- 컨트롤러에서 DI받는 객체의 타입을 변경...
- 서블릿에 등록한 객체를 SCriptPasswordEncoder?로 변경
- 컨트롤러의 패스워드 인코더 타입을 수정
-> ✨✨상위인 PasswordEncoder로 한다!

✨MemberService는 Spring에 없다!!
1) MemberService를 Spring에 등록시키자
-> ✨✨ @Component
2) @AutoWired로 MemberService를 부르자
-> ✨✨ @AutoWired private MemberService memberService
-> memberService로 다루자
