          required=false를 사용해서 필수가 아니라는 것을 명시한다.

 

- 파라미터 값이 없을 경우 기본값을 지정할수 있다.

        @RequestParam(value="pageNum",defaultValue="1") int pageNum){

- view 정보를 

    ModelAndView mv = new ModelAndView("boardList"); 파라미터로 넘기면 따로 지정하지 않아도 된다.

(   boardList.jsp페이지로..)

 

- 페이지 처리에서 검색조건을 받을 경우 넘길때  받은 조건내용를 보내야 한다. 다음 페이지에서도 검색조건으로 보여야 하기 때문에 .

(14) BoardDetailController.java

- ModelAndView를 생성 해서 addObject로 넘기지 않고

  public String detail(@RequestParam("num") int num, Model model){
     파라미터에 Model 추가해서 사용해도 된다.

 넘길때는 addAttribute

 

- 파라미터에 받을 객체를 사용하면 받을 수 있다. HttpSession, ...
