java代码实现文件打包
网上找了一个文件打包的程序。感觉不错拿来用用^_^
package test; import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; public class Zip { /** * 压缩文件夹 * @param zipPath 生成的zip文件路径 * @param filePath 需要压缩的文件夹路径 * @throws Exception */ public void zipFolder(String zipPath, String filePath) throws Exception { ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipPath)); File f = new File(filePath); zipFiles(out, f, ""); out.close(); } /** * 压缩单一个文件 * @param zipPath 生成的zip文件路径 * @param filePath 需要压缩的文件路径 * @throws Exception */ public void zipFile(String zipPath, String filePath) throws Exception { File f = new File(filePath); FileInputStream fis = new FileInputStream(f); BufferedInputStream bis = new BufferedInputStream(fis); byte[] buf = new byte[1024]; int len; FileOutputStream fos = new FileOutputStream(zipPath); BufferedOutputStream bos = new BufferedOutputStream(fos); ZipOutputStream zos = new ZipOutputStream(bos);//压缩包 ZipEntry ze = new ZipEntry(f.getName());//这是压缩包名里的文件名 zos.putNextEntry(ze);// 写入新的ZIP文件条目并将流定位到条目数据的开始处 while ((len = bis.read(buf)) != -1) { zos.write(buf, 0, len); zos.flush(); } bis.close(); zos.close(); } /** * 递归调用，压缩文件夹和子文件夹的所有文件 * @param out * @param f * @param base * @throws Exception */ private void zipFiles(ZipOutputStream out, File f, String base) throws Exception { if (f.isDirectory()) { File[] fl = f.listFiles(); out.putNextEntry(new ZipEntry(base + "/")); base = base.length() == 0 ? "" : base + "/"; for (int i = 0; i < fl.length; i++) { zipFiles(out, fl[i], base + fl[i].getName());//递归压缩子文件夹 } } else { out.putNextEntry(new ZipEntry(base)); FileInputStream in = new FileInputStream(f); int b; //System.out.println(base); while ((b = in.read()) != -1) { out.write(b); } in.close(); } } /** * @param args */ public static void main(String[] args) { System.out.println("Zip File Begin"); Zip zip = new Zip(); String zipPath = "D:\\test.zip"; String filePath = "D:\\test.txt"; try { zip.zipFile(zipPath, filePath);//压缩文件 //zip.zipFolder(zipPath, filePath);//压缩文件夹 } catch (Exception ex) { ex.printStackTrace(); } System.out.println("Zip File Done"); } }
