Question

我需要将hibernate与spring集成在一起，并且必须使用HibernateTemplate来执行数据库操作。但是它抛出异常。

Exception in thread "main" java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;
at org.springframework.orm.hibernate3.SessionFactoryUtils.doGetSession(SessionFactoryUtils.java:319)
at org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(SessionFactoryUtils.java:235)
at org.springframework.orm.hibernate3.HibernateTemplate.getSession(HibernateTemplate.java:470)
at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:405)
at org.springframework.orm.hibernate3.HibernateTemplate.executeWithNativeSession(HibernateTemplate.java:374)
at org.springframework.orm.hibernate3.HibernateTemplate.save(HibernateTemplate.java:694)
at com.shubham.SpringHibernateAssignment.StudentDAO.saveStudent(StudentDAO.java:19)
at com.shubham.SpringHibernateAssignment.App.main(App.java:26)

在以下代码中找到 StudentDAO.java 类的代码，该类使用HibernateTemplate执行数据库操作。

public class StudentDAO   {
     HibernateTemplate template;  
      public void setTemplate(HibernateTemplate template) {  
          this.template = template;  
    }

    public void saveStudent(Student stud){


    template.save(stud);
    }

    public Student getById(int id){  
           Student e=(Student)template.get(Student.class,id);  
           return e;  
    }  

    public List<Student> listAll(){  
        List<Student> list=new ArrayList<Student>();  
        list=template.loadAll(Student.class);  
        return list;  
    }  

}

这是配置文件-applicationContext.xml
