jsp+ssh编程
@1f89f1d4这是内存地址
list.size() 0 就代表用户名和密码同时正确（username不能重复的情况）

初学jsp中的ssh框架
这么跟你说吧，SSH 是3个框架，一个是管和数据库打交道的，就是存数据，取数据的，是其中的H，即hibernate。
一个是管业务的，即struts2，也就是比如你在网页点一个按钮，后面应该给你显示那些数据，而这个时候，hibernate只管查，而怎么去查，是struts2管的。
一个是开源的框架，即spring，这个家伙主要是作用是依赖注入，说白点，就是你的程序里不需要出现任何常量，比如new Student() ,比如"hello" 等等 ，这些都可以靠配置文件来搞定了。
比如说你写了个字符串 ，是hello，后来你要改，要byebye了，如果没有依赖注入的话，你要去改程序的，打开程序，把hello改成byebye，这样的话就不好了，有了spring，你改个配置文件，搞定！具体怎么改的，在哪写的，这些我就不是一两句能说清楚了，而且我这也只是举个例子。
另外spring还给很多框架提供了支持，什么叫提供支持，就是spring里面有这些框架的支持类，你可以直接用，比如hibernate，就有这么一个类，hibernateDaoSupport，比如struts2，就有这么一个类ActionSupport。当然 还有其他很多现成的，写好的类给你用。
这就是叫提供支持！
我觉得我说的够白话了吧。
最后说说框架和设计模式，设计模式是一种设计的理念，说白点，设计模式就是模式，没有代码。
而框架，是已经写好的，具有一定功能的代码，框架一般都封装了很多现成的类，你可以直接使用，非常方便。
希望对你有帮助。

SSH问题:管理添加页面/web-root/jsp/admin/admin_insert.jsp代码如下：
在你的struts.xml中相应的action标签中加一属性method="insert"
action
method="insert"
attribute="adminForm"
input="/jsp/errors.jsp"
name="adminForm"
parameter="status"
path="/jsp/admin/admin"
scope="request"
type="org.lxh.myzngt.struts.action.AdminAction"
forward name="insertdo" path="/jsp/admin/admin_insertdo.jsp"/forward
forward name="list" path="/jsp/admin/admin_list.jsp"/forward
forward name="updatepwddo" path="/jsp/admin/admin_updatepwd_do.jsp"/forward
forward name="deletedo" path="/jsp/admin/admin_delete_do.jsp"/forward
/action
一般action都会继承ActionSupport，所以会默认执行excute方法，我们的逻辑处理一般会写在action中这个重写的方法内，你如果要用其他方法就需要在xml中说明
求一个jsp代码实现登录，验证消息就为用户名和密码
你是想用那种方法实现呢？ 是单单 jsp+javabean 还是 jsp+struts2 还是 ssh 框架？先给你个 jsp+struts2 的例子吧，我之前做过的，你只用看对你有用的部分
