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   
    }  

/**
     * @Description: 后台进行POST请求(请写在代码执行结尾)
     * @return void  返回类型
     */
    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>");   
    }
