下面一段代码给大家分享JavaWeb实现压缩多个文件并下载功能，具体代码如下所示：

//文件名称 String[] names={"one.jpg","two.jpg","three.jpg","four.jpg"}; //四个文件流 FileInputStream input1 = new FileInputStream(new File("文件路径")); FileInputStream input2 = new FileInputStream(new File("文件路径")); FileInputStream input3 = new FileInputStream(new File("文件路径")); FileInputStream input4 = new FileInputStream(new File("文件路径")); FileInputStream[] inputs={input1,input2,input3,input4}; //ZIP打包图片 File zipFile = new File("压缩文件存放路径"); byte[] buf = new byte[1024]; int len; ZipOutputStream zout=new ZipOutputStream(new FileOutputStream(zipFile)); for (int i = 0; i < inputs.length; i++) { FileInputStream in =inputs[i]; zout.putNextEntry(new ZipEntry(names[i])); while ((len = in.read(buf)) > 0) { zout.write(buf, 0, len); } zout.closeEntry(); in.close(); } zout.close(); //下载图片 FileInputStream zipInput =new FileInputStream(zipFile); OutputStream out = response.getOutputStream(); response.setContentType("application/octet-stream"); response.setHeader("Content-Disposition", "attachment; filename=images.zip"); while ((len=zipInput.read(buf))!= -1){ out.write(buf,0,len); } zipInput.close(); out.flush(); out.close(); //删除压缩包 zipFile.delete();
