이 메시지가 뜨는 이유

Spring Security에서 "Using generated security password" 메시지는 기본적으로 인메모리 인증을 설정했을 때 자동으로 생성되는 임시 비밀번호를 알려주는 것이다.
이 비밀번호는 개발 환경에서만 사용되며, 실제 배포나 운영 환경에서는 반드시 적절한 사용자 인증 시스템을 설정해야 한다.

기본 인메모리 인증 설정: Spring Boot는 보안을 활성화할 때, 기본적으로 인메모리 사용자 저장소(In-Memory User Store)를 사용하여 간단한 인증을 제공함. 이때 UserDetailsService에 기본 사용자가 자동으로 설정되고, 이 사용자에게 임시 비밀번호가 할당됨.
비밀번호 자동 생성: Spring Boot는 spring-security와 관련된 설정이 없을 경우, 임시로 e8f6be59-d856-4bad-bab3-bafdd7b387bb와 같은 랜덤 비밀번호를 생성하여 출력함. 이 비밀번호는 개발 환경에서만 유효하며, 실제 운영 환경에서 사용하는 것은 권장되지 않음.

이 메시지를 끄고 싶다면?

커스텀 사용자 인증 설정: UserDetailsService를 커스터마이징하여 실제 사용자 인증을 구현하거나, application.properties 또는 application.yml에서 Spring Security 설정을 명시적으로 수정해야 함.

예를 들어, 아래와 같이 application.properties 및 applciation.yml에서 기본 보안을 비활성화할 수 있다.

application.properties

spring.security.user.name=admin
spring.security.user.password=your_secure_password
spring.security.user.roles=ADMIN

application.yml

spring:
  security:
    user:
      name: admin
      password: your_secure_password
      roles: ADMIN

Spring Security 설정에서 직접 사용자 정의: SecurityConfig 클래스를 만들어서 사용자 인증을 설정할 수 있음.

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/**").permitAll() // 모든 요청 허용
                .anyRequest().authenticated()
            .and()
            .formLogin()
                .loginPage("/login") // 로그인 페이지 설정
                .permitAll()
            .and()
            .logout()
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
            .withUser("admin").password("{noop}password").roles("ADMIN"); // 사용자 이름, 비밀번호 설정
    }
}

이렇게 설정하면 Spring Boot의 기본 보안 메시지가 출력되지 않고, 원하는 인증 방식을 사용할 수 있다.
