hibernate添加修改删除查询

  Student s = new Student();
  s.setId(8);
  s.setSname("卫江波");
  s.setSex("boy");
  s.setAge(24);
  s.setSchool("黑龙江科技大学");
  Configuration con = new Configuration().configure(); //  读取hibernate.cfg.xml配置文件
  SessionFactory factory = con.buildSessionFactory();//  通过hibernate.cfg.xml中的配置，创建SessionFactory
  Session session = factory.openSession();//  通过SessionFactory打开一个和数据库的会话
  Transaction tr = session.beginTransaction();//  通过Session开启事务
  tr.begin();

  session.save(s);//向数据库添加数据
  session.update(s);//修改

  session.delete(s);//删除

  tr.commit();//提交事务

  /*List studentList = null;
  String hql = "FROM Student";
  Query query = session.createQuery(hql);
  studentList = query.list();
  Iterator it = studentList.iterator();
  while(it.hasNext()) {
   Student temp = (Student) it.next();
   System.out.println(temp.getId()+"-->"+temp.getSname()+"-->"+temp.getSex()+"" +
     "-->"+temp.getAge()+"-->"+temp.getSchool());
  }*/

  List studentList = null;
  String hql = "FROM Student WHERE id=?";
  Query query = session.createQuery(hql);
  query.setInteger(0,6);
  studentList = query.list();
  Iterator it = studentList.iterator();
  if(it.hasNext()) {
   Student temp = (Student) it.next();
   System.out.println(temp.getId()+"-->"+temp.getSname()+"-->"+temp.getSex()+"" +
     "-->"+temp.getAge()+"-->"+temp.getSchool());
  }
//  关闭session
  session.close();

分页

page 为第几页，pagesize为一页显示多少个

Query query = getSession().createQuery(sql);
        query.setFirstResult((page - 1) * pagesize);
        query.setMaxResults(pagesize);

        return query.list();

String sql = "from Resource where owner.id = ?";
return getSession().createQuery(sql).setInteger(0, owner.getId().intValue()).list();
