http://localhost:9090/ 로 접속하면 아래와 같은 Login 화면이 보여지면 정상.

id : user

password 는 Tomcat이 시작하면 아래와 같이 새로운 Password 가 만들어집니다.

복사해서 넣으시면 됩니다.

참고.

application.yml 에 아래의 설정을 추가하면 Password를 1111으로 셋팅할 수 있다고 합니다.

spring:
  security:
    user:
      name: user
      password: 1111                         # Spring Security Default password 변경

로그인 된 모습

그 다음부터는 http://localhost:9090/ 해서 로그인 화면이 보이지 않습니다.

http://localhost:9090/logout 을 하면 끊깁니다.

---

http://localhost:9090/login

http://localhost:9090/logout

은 Spring Security의 기본 기능이라고 합니다.
