java解压rar

	public static void unrar(String source, String dest) throws IOException {
		IInArchive archive;
		RandomAccessFile randomAccessFile;
		// 第一个参数是需要解压的压缩包路径，第二个参数参考JdkAPI文档的RandomAccessFile
		//r代表以只读的方式打开文本，也就意味着不能用write来操作文件
		randomAccessFile = new RandomAccessFile(source, "r");
		archive = SevenZip.openInArchive(null, // null - autodetect
			new RandomAccessFileInStream(randomAccessFile));
		int[] in = new int[archive.getNumberOfItems()];
		for (int i = 0; i < in.length; i++) {
			in[i] = i;
		}
		archive.extract(in, false, new RarExtractCallback(archive, new File(dest).getAbsolutePath() + "/"));
		archive.close();
		randomAccessFile.close();
