Issues with Spring Boot and Hibernate Caching - Entities Not Being Cached as Expected
I'm refactoring my project and I recently switched to I'm a bit lost with I've hit a wall trying to I'm facing an issue where entities in my Spring Boot application are not being cached as expected when using Hibernate's second-level cache......... I'm using Spring Boot 2.5.4 with Hibernate 5.5.3 and Ehcache as my caching provider. Despite enabling caching, it seems my entities are being fetched from the database every time instead of being retrieved from the cache. I've annotated my entities with `@Cacheable` like this: ```java import javax.persistence.*; import org.hibernate.annotations.Cache; import org.hibernate.annotations.CacheConcurrencyStrategy; @Entity @Table(name = "user") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String username; // getters and setters } ``` I've also added `@EnableCaching` in my main application class and configured Ehcache in my `application.properties` file like this: ```properties spring.jpa.properties.hibernate.cache.use_second_level_cache=true spring.jpa.properties.hibernate.cache.region.factory_class=org.hibernate.cache.jcache.JCacheRegionFactory spring.cache.jcache.config=classpath:ehcache.xml ``` In `ehcache.xml`, I've defined my caching strategy: ```xml <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.ehcache.org/xml/ehcache.xsd"> <defaultCache> <expiry> <ttl unit="seconds">120</ttl> </expiry> <memory store="heap" size="1000"/> </defaultCache> <cache name="user" maxEntriesLocalHeap="1000"> <timeToLiveSeconds>120</timeToLiveSeconds> </cache> </ehcache> ``` However, when I run a query to fetch users, I can see in the logs that Hibernate is hitting the database every time. I've also tried clearing the cache manually using `entityManager.clear()` but it doesn't seem to help. Is there something I'm missing in the configuration, or could there be an issue with how the caching is set up in Hibernate? Any insights or suggestions would be appreciated! Any help would be greatly appreciated! I appreciate any insights! My team is using Java for this REST API. Could someone point me to the right documentation?
