使用java zip 压缩文件目录

    @Test
        public void testPackageContent() {
            try {
                FileOutputStream f =
                    new FileOutputStream(BASE_PATH + "/../" + packageName + ".zip");
                CheckedOutputStream csum =
                    new CheckedOutputStream(f, new Adler32());//Adler32 is faster than CRC32
                ZipOutputStream out =
                    new ZipOutputStream(new BufferedOutputStream(csum));
                out.setComment("some comments");
                File srcDir = new File(BASE_PATH);
                zipFile(out, srcDir, "packageName");
                out.close();

            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        /**
         * zip the given file
         * @param out - ZipOutputStream
         * @param srcDir - if it is a file then add this file into zip, if it is dir, then call zipFile cascade
         * @param filePath - the filepath in zipfile
         * @throws IOException
         */
        private void zipFile(ZipOutputStream out, File srcDir, String filePath) throws IOException{
            for(File file : srcDir.listFiles()){
                if(file.isDirectory()){
                    zipFile(out, file, filePath+"/"+file.getName());
                    continue;
                }
                Logger.global.info("Writing file : "+file.getName());
                FileInputStream in = new FileInputStream(file);
                out.putNextEntry(new ZipEntry(filePath+"/"+file.getName()));
                byte[] b = new byte[1024];
                int off = 0;
                while((in.read(b,off,1024)) != -1){
                    out.write(b);
                }
                in.close();
            }
        }
