我的主要要求是：编码的字符串应尽可能短，并且仅包含拉丁字符或base64字母中的字符（不包括我的电话）。 没有其他要求。
使用Google Gson转换
Map为JSON。使用
GZIPOutputStream压缩JSON字符串。使用Apache
Commons
Codec
base64或
base64OutputStream将压缩字节编码为base64字符串。
开球示例：
public static void main(String[] args) throws IOException { Map<String, String> map = new HashMap<String, String>(); map.put("key1", "value1"); map.put("key2", "value2"); map.put("key3", "value3"); String serialized = serialize(map); Map<String, String> deserialized = deserialize(serialized, new TypeToken<Map<String, String>>() {}.getType()); System.out.println(deserialized);}public static String serialize(Object object) throws IOException { ByteArrayOutputStream byteaOut = new ByteArrayOutputStream(); GZIPOutputStream gzipOut = null; try { gzipOut = new GZIPOutputStream(new base64OutputStream(byteaOut)); gzipOut.write(new Gson().toJson(object).getBytes("UTF-8")); } finally { if (gzipOut != null) try { gzipOut.close(); } catch (IOException logOrIgnore) {} } return new String(byteaOut.toByteArray());}public static <T> T deserialize(String string, Type type) throws IOException { ByteArrayOutputStream byteaOut = new ByteArrayOutputStream(); GZIPInputStream gzipIn = null; try { gzipIn = new GZIPInputStream(new base64InputStream(new ByteArrayInputStream(string.getBytes("UTF-8")))); for (int data; (data = gzipIn.read()) > -1;) { byteaOut.write(data); } } finally { if (gzipIn != null) try { gzipIn.close(); } catch (IOException logOrIgnore) {} } return new Gson().fromJson(new String(byteaOut.toByteArray()), type);}
