对于三大框架的反思

本文主要是介绍对于三大框架的反思，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

  现在许许多多的初学者和程序员，都在趋之若鹜地学习Web开发的宝典级框架：Struts2，Spring，Hibernate。似乎这些框架成为了一个人是否精通Java，是否会写J2EE程序的唯一事实标准和找工作的必备基础。

 
public class LoginServlet extends HttpServlet {    
    
    /* (non-Javadoc)   
     * @see javax.servlet.http.HttpServlet#doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)   
     */    
    @Override    
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {    
        String message = null;    
        RequestDispatcher dispatcher = req.getRequestDispatcher("/result.jsp");    
        String name = req.getParameter("name");    
        String password = req.getParameter("password");    
            
        UserHandler userHandler = new UserHandler();    
        if(userHandler.authenticate(name, password)) {    
            message = "恭喜你，登录成功";    
        } else {    
            message = "对不起，登录失败";    
        }    
            
        req.setAttribute("message", message);    
        dispatcher.forward(req, resp);    
    }    
}    

 
<servlet>    
  <servlet-name>Login</servlet-name>    
    <servlet-class>    
      com.demo2do.servlet.LoginServlet    
  </servlet-class>    
</servlet>    
<servlet-mapping>    
  <servlet-name>Login</servlet-name>    
  <url-pattern>    
    /Login    
  </url-pattern>    
</servlet-mapping>    

 
<%    
     String name = request.getParameter("name");    
     String password = request.getParameter("password");    
    
     UserHandler userHandler = new UserHandler();    
     if(userHandler.authenticate(name, password)) {    
%>    
<p>恭喜你，登录成功</p>    
<%    
      } else {    
%>    
<p>对不起，登录失败</p>    
<%    
      }    
%>
