			return "redirect:freeboardlist";
		} 
		FreeBoardDto freeboard = freeBoardService.findFreeBoardByFreeBoardNo(freeBoardNo); 
		if(freeboard == null) { // 조회된 글이 없을때 리스트로 이동  
			return "redirect:freeboardlist";
		} 
		model.addAttribute("freeBoard", freeboard); 
		return "freeboard/freeboarddetail"; 
	}
