Spring 공유 캘린더 프로젝트 로그인 알고리즘 참고
https://cordingdoah.tistory.com/112
회원가입 화면과 db에 등록될 수 있도록 처리를 해보려고 한다
기존 로그인에서 했던 것과 비슷하게 하면 되는데 좀 더 자세히 설명을 해보겠다!

위의 컨트롤러에서 회원가입의 관련된 부분은 아래부분
/* 로그인 화면 --> 회원가입 버튼 클릭 */
@RequestMapping(value = "/register", method = RequestMethod.GET)
public String register() {
return "register";
}
/* 회원가입 화면 --> 확인 버튼 */
@ResponseBody
@RequestMapping(value = "/register", method = RequestMethod.POST)
public int register(member m) {
return m_dao.Register(m);
}
첫번째 메소드는 로그인창에서 회원가입 클릭 했을 때 실행
두번째 메소드는 회원가입창에서 확인버튼을 클릭했을 때 실행

대략적으로 설명을하자면 로그인 화면에서 회원가입 버튼을 클릭하면 /register로 가게되는데 컨트롤러에서 인식을 하고 register.jsp 화면을 웹에 띄워주고 회원가입 화면에서 정보를 입력하고 확인을 클릭하면 ajax를 통해 url로 register를 받게되고 다시 컨트롤러로 돌아가 sql문을 실행 조건이 맞으면 가입성공
-->결과 화면
