乱码主要是因为httpServletResponse的header编码问题,

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
