我正在對FUSE服務器上的Hibernate進行簡單演示，並在此github location中找到了此示例代碼示例。 我嘗試在HUSE 4集成的FUSE 6.3中運行此代碼我能夠安裝所有必需的依賴關係，但是當我嘗試執行數據庫操作時遇到以下錯誤。FUSE hibernate應用程序爲當前線程異常拋出沒有會話

這是我的StudentImpl.java文件內容。
package com.vcc.poc.dao.impl;
import java.util.List;

public class StudentDaoImpl implements StudentDao{
private static final transient Log LOG = LogFactory.getLog(StudentDaoImpl.class);
/** The session factory. */

this.sessionFactory = sessionFactory;
}

public List<Student> findStudent()
throws HibernateException
{

// Retrieve the Incidents from database
List<Student> list = q.list();
return list;
}
/*

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);
}
}
根據下面的例外是線就拋出異常
return (Student) this.sessionFactory.getCurrentSession().get(Student.class, id);
這是META-INF/spring文件夾在我的數據源的beans.xml

這是我擁有的項目結構。
有誰經歷過這種問題對FUSE Hibernate集成。我能夠安裝項目沒有任何問題。但是，當我嘗試執行數據庫操作時，我得到這個錯誤。
請高手幫我解決這個問題。
