spring.net + Nhibernate 这个让我搞的头大的东西

spring.net + Nhibernate 做开发。大多数人会使用到HibernateTemplate。

我在看过spring.net 自带的例子，然后通过他的配置和方法，在访问数据调用的时候，HibernateTemplate 为null.

说明注入失败吗？
<?xml version="1.0" encoding="utf-8"?>

配置有错误吗？

public partial class _Default : System.Web.UI.Page
{
IPersonDAO personDAO;

public IPersonDAO PersonDAO
{

get { return personDAO; }

set { personDAO = value; }

}
protected void Page_Load(object sender, EventArgs e)
{

//Response.Write(message);
Response.Write(DMath.add(30, 50));




Person p = new Person();

p.Name = "Maruf";

personDAO.Save(p);

Person p1 = personDAO.LoadByID(1);



}
}

刚接触，所以有很多的不懂，望高手指点！
