• /springmvc/v2/members라는 부분을 중복을 클래스 단위 RequestMapping을 통해 제거할 수 있다.
  • 클래스 레벨
    • @RequestMapping("/springmvc/v2/members")
  • 메서드 레벨
    • @RequestMapping("/new-form") /springmvc/v2/members/new-form
    • @RequestMapping("/save") /springmvc/v2/members/save
    • @RequestMapping /springmvc/v2/members
