微软向兼容性靠拢,使得IE11浏览器标识变成Mozilla,导致处理下载文件时出现乱码问题,但不无解决方法,

查看请求发现IE11的标识 rv:11,这里区分了IE11所以

StringUtils.contains(userAgent, "rv:11")即可解决问题

ResponseUtill.download(request, response, "人员管理基本信息.xls", "multipart/form-data");

/** * 文件下载. * * <br>��param: request * <br>��param: response * <br>��param: name 文件名. * <br>��param: contentType 文件类型. * @author chengyuebin */ public static void download(HttpServletRequest request,

                                    String name,
                                    String contentType) throws Exception {
            // 最终返回给浏览器的文件名.
            String finalFileName = null;
    
            final String userAgent = request.getHeader("USER-AGENT");
            // IE浏览器.
            if(StringUtils.contains(userAgent, "MSIE") || StringUtils.contains(userAgent, "rv:11")) {
                finalFileName = URLEncoder.encode(name,"UTF8");
            }
            // Google,火狐浏览器
            else if(StringUtils.contains(userAgent, "Mozilla")) {
                finalFileName = new String(name.getBytes(), "ISO8859-1");
            }
            // 其他浏览器.
            else{
                finalFileName = URLEncoder.encode(name,"UTF8");
            }
    
            // 告诉浏览器用什么软件可以打开此文件.
            response.setHeader("content-Type", contentType);
            // 下载文件的默认名称.
            response.setHeader("Content-Disposition", "attachment;filename=" + finalFileName);
            // 编码.
            response.setCharacterEncoding("UTF-8");
    
            Resource resource = new ClassPathResource(name);
            IOUtils.copy(resource.getInputStream(), response.getOutputStream());
            response.flushBuffer();
        }
    
    }
