Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! 이 PR은 Actuator 포트 분리 후 발생한 Spring Security의 요청 차단 문제를 해결하기 위한 것입니다. 별도의 보안 설정을 추가하여 Actuator 엔드포인트에 대한 접근 권한을 관리하고, 메인 보안 설정보다 우선순위를 높여 정상적인 모니터링이 가능하도록 개선했습니다.

Code Review
This pull request introduces ManagementSecurityConfig to configure security for Spring Boot Actuator endpoints, permitting all requests and disabling CSRF. The reviewer recommended configuring the session management policy to STATELESS for these endpoints to prevent unnecessary HTTP session creation and save server memory resources during frequent monitoring requests.

[P2] Actuator SecurityFilterChain에 Stateless 세션 정책 설정 추가 권장
문제점:
현재 managementSecurityFilterChain에는 세션 정책이 설정되어 있지 않습니다. Spring Security의 기본 세션 생성 정책은 IF_REQUIRED이므로, Actuator 엔드포인트 호출 시 불필요한 HTTP 세션이 생성될 수 있습니다.
이유:
특히 Prometheus 메트릭 수집(/actuator/prometheus)이나 주기적인 헬스 체크(/actuator/health)는 모니터링 시스템에 의해 매우 빈번하게 호출됩니다. 세션 정책을 STATELESS로 설정하지 않으면 매 요청마다 세션이 생성 및 유지되어 서버 메모리 리소스를 낭비할 수 있습니다.
개선안:
sessionManagement 설정을 추가하여 세션 정책을 STATELESS로 명시적으로 지정하는 것을 권장합니다.
import org.springframework.security.config.annotation.web.configurers.AbstractHttpConfigurer;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class ManagementSecurityConfig {
@Bean
@Order(0)
public SecurityFilterChain managementSecurityFilterChain(HttpSecurity http) throws Exception {
http
.securityMatcher(EndpointRequest.toAnyEndpoint())
.authorizeHttpRequests(auth -> auth.anyRequest().permitAll())
.sessionManagement(session -> session.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
.csrf(AbstractHttpConfigurer::disable);
return http.build();References
