SpringMVC如何用Post方式重定向

      
    @RequestMapping(value = “postPayAmount”, method = RequestMethod.GET)   
    public RedirectView postPayAmount(httpsession session,ModelMap map) {   
        return new RedirectView(WsUrlConf.URI_PAY,true,false,false);//最后的参数为false代表以post方式提交请求   
    }  

    public static void doBgPostReq(HttpServletResponse response,String postUrl,Map<String, ?> paramMap) throws IOException {
        response.setContentType( "text/html;charset=utf-8");   
        PrintWriter out = response.getWriter();  
        out.println("<form name='postSubmit' method='post' action='"+postUrl+"' >");  
        for (String key : paramMap.keySet()) {
            out.println("<input type='hidden' name='"+key+"' value='" + paramMap.get(key)+ "'>");
        }
        out.println("</form>");   
        out.println("<script>");   
        out.println("  document.postSubmit.submit()");   
        out.println("</script>");   
    }

    @RequestMapping(value = "doPostRedirectView.do", method = RequestMethod.GET)
    @ResponseBody
    public void doPostRedirectView(HttpServletRequest request,HttpServletResponse response,ModelMap map) throws IOException {
        logger.debug("-----进入了doPostRedirectView----");
        map.put("aaa", "aaaa");
        HttpUtils.doBgPostReq(response, "doPostReq.do", map);
    }

  <form action="welcome1" method="post">
        <input type="submit" value="post-请求转发">
  </form>

  <br>
  <br>

  <form action="welcome2" method="post">
      <input type="submit" value="post-重定向">
  </form>

@Controller
public class SpringMvcController {

    @RequestMapping(path = "welcome1",method = RequestMethod.POST)
    public String welcome1(){

        return  "success";        //默认使用请求转发
    }

    @RequestMapping(path = "welcome2",method = RequestMethod.POST)
    public String welcome2(){

        return  "redirect:success.html";        //使用重定向
    }

}
