1.1自定义框架总结
1.1版本的自定义框架
首先在Hibernate的基础下,将多个Servlet合并成了一个ServletAction,此时ServletAction只负责做判断调用对应的Action类,Action类则负责从jsp页面拿值处理调用Biz,并返回调用的下一个jsp页面给ServletAction做出对应的处理.

以登录为例子
ServletAction
public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {response.setContentType("text/html;charset=gbk");String path=request.getRequestURI();String actionName=path.substring(path.lastIndexOf("/")+1,path.lastIndexOf("."));Action action=null;if(actionName.equals("login")){action=new LoginAction();}String resultView=action.execute(request, response);request.getRequestDispatcher(resultView).forward(request, response);}?LoginAction
public String execute(HttpServletRequest request,HttpServletResponse response) {String uname=request.getParameter("uname");String upass=request.getParameter("upass");Info u=new Info();u.setUname(uname);u.setUpass(upass);UserBiz userBiz=new UserBizImpl();Info user=userBiz.findUser(u);if(user!=null){return "show.jsp";}else{request.setAttribute("msg", "用户名密码错误！");return "index.jsp";}}?对应的jsp页面代码则是
<body> ${msg } <form name="f1" id="f1" action="login.cc" method="post"> <table border="0"> <tr> <td>Login:</td> <td><input type="text" name="uname" id="login"></td> </tr> <tr> <td>Password:</td> <td><input type="password" name="upass" id="password"></td> </tr> <tr> <td colspan="2" align="center"><input type="submit" value="login user"></td> </tr> </table> </form> </body>?
