Java通过gzip对字符串进行压缩和解压缩

public static String uncompressString(String str) throws IOException { if (str == null ¦¦ str.length() == 0) { return str; } ByteArrayOutputStream out = new ByteArrayOutputStream(); ByteArrayInputStream in = new ByteArrayInputStream(str .getBytes("ISO-8859-1")); GZIPInputStream gunzip = new GZIPInputStream(in); byte[] buffer = new byte[256]; int n; while ((n = gunzip.read(buffer)) >= 0) { out.write(buffer, 0, n); } // toString()使用平台默认编码,也可以显式的指定如toString("GBK") return out.toString(); } public static void main(String[] args) throws IOException { String a = compressString("China"); System.out.println(a); System.out.println(a.length()); String b = uncompressString(a); System.out.println(b); }
