我正在 FUSE 服务器上进行 Hibernate 的简单演示，我在这个github 位置找到了这个示例代码示例。我尝试在带有 Hibernate 4 集成的 FUSE 6.3 中运行此代码，我能够安装所有必需的依赖项，但是当我尝试执行数据库操作时，出现以下错误。

这是我的 StudentImpl.java 文件内容。
package com.vcc.poc.dao.impl;
import java.util.List;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.hibernate.internal.SessionImpl;
import com.vcc.poc.dao.StudentDao;
import com.vcc.poc.model.Student;
public class StudentDaoImpl implements StudentDao{
private static final transient Log LOG = LogFactory.getLog(StudentDaoImpl.class);
/** The session factory. */
private SessionFactory sessionFactory;
/** The q. */
private Query q = null;
/** The Constant findStudentByReference. */
private final static String findStudentByReference =
"select i from Student as i where i.studentRef = :ref";
/** The Constant findStudent. */
private final static String findStudent =
"select i from Student as i";
/**
* Sets the session factory.
*
* @param sessionFactory the new session factory
*/
public void setSessionFactory( SessionFactory sessionFactory )
{
this.sessionFactory = sessionFactory;
}
/*
* (non-Javadoc)
* @see org.apache.camel.example.reportincident.dao.IncidentDAO#findIncident()
*/
public List<Student> findStudent()
throws HibernateException
{
// Prepare query
q = this.sessionFactory.getCurrentSession().createQuery( findStudent );
// Retrieve the Incidents from database
List<Student> list = q.list();
return list;
}
/*
* (non-Javadoc)
* @see org.apache.camel.example.reportincident.dao.IncidentDAO#getIncident(long)
*/
public Student getStudent(int id)
{
return (Student) this.sessionFactory.getCurrentSession().get( Student.class, id );
}
/*
* (non-Javadoc)
* @see org.apache.camel.example.reportincident.dao.IncidentDAO#saveIncident(org.apache.camel.example.reportincident.model.Incident)
*/
public void saveStudent(Student Student)
{
SessionImpl session = (SessionImpl) this.sessionFactory.getCurrentSession();
this.sessionFactory.getCurrentSession().saveOrUpdate( Student );
}
}
根据下面的异常是它抛出异常的行
return (Student) this.sessionFactory.getCurrentSession().get( Student.class, id );
这是我在 META-INF/spring 文件夹中的 data-source-beans.xml

这是我的项目结构。
有没有人在 FUSE hibernate 集成中遇到过这种问题。我能够毫无问题地安装项目。但是，当我尝试执行数据库操作时，我会收到此错误。
请一些专家帮助我解决这个问题。
