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();
