                    <p>乱码主要是因为<span style="font-family:Arial; font-size:14px">httpServletResponse的</span><span style="font-size:14px; color:rgb(69,69,69); font-family:Helvetica,Tahoma,Arial,sans-serif">header编码问题，</span></p> 

但是，不同浏览器编码又不同，

经过测试，使用一下方法解决：

设置Response头信息编码

        if ("IE".equals(getBrowser(request))) {
            fileName = new String(java.net.URLEncoder.encode(fileName, "UTF-8"));
            response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
        }else{
            fileName = new String(fileName.getBytes("UTF-8"), "iso-8859-1");
            response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
        }

    /**
     * 判断客户端浏览器类型
     * @param request
     * @return
     */
    private String getBrowser(HttpServletRequest request) {
        String UserAgent = request.getHeader("User-Agent").toLowerCase();
        if (UserAgent.indexOf("firefox") >= 0){
            return "FF";
        }else if(UserAgent.indexOf("safari") >= 0 ){
            return "Chrome";
        }else{
            return "IE";
        }
    }

经过以上设置，并验证了谷歌、火狐、搜狗、360、IE这几个浏览器，导出excel的文件名均无乱码
