Yes, you can bind JSON to a POJO or HashMap, both using ObjectMapper.readValue() method, like:

   ObjectMapper mapper = new ObjectMapper();

   Map<String,Object> map = mapper.readValue(jsonInput, Map.class);

   MyBean bean = mapper.readValue(jsonInput, MyBean.class); // assuming it has proper public fields or setters
