Spring Boot 3: Trouble with Caching Annotations optimization guide as Expected with Redis
I keep running into I'm building a feature where I'm working with an scenario with caching in my Spring Boot 3 application where I have implemented Redis caching using `@Cacheable` annotations. Despite the cache being configured correctly, I keep hitting the database on subsequent calls instead of retrieving the data from Redis, leading to performance optimization. I have verified that the Redis server is running and reachable. Here's a simplified version of my setup: ```java import org.springframework.cache.annotation.Cacheable; import org.springframework.stereotype.Service; @Service public class UserService { @Cacheable(value = "users", key = "#id") public User getUserById(Long id) { // Simulating a time-consuming database call return userRepository.findById(id).orElse(null); } } ``` I've also added the necessary configuration in my `application.properties`: ```properties spring.cache.type=redis spring.redis.host=localhost spring.redis.port=6379 ``` I am using Spring Boot 3.1.0 and have the following dependencies in my `pom.xml`: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-cache</artifactId> </dependency> ``` I have confirmed that the caching is enabled by adding `@EnableCaching` in my main application class. Despite all of this, the cache seems to not be utilized. When I call `getUserById` several times, I see multiple database hits in the logs, indicating that the caching mechanism is not functioning as expected. If anyone has encountered a similar scenario or can point out what I might be missing, I would greatly appreciate it. Thanks! What's the best practice here? My team is using Java for this mobile app. What am I doing wrong?
