休眠 无法获取当前线程的事务同步会话

我一直遇到与许多人类似的问题，但我似乎无法弄清楚在我的特定情况下出了什么问题。我正在进行一个简单的数据库调用来测试数据库连接，而Hibernate正在引发以下异常：

Exception in thread "main" org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:134)
at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:1014)
at boardwalk.computeServer.dao.DbDaoHibernateImpl.getInterpolationJob(DbDaoHibernateImpl.java:73)
at boardwalk.computeServer.ComputeServer.test(ComputeServer.java:39)
at boardwalk.computeServer.ComputeServer.main(ComputeServer.java:32)

以下是相关代码和配置：

Hibernate DAO（为了清楚起见，映射对象已被省略，因为我认为它们不是导致问题的原因，因为在可以使用任何一个对象之前会引发异常）：

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.dao.DataAccessException;

import boardwalk.computeServer.data.InterpolationDesiredPoint;
import boardwalk.computeServer.data.InterpolationJob;

public class DbDaoHibernateImpl implements DbDao {

    private final SessionFactory sessionFactory;

    public DbDaoHibernateImpl(SessionFactory sessionFactory){
        // Save the session factory
        this.sessionFactory = sessionFactory;
    }


    @Override
    public InterpolationJob getInterpolationJob(int jobId) {

        // Get the session
        Session s = sessionFactory.getCurrentSession();

        // Load the object from the database and return it
        return (InterpolationJob) s.get(InterpolationJob.class, jobId);

    }

}

主类：

import org.apache.log4j.Logger;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.transaction.annotation.Transactional;

import boardwalk.computeServer.dao.DbDao;

public class ComputeServer {

    private static final Logger LOG = Logger.getLogger(ComputeServer.class);

    /**
     * Runs the server
     * @param args none
     */
    public static void main(String[] args) {

        // Create the application context
        @SuppressWarnings("resource")
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring/beans.xml");
    context.registerShutdownHook();

        // Log the server start
        LOG.info("Server has started");

        test(context);
    }


   @Transactional
   public static void test(ClassPathXmlApplicationContext context){
      DbDao dao = (DbDao) context.getBean("dbDao");
      System.err.println(dao.getInterpolationJob(1));
   }

}

我应该注意，当我用“openSession（）”替换“getCurrentSession（）”时，程序运行良好。

提前感谢您！
