Jackson - 递归解析成 Map<String, Object>
我试图简化我的代码:我想存储键和值(所有字符串)。
我实际上正在使用一个来存储它。hat 方式可以是值 () 或新节点 ()。Map<String, Object>
Object
String
Map<String, Object>
如何简化此代码?递归函数会很好。
try {
JsonParser jsonParser = new JsonFactory().createJsonParser(content);
jsonParser.nextToken();

jsonParser.nextToken();
if (jsonParser.getCurrentToken() == JsonToken.START_OBJECT) {
while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
String key = jsonParser.getCurrentName();
jsonParser.nextToken();
if (jsonParser.getCurrentToken() == JsonToken.START_OBJECT) {
mData.put(key, new HashMap<String, Object>());
