Java中字符串数据的压缩和解压缩

这是因为

String outStr = obj.toString("UTF-8");

发送

byte[]

ByteArrayOutputStream

ByteArrayInputStream

GZIPInputStream

byte[] compressed = compress(string); //In the main methodpublic static byte[] compress(String str) throws Exception {    ...    ...    return obj.toByteArray();}public static String decompress(byte[] bytes) throws Exception {    ...    GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(bytes));    ...}
