多个文件打包压缩怎么处理,如何将多个文件压缩打包

直接上代码!!复制导入包之后直接可当工具类使用!!

public class ZipUtil {private static final int BUFFER_SIZE = 2 * 1024;public static void fileListToZip(List<File> srcFiles , OutputStream out) throws IOException {long start = System.currentTimeMillis();ZipOutputStream zos = null ; try { zos = new ZipOutputStream(out); for (File srcFile : srcFiles) { byte[] buf = new byte[BUFFER_SIZE]; // 防止文件重名导致压缩失败 String fileName = srcFile.getName(); String prefix = fileName.substring(fileName.lastIndexOf(".")); String newFileName = fileName.substring(0, fileName.length()-prefix.length()) + "_" + UUIDUtil.getUUID() + prefix; zos.putNextEntry(new ZipEntry(newFileName)); int len; FileInputStream in = new FileInputStream(srcFile); while ((len = in.read(buf)) != -1){ zos.write(buf, 0, len); } zos.closeEntry(); in.close(); } long end = System.currentTimeMillis(); System.out.println("压缩完成，耗时：" + (end - start) +" ms"); } catch (Exception e) {e.printStackTrace();}finally{ if(zos != null){ try { zos.close(); } catch (IOException e) { e.printStackTrace(); } } }}}

注意：传入的文件列表如果有重名的文件会导致压缩失败，所以要对文件名进行uuid重命名处理
