jeecg项目将workbook 的Excel流添加到zip压缩包里导出

1、直接献出代码

Map<String,List<ConfidentialInformation>> typeMap = new HashMap<>();
try {
                //设置导出
                response.addHeader("Cache-Control","no-cache");

                response.setContentType("application/octet-stream;charset=UTF-8");
                String ua = request.getHeader("user-agent");
                ua = ua == null ? null : ua.toLowerCase();
                String docFileName = dateMonth.toString()+"月凭证信息情况.zip";
                if(ua != null && (ua.indexOf("firefox") > 0 || ua.indexOf("safari")>0)){
                    try {
                        docFileName = new String(docFileName.getBytes(),"ISO8859-1");
                        response.addHeader("Content-Disposition","attachment;filename=" + docFileName);
                    } catch (Exception e) {
                    }
                }else{
