I recommend utilizing Jackson's TreeModel. If you use it and get the String into a JsonNode, then you can just use

jsonNode.get("map_")

and you'll have the string you want.

Edited with code example:

String jsonString = "{"map_":{"FirstName":"Deepak","LastName":"Kabra"}}";

ObjectMapper mapper = new ObjectMapper();
JsonNode obj = mapper.readTree(jsonString);
JsonNode desiredString = actualObj.get("map_");
