You should use JsonNode object.

for your example you should do this:

 @Controller
 public class Controller{

 @RequestMapping(value = "service/getData", method = RequestMethod.POST)
 @ResponseBody
 public ResponseEntity getData(@RequestBody JsonNode jsonNode){

   ObjectMapper obj = new ObjectMapper();

  if(jsonNode.has("name"){
   Option1 result= obj.convertValue(jsonNode,Option1.class)
  return ResponseEntity(result.name,HttpStatus.OK)
    }    

   else {

   Option2 result= obj.convertValue(jsonNode,Option2.class)
   return ResponseEntity(result.id,HttpStatus.OK)
    }

    return ResponseEntity("ok",HttpStatus.OK)
     }

the JsonNode and the ObjectMapper you should import from here:

import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.databind.JsonNode;

this link should help you to understand better on JsonNode and give you more details.

and this link should help you with the convertValue from JsonNode to java object(POJO).
