servlet客户端跳转+服务器端跳转

分类： Java

首先是客户端跳转

[java] view plaincopyprint?
package org.lxh.servletdemo;  
import javax.servlet.ServletException;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
import javax.servlet.http.HttpSession;  
public class ClientRedirectDemo extends HttpServlet {  
    public void doGet(HttpServletRequest req,HttpServletResponse resp)throws ServletException,java.io.IOException{  
        req.getSession().setAttribute("name", "牛儿吃草");  
        req.setAttribute("info", "MLDNJAVA");  
        resp.sendRedirect("get_info.jsp");  
    }  
    public void doPost(HttpServletRequest req,HttpServletResponse resp)throws ServletException,java.io.IOException{  
        this.doGet(req, resp);          
    }  
}  

<servlet>
   <servlet-name>client</servlet-name>
   <servlet-class>org.lxh.servletdemo.ClientRedirectDemo</servlet-class>
</servlet>
<servlet-mapping>
   <servlet-name>client</servlet-name>
   <url-pattern>/ClientRedirectDemo</url-pattern>
</servlet-mapping>

[java] view plaincopyprint?
<%@ page language="java" contentType="text/html" pageEncoding="utf8"%>  
  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
<html>  
  <head>    
    <title>My JSP 'use_javabean_demo01.jsp' starting page</title>  
    <meta http-equiv="pragma" content="no-cache">  
    <meta http-equiv="cache-control" content="no-cache">  
    <meta http-equiv="expires" content="0">      
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">  
    <meta http-equiv="description" content="This is my page">  
  </head>  
   
  <body>  
<%  
    request.setCharacterEncoding("utf-8");  
%>  
<h2>session属性：<%=session.getAttribute("name")%></h2>  
<h2><%=request.getAttribute("info")%></h2>  
  </body>  
</html>  

下面是服务器端跳转

[java] view plaincopyprint?
package org.lxh.servletdemo;  
import javax.servlet.RequestDispatcher;  
import javax.servlet.ServletException;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
import javax.servlet.http.HttpSession;  
public class ServerRedirectDemo extends HttpServlet {  
    public void doGet(HttpServletRequest req,HttpServletResponse resp)throws ServletException,java.io.IOException{  
        req.getSession().setAttribute("name", "牛儿吃草");  
        req.setAttribute("info", "MLDNJAVA");  
        RequestDispatcher rd = req.getRequestDispatcher("get_info.jsp");  
        rd.forward(req, resp);  
    }  
    public void doPost(HttpServletRequest req,HttpServletResponse resp)throws ServletException,java.io.IOException{  
        this.doGet(req, resp);          
    }  
}  

<servlet>
   <servlet-name>server</servlet-name>
   <servlet-class>org.lxh.servletdemo.ServerRedirectDemo</servlet-class>
</servlet>
<servlet-mapping>
   <servlet-name>server</servlet-name>
   <url-pattern>/ServerRedirectDemo</url-pattern>
</servlet-mapping>
