删除学生资料

一：界面调用

<td><a href="<%=path %>/students/Student_delete?sid=<s:property value="#stu.sid"/>" onclick="javascript: return confirm('确认删除吗？');">删除</a></td>

二：编写业务逻辑代码

public boolean deleteStudent(String sid) {

// TODO Auto-generated method stub

Transaction transaction=null;

try{

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

Student stu=(Student)session.get(Student.class, sid);

session.delete(stu);

transaction.commit();

return true;

}catch(Exception e){

e.printStackTrace();

return false;

}finally{

if(transaction!=null){

transaction=null;

}

}

}

三：编写删除action

public String delete(){

String sid=request.getParameter("sid");

sd.deleteStudent(sid);

return "student_delete_success";

}

四：测试

    <result name="student_delete_success" type="chain">Student_query</result>
