Ticket 08: Implement Caching for Recipe Retrieval

[markcdev101]

Description: Use Redis to cache recipe retrieval. Store recipes in cache for faster access on subsequent requests.

Spring Boot Concepts:

• Spring Cache: @Cacheable, @CacheEvict annotations
• Redis Integration

Guide:

• Set up Redis in Docker using docker-compose.yml.
• Add Spring Boot cache support (@EnableCaching in your main class).
• Use @Cacheable on the GET /recipes/{id} method in RecipeService.
• Use @CacheEvict on the update and delete methods to invalidate cache.
• Write tests to ensure caching works as expected.

Acceptance Criteria:

• [x] - Recipe retrieval is cached in Redis.
• [x] - Cache invalidates on recipe update or delete.
• [ ] - Unit tests for caching behavior.

for deleting entries in the cache

@CacheEvict(value = "recipes", key = "#id")

For adding entries in the cache

@Cacheable(value = "recipes", key = "#id")

Skipping the last requirement of unit testing the cache, as it needs Redis embedded. Will look for a workaround in the future.,
