The idiomatic way would be to use an exception handler instead of catching the exception in your regular request handling method. The type of exception determines the response code. (403 for security error, 500 for unexpected platform exceptions, whatever you like)

@ResponseStatus(HttpStatus.BAD_REQUEST)
public String handleAppException(MyApplicationException ex) {

}

@ExceptionHandler(Exception.class)
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public String handleAppException(Exception ex) {
  return ex.getMessage();
}
