Example :


@Controller
@RequestMapping ("home")

public class HomeController {

       @RequuestMapping (value="/response.do",method=RequestMethod.GET)
       public @ResponseBody String responseHandle (){
             String returnString = "한글 땡땡땡 or UTF-8 Code ";
             return returnString;
       }
     
}



or  ResponseEntity Use

   HttpHeaders responseHeaders = new HttpHeaders();
   responseHeaders.setContentType(MediaType.APPLICATION_JSON);

   String returnString = "한글 땡땡땡 or UTF-8 Code ";
   return new   ResponseEntity<Domain>
          (returnString,responseHeaders,HttpStatus.CREATED);
