Walkthrough

The changes enable Spring caching for several service methods by uncommenting previously commented-out @Cacheable annotations. This activates caching for methods in the cafeteria and campus service classes, specifying cache names, keys, and the cache manager. No other logic or method signatures are modified.

Changes

File(s) Change Summary
src/main/java/com/example/Jinus/service/cafeteria/CacheService.java Enabled caching for getCafeteriaList(int campusId) by uncommenting the @Cacheable annotation.
src/main/java/com/example/Jinus/service/cafeteria/CafeteriaQueryService.java Enabled caching for getCafeteriaId(String, int) and getImgUrl(int) by uncommenting @Cacheable.
src/main/java/com/example/Jinus/service/cafeteria/CampusService.java Enabled caching for getUserCampusName(int campusId) and getCampusId(String campusName).

Caches awake from their slumber deep,
Now cafeteria data is theirs to keep!
With annotations freed,
And queries at speed,
The rabbits rejoice—less data to reap!

Tip

⚡️ Faster reviews with caching
  • CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

27-41: Consider using @Cacheable for getDietList method

The getDietList method is using a manual Redis caching implementation with custom TTL calculation based on midnight expiration. Consider whether this could be replaced with a Spring @Cacheable annotation with a custom key generator and TTL configuration to maintain consistency with other caching implementations.

src/main/java/com/example/Jinus/service/cafeteria/CampusService.java (1)

28-30: Consider adding cache for getCampusList method

The getCampusList method returns a list of campuses, but unlike other methods, it doesn't have a @Cacheable annotation. Since campus data is likely to change infrequently, consider adding caching to this method as well for consistency and performance.

15-19: Caching activated for getCafeteriaId method

The @Cacheable annotation is now enabled for the getCafeteriaId method with appropriate configuration:

  • Uses "cafeteriaId" as the cache name
  • Creates a composite key from cafeteria name and campus ID
  • Prevents caching when the result is -1 (not found case)

This is a good practice for query methods that are frequently called with the same parameters.


24-27: Caching activated for getImgUrl method

The @Cacheable annotation is now enabled for the getImgUrl method with appropriate configuration:

  • Uses "cafeteriaUrl" as the cache name
  • Uses cafeteria ID as the cache key
  • Utilizes the same cache manager as other methods

This will improve performance for frequently accessed image URLs.

src/main/java/com/example/Jinus/service/cafeteria/CacheService.java (1)

58-61: Caching activated for getCafeteriaList method

The @Cacheable annotation is now enabled for the getCafeteriaList method:

  • Uses "cafeteriaList" as the cache name
  • Uses campus ID as the cache key
  • Uses the same "contentCacheManager" as other services

This is consistent with the caching approach used in other services and should improve performance for cafeteria list retrieval.

src/main/java/com/example/Jinus/service/cafeteria/CampusService.java (2)

18-21: Caching activated for getUserCampusName method

The @Cacheable annotation is now enabled for the getUserCampusName method:

  • Uses "campusId" as the cache name
  • Uses campus ID as the cache key
  • Uses the standard "contentCacheManager"

This will improve performance for frequently accessed campus name lookups.


32-35: Caching activated for getCampusId method

The @Cacheable annotation is now enabled for the getCampusId method:

  • Uses "campusName" as the cache name
  • Uses campus name as the cache key
  • Uses the standard "contentCacheManager"

This will improve performance for campus ID lookups and is consistent with other caching implementations.
