java 把多个文件根据url压缩到一个压缩包中并相应浏览器

String time = GetDate.date2Str(new Date(), GetDate.yyyymmddhhmmss);
String zipName = "浦发律师函" + time +".zip"  ; // 下载压缩包的名字
 response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(zipName, "UTF-8")); // 防止中文乱码
 response.setContentType("application/octet-stream;charset=UTF-8");
response.addHeader("Pargam", "no-cache");
response.addHeader("Cache-Control", "no-cache");
ZipOutputStream out = new ZipOutputStream(response.getOutputStream()); // 浏览器下载

// 这里需要根据自己的业务来书写相关的业务代码 我这里为了举例子 直接写死了
