Java解压缩zip - 多个文件(包括文件夹)
对多个文件和文件夹进行压缩,对复杂的文件目录进行解压。
压缩方法使用的是可变参数,可以压缩1到多个文件..可以写数组的方式或者一个个写到参数列表里面...
ZipFiles(zip,"abc",new File("d:/English"),new File("d:/发放数据.xls"));
测试文件目录结构:
测试的压缩内容:English文件夹和同级的两个excel文件
File[] files = new File[]{new File("d:/English"),new File("d:/发放数据.xls"),new File("d:/中文名称.xls")};
/** * 压缩文件-由于out要在递归调用外,所以封装一个方法用来 * 调用ZipFiles(ZipOutputStream out,String path,File... srcFiles) * @param zip * @param path * @param srcFiles * @throws IOException * @author isea533 */ public static void ZipFiles(File zip,String path,File... srcFiles) throws IOException{ ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zip)); ZipTest.ZipFiles(out,path,srcFiles); out.close(); System.out.println("*****************压缩完毕*******************"); } /** * 压缩文件-File * @param zipFile zip文件 * @param srcFiles 被压缩源文件 * @author isea533 */ public static void ZipFiles(ZipOutputStream out,String path,File... srcFiles){ path = path.replaceAll("\\*", "/"); if(!path.endsWith("/")){ path+="/"; } byte[] buf = new byte[1024]; try { for(int i=0;i<srcFiles.length;i++){ if(srcFiles[i].isDirectory()){ File[] files = srcFiles[i].listFiles(); String srcPath = srcFiles[i].getName(); srcPath = srcPath.replaceAll("\\*", "/"); if(!srcPath.endsWith("/")){ srcPath+="/"; } out.putNextEntry(new ZipEntry(path+srcPath)); ZipFiles(out,path+srcPath,files); } else{ FileInputStream in = new FileInputStream(srcFiles[i]); System.out.println(path + srcFiles[i].getName()); out.putNextEntry(new ZipEntry(path + srcFiles[i].getName())); int len; while((len=in.read(buf))>0){ out.write(buf,0,len); } out.closeEntry(); in.close(); } } } catch (Exception e) { e.printStackTrace(); } }
/** * 解压到指定目录 * @param zipPath * @param descDir * @author isea533 */ public static void unZipFiles(String zipPath,String descDir)throws IOException{ unZipFiles(new File(zipPath), descDir); } /** * 解压文件到指定目录 * @param zipFile * @param descDir * @author isea533 */ @SuppressWarnings("rawtypes") public static void unZipFiles(File zipFile,String descDir)throws IOException{ File pathFile = new File(descDir); if(!pathFile.exists()){ pathFile.mkdirs(); } ZipFile zip = new ZipFile(zipFile); for(Enumeration entries = zip.getEntries();entries.hasMoreElements();){ ZipEntry entry = (ZipEntry)entries.nextElement(); String zipEntryName = entry.getName(); InputStream in = zip.getInputStream(entry); String outPath = (descDir+zipEntryName).replaceAll("\\*", "/");; //判断路径是否存在,不存在则创建文件路径 File file = new File(outPath.substring(0, outPath.lastIndexOf('/'))); if(!file.exists()){ file.mkdirs(); } //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压 if(new File(outPath).isDirectory()){ continue; } //输出文件路径信息 System.out.println(outPath); OutputStream out = new FileOutputStream(outPath); byte[] buf1 = new byte[1024]; int len; while((len=in.read(buf1))>0){ out.write(buf1,0,len); } in.close(); out.close(); } System.out.println("******************解压完毕********************"); }
测试方法:
public static void main(String[] args) throws IOException { /** * 压缩文件 */ File[] files = new File[]{new File("d:/English"),new File("d:/发放数据.xls"),new File("d:/中文名称.xls")}; File zip = new File("d:/压缩.zip"); ZipFiles(zip,"abc",files); /** * 解压文件 */ File zipFile = new File("d:/压缩.zip"); String path = "d:/zipfile/"; unZipFiles(zipFile, path); }
输出结果:
