While not exactly the same, Jackson has Tree Model representation similar to Gson:

JsonNode root = objectMapper.readTree(jsonInput);
return root.get("data").get("data2").get("value").asText();

so you need to traverse it step by step.

EDIT (August 2015)

There actually is now (since Jackson 2.3) support for JSON Pointer expressions with Jackson. So you could alternatively use:

return root.at("/data/data2/value").asText();
