java将多个文件进行压缩打包处理

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
