学生业务逻辑接口实现

查询所有学生方法

public List<Student> queryAllStudent() {

Transaction transaction=null;

String hql="";

List<Student> list=null;

try{

Session session=MyHibernateSessionFactory.getSessionFactory().getCurrentSession();

transaction=session.beginTransaction();

hql="from Student";

Query query=session.createQuery(hql);

list=query.list();

transaction.commit();

return list;

}catch(Exception e){

e.printStackTrace();

return list;

}finally{

if(transaction!=null){

transaction=null;

}

}

}

test方法

@Test

public void testAddAllStudent(){

StudentDao sd=new StudentDaoImpl();

List<Student> studentList=sd.queryAllStudent();

for(int i=0;i<studentList.size();i++){

System.out.println(studentList.get(i));

}

}
