事实证明，使用Gson做到这一点非常容易，尤其是使用2.3中引入的JsonReader.getPath（）方法时。
static void parseJson(String json) throws IOException { JsonReader reader = new JsonReader(new StringReader(json)); reader.setLenient(true); while (true) { JsonToken token = reader.peek(); switch (token) { case BEGIN_ARRAY: reader.beginArray(); break; case END_ARRAY: reader.endArray(); break; case BEGIN_OBJECT: reader.beginObject(); break; case END_OBJECT: reader.endObject(); break; case NAME: reader.nextName(); break; case STRING: String s = reader.nextString(); print(reader.getPath(), quote(s)); break; case NUMBER: String n = reader.nextString(); print(reader.getPath(), n); break; case BOOLEAN: boolean b = reader.nextBoolean(); print(reader.getPath(), b); break; case NULL: reader.nextNull(); break; case END_document: return; } }}static private void print(String path, Object value) { path = path.substring(2); path = PATTERN.matcher(path).replaceAll(""); System.out.println(path + ": " + value);}static private String quote(String s) { return new StringBuilder() .append('"') .append(s) .append('"') .toString();}static final String REGEX = "\[[0-9]+\]";static final Pattern PATTERN = Pattern.compile(REGEX);
