从流中反序列化json获取空对象

import json

def deserialize_json_from_stream(stream):
    json_data = stream.read()
    obj = json.loads(json_data)
    empty_obj = {}
    empty_obj.update(obj)
    return empty_obj

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonDeserializer {
    public static Object deserializeJsonFromStream(InputStream stream) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        Object obj = objectMapper.readValue(stream, Object.class);
        Object emptyObj = new Object();
        // Copy properties from obj to emptyObj
        // ...
        return emptyObj;
    }
}
