@GetMapping("/modify")

public String modify(@RequestParam("board_info_idx") int board_info_idx,

@RequestParam("content_idx") int content_idx,Model model,

@ModelAttribute("modifyContentBean") ContentBean modifyContentBean) {

model.addAttribute("board_info_idx", board_info_idx);

model.addAttribute("content_idx", content_idx);

// ContentBean tempContentBean = boardService.getContentInfo(content_idx);

// modifyContentBean.setContent_writer_name(tempContentBean.getContent_writer_name());

// modifyContentBean.setContent_date(tempContentBean.getContent_date());

// modifyContentBean.setContent_subject(tempContentBean.getContent_subject());

// modifyContentBean.setContent_text(tempContentBean.getContent_text());

// modifyContentBean.setContent_file(tempContentBean.getContent_file());

// modifyContentBean.setContent_writer_idx(tempContentBean.getContent_writer_idx());

// modifyContentBean.setContent_board_idx(tempContentBean.getContent_board_idx());

// modifyContentBean.setContent_idx(tempContentBean.getContent_idx());

modifyContentBean  = boardService.getContentInfo(content_idx);

return "board/modify";

}

지금 주석처리해놓은 부분이 원래 강의해서 한 내용이고 그 밑에 modifyContentBean  = boardService.getContentInfo(content_idx); 이부분이 제가생각한부분인데 왜 tempContentBean에 넣어서 일일이 modifyContentBean의 setter에 넣어주는거죠? 그냥 바로 modifyContentBean에다가 넣으면 왜안되는건가요?
