response sendRedirect 带中文乱码，解决方法

response 使用sendRedirect 带中文跳转:

String path = request.getContextPath();
                String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
                try {
                    response.sendRedirect(basePath+"system/error_forward1?forward_url='produce/mrp?list'&error_info="
                        +URLEncoder.encode("已审核不能修改","utf-8"));
                } catch (IOException e) {
                    e.printStackTrace();
                }

system/error_forward1路径处理:

        String error_info = request.getParameter("error_info");
        String forward_url = request.getParameter("forward_url");

        model.addAttribute("error_info", new String(error_info.getBytes("ISO8859_1"),"utf-8"));
        model.addAttribute("forward_url", forward_url);
