@Transactional
@Repository("supplierDAO")
public class SupplierDAOImpl implements SupplierDAO {

public SupplierDAOImpl() {
}

@Autowired
private SessionFactory sessionFactory;

Session ss;

public SupplierDAOImpl(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

public List<Supplier> supplier() {
    ss = sessionFactory.getCurrentSession();
    return ss.createQuery("from Supplier").list();
}

@Transactional
@存储库（“供应商DAO”）
公共类SupplierDAOImpl实现SupplierDAO{
公共供应商daoimpl（）{
}
@自动连线
私人会话工厂会话工厂；
会话ss；
公共供应商DAOImpl（SessionFactory SessionFactory）{
this.sessionFactory=sessionFactory；
}
公开名单供应商（）{
ss=sessionFactory.getCurrentSession（）；
返回ss.createQuery（“来自供应商”）.list（）；
}

在pom.xml中，您正在使用hibernate v5，因此请更改以下内容：

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

您提到“当我使用sessionFactory.getCurrentSession（）时，我的会话没有自动创建（我的理解是这样的），因此我得到了异常。”您怎么会认为是这种情况？您能重新格式化您的异常吗，它很难读取。因为我使用方法“session.isConnected（）”检查它吗SeaStudio.OpSunStudio工作并被连接是正确的，但是GETCurrTeNeST在所有情况下都不起作用。我已经排除了您的异常，这似乎并没有表明您与DatingDaoImpl有任何问题。您可能没有捕捉到您的异常的真正原因，或者可能是问题在其他地方。请考虑编写GETDATION（）的单元测试。。它会很好地为您服务。当我使用事务性方法时，这两种方法都不起作用。如果没有事务性方法，openSession可以很好地工作，这是不可能的！当我按方法openSession创建会话时，一切都可以很好地工作，我可以从DB检索数据。但是SessionFactory.getStatistics（）向我显示0个打开的会话！这是怎么可能的？谢谢回答，但这并不能解决此问题。我已经导入了org.hibernate.session.Ok。谢谢。我将尝试使用服务重新创建我的应用程序。我喜欢你。但它甚至无法阻止try-catch，因为抛出错误。可能问题不在hibernate中，而是春天到了…好的，很好。现在记录异常应该很容易解决。这可能是因为您使用的hibernate版本。上传maven pom.xml文件，我们可以看到发生了什么。谢谢。我添加了pom.xml。今天我使用JTA的entityManagerFactory而不是hibernate的SessionFactory重新制作了项目。但是我的错误。。。
