Query params in Request in spring mvc

Question

How can I query in Request Param in Spring MVC like http://localhost:8075/healthcheck?format=short OR http://localhost:8075/healthcheck?format=full

@RestController
public class HealthController implements ErrorController{

@GetMapping(value = "/healthcheck", produces = "application/json")
 public HashMap<String, String> shorts(@RequestParam("format") String format1){
     HashMap<String, String> maps
             = new HashMap<String, String>();
     if(format1.equals("short") ){
         System.out.println("--short111--"+format1);
         maps.put("status", "OK");
        //return map;
     } else if (format1.equals("full")) {
         System.out.println("--Full111--"+format1);
         SimpleDateFormat formatter = new SimpleDateFormat(
                 "yyyy-MM-dd 'T' HH:mm:ssZ");
         Date date = new Date(System.currentTimeMillis());
         String formattedString = formatter.format(date);
         maps.put("currentTime", formattedString);
         maps.put("status", "OK");
     }
     return maps;
 }

@GetMapping(value = "/healthcheck", produces = "application/json")
 public HashMap<String, String> full(@RequestParam(defaultValue="full") String format){
     System.out.println("full");
     HashMap<String, String> map
             = new HashMap<String, String>();
     SimpleDateFormat formatter = new SimpleDateFormat(
             "yyyy-MM-dd 'T' HH:mm:ssZ");
     Date date = new Date(System.currentTimeMillis());
     String formattedString = formatter.format(date);
     map.put("currentTime", formattedString);
     map.put("status", "OK");
     return map;
 }

compare the param value format for short or full
