利用java解压.zip的压缩文件
这段代码是我从网上直接复制下来的，写的真的很不错，可以直接运行public class UnzipFile { /** * 解压zip文件 * * @param targetPath文件解压后的路径 * @param zipFilePath文件的绝对路径 */ public void unzipFile(String targetPath, String zipFilePath) { try { File zipFile = new File(zipFilePath); InputStream is = new FileInputStream(zipFile); ZipInputStream zis = new ZipInputStream(is); ZipEntry entry = null; System.out.println("开始解压:" + zipFile.getName() + "..."); //开始解压 while ((entry = zis.getNextEntry()) != null) { String zipPath = entry.getName(); System.out.println("entry.getName() = "+entry.getName()); try { //判断压缩文件内是目录还是文件 if (entry.isDirectory()) {//如果是目录，创建它 File zipFolder = new File(targetPath + File.separator + zipPath); if (!zipFolder.exists()) { zipFolder.mkdirs(); } } else {//如果是文件则将其读出 File file = new File(targetPath + File.separator + zipPath); if (!file.exists()) { File pathDir = file.getParentFile(); pathDir.mkdirs(); file.createNewFile(); } FileOutputStream fos = new FileOutputStream(file); int bread; while ((bread = zis.read()) != -1) { fos.write(bread); } fos.close(); } System.out.println("成功解压:" + zipPath); } catch (Exception e) { System.out.println("解压" + zipPath + "失败"); continue; } } zis.close(); is.close(); System.out.println("解压结束"); } catch (Exception e) { e.printStackTrace(); } } /** * @param args */ public static void main(String[] args) { String path = System.getProperty("user.dir"); //取得当前项目的根目录 System.out.println(path); String targetPath = path+"\\tmp"; //文件解压后的路径 String zipFile = "D:\\tmp\\田.zip";//文件的绝对路径 UnzipFile unzip = new UnzipFile(); unzip.unzipFile(targetPath, zipFile); } }
