JSP
1. GET 방식 <a href="boardContent.do?idx=${vo.idx}"> </a>
Java pojo
@GetMapping("/boardContent.do")
public String boardContent(@RequestParam("idx") int idx, Model model) { //?idx=6
Board vo = mapper.boardContent(idx);
model.addAttribute("vo", vo);
return "boardContent";
2. Get 방식 <a href="boardDelete.do/${vo.idx}" class="btn btn-warning btn-sm">삭제</a>
@GetMapping("/boardDelete.do/{idx}") //get 방식2
public String boardDelete(@PathVariable("idx") int idx) //?idx=6
{
mapper.boardDelete(idx);
return "redirect:/boardList.do";
}
버튼 방식은 폼이 <form></form> 있을때는 onclick으로 하고
없을 때는 그냥 a태그에소 href로 걸면된다. 20강
