一、第一种重定向

• index.jsp

重定向controllr

• web.xml

         
              
       
        springmvc
               
       
        org.springframework.web.servlet.DispatcherServlet
               
                   
        
         contextConfigLocation
                    
        
         classpath:springmvc-servlet.xml
                
           
          
              
       
        springmvc
               
       
        /
           
          
              
       
        index.html
               
       
        index.htm
               
       
        index.jsp
               
       
        default.html
               
       
        default.htm
               
       
        default.jsp
           
      
     

• springmvc-servlet.xml

 

• controller

package com.shyroke.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.support.RedirectAttributes;import org.springframework.web.servlet.mvc.support.RedirectAttributesModelMap;import org.springframework.web.servlet.view.RedirectView;@Controller@RequestMapping(value="/Usercontroller")public class UserController {        @RequestMapping(value="/redired")    public ModelAndView redired(HttpServletRequest request){        ModelAndView modelAndView=new ModelAndView();        modelAndView.addObject("userName", "admin");        modelAndView.addObject("passWord", "123520");        RedirectView redirectView=new RedirectView(request.getContextPath()+"/views/success.jsp");        modelAndView.setView(redirectView);                return modelAndView;            }}

 

• success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%>    <%@ page isELIgnored="false" %>
                     重定向传值el表达式要加param。变量名            userName:${param.userName}            passWord:${param.passWord}    

• <%@ page isELIgnored="false" %> 该工程的jsp版本为1.2 默认不开启el表达式，所以该加上此行否则el表达式不生效。

• 结果

 

 

二、第二种重定向

• 　　除了controller层之外其他配置都与第一种相同

package com.shyroke.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.support.RedirectAttributes;import org.springframework.web.servlet.mvc.support.RedirectAttributesModelMap;import org.springframework.web.servlet.view.RedirectView;@Controller@RequestMapping(value="/Usercontroller")public class UserController {        @RequestMapping(value="/redired")    public String redired(HttpServletRequest request){                        String url="/views/success.jsp?userName=user1&passWord=111";                return "redirect:"+url;            }}

结果：
