spring-boot jpa caching hibernate jcache Java

After trying multiple solutions online, I still can't figure this out. I need some guidance on I'm sure I'm missing something obvious here, but I'm encountering a frustrating issue with a caching mechanism in my Spring Boot application that uses JCache along with Hibernate for ORM. I have implemented a caching strategy for my entities to improve performance, but I've noticed that the entity state isn't being updated as expected after performing updates. Specifically, after modifying an entity, the cache doesn't seem to reflect the changes until the application is restarted. Here's the relevant portion of my code: ```java @Entity @Cacheable public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; // getters and setters } ``` And in my service class, I have: ```java @Service public class UserService { @Autowired private UserRepository userRepository; @Cacheable(key = "#id") public User getUser(Long id) { return userRepository.findById(id).orElse(null); } @Transactional public User updateUser(Long id, String newName) { User user = userRepository.findById(id).orElseThrow(() -> new EntityNotFoundException("User not found")); user.setName(newName); return userRepository.save(user); } } ``` Despite having the `@Cacheable` annotation on the `getUser` method, when I update a user's name through `updateUser`, the cache still returns the old name when I immediately call `getUser` again. I tried adding a `@CacheEvict` annotation to the `updateUser` method, but it didn't seem to work as expected either: ```java @CacheEvict(key = "#id") public User updateUser(Long id, String newName) { // update logic } ``` I also checked my application properties to ensure that caching is enabled: ```properties spring.cache.jcache.config=classpath:ehcache.xml ``` I verified that my `ehcache.xml` configuration is correctly set up as well. After updating an entity, I expect subsequent reads to pull the updated data from the database, but it seems like the cache is retaining stale data. Is there something I'm missing in terms of cache configuration or annotations? Any insights would be greatly appreciated! This is part of a larger service I'm building. I recently upgraded to Java latest. Any feedback is welcome!
