Walkthrough

The FollowCommandService methods now return values and include Spring Cache eviction annotations. The following method returns the created Member object, and the unfollowing method returns the followingId string, with both methods configured to evict cached memberInfo entries upon execution.

Changes

Cohort / File(s)	Summary
Follow Service Caching & Return Types src/main/java/novaminds/gradproj/domain/member/service/command/FollowCommandService.java	Added @Caching annotations with cache eviction to following() and unfollowing() methods. Updated method signatures: following returns Member (was void), unfollowing returns String (was void). Added return statements and cache eviction keys targeting memberInfo cache for follower and followed member login IDs.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify cache eviction keys correctly reference method parameters and return values
• Confirm return types align with calling code expectations
• Ensure @Caching annotations use correct cache name (memberInfo) and SpEL expressions

Poem

🐰 A follow becomes a gift, a return so true,
Cache evictions sweep old data through and through,
Members flow forward, their info refreshed anew,
Spring caches sing as the service shines through! ✨

Summary of Changes

Hello @MODUGGAGI, 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 팔로우 및 언팔로우 기능이 실행될 때 관련 사용자 정보 캐시를 자동으로 무효화하여 데이터 일관성을 보장하기 위한 리팩토링입니다. 이를 통해 최신 팔로우 상태가 항상 사용자에게 반영되도록 합니다.

Highlights

• 캐시 무효화 추가: 팔로우 및 언팔로우 작업 시 memberInfo 캐시 데이터를 자동으로 삭제하도록 @CacheEvict 어노테이션이 추가되었습니다.
• 메서드 반환 타입 변경: following 메서드는 void에서 Member로, unfollowing 메서드는 void에서 String으로 반환 타입이 변경되어 캐시 키로 사용될 값을 반환합니다.

Code Review

이번 PR은 팔로우 및 언팔로우 기능 실행 시 관련 사용자들의 캐시 데이터를 삭제하도록 리팩토링하는 내용을 담고 있습니다. Spring의 @CacheEvict 애노테이션을 사용하여 팔로우/언팔로우하는 사용자와 대상 사용자의 memberInfo 캐시를 무효화하도록 구현하셨습니다.

전반적인 로직은 올바르지만, 캐시 무효화를 위해 메서드 시그니처를 변경하는 대신 CacheManager를 직접 사용하여 프로그래밍 방식으로 캐시를 관리하는 방안을 제안합니다. 이 방법은 코드의 의도를 더 명확하게 하고 유지보수성을 높일 수 있습니다. 자세한 내용은 각 파일에 남긴 주석을 참고해주세요.
