Successfully Porting to Springboot 3, Hibernate 6, and EHCache 3: A Beginner's Guide

Transitioning your Java project from older frameworks to the latest versions can be a daunting task, particularly when it involves integrating core technologies like Springboot, Hibernate, and EHCache. This guide focuses on addressing common issues faced during the migration process from Springboot 2 / Hibernate 5 / EHCache 2 to Java 17 / Springboot 3 / Hibernate 6 / EHCache 3.

The Challenges of Migration

When porting your project, you might encounter several challenges. Below are some issues developers frequently run into:

Cache Listener Events: After fetching data from the database, while the cache successfully stores the data, the expected cache listener events do not fire.

Item Expiration: Even with a designated time-to-live (TTL) of one minute, the cached items fail to expire.

Duplicate Initialization: The EHCache's DemoEntity configuration might be initializing multiple times, potentially leading to the above problems.

With these challenges in mind, let’s explore how to correctly configure your project for successful migration.

Steps to Resolve Common Issues

1. Modify the application.yaml Configuration

Correcting the configuration for Hibernate caching in your application.yaml can significantly improve performance and resolve the listener event firing issue. Here’s the updated configuration you should adopt:

Key Changes:

Added the javax.cache.provider for compatibility with EHCache 3.

Specified the cache uri to point to your EHCache configuration file.

Introduced missing_cache_strategy to avoid issues with non-existent caches.

2. Update the ehcache.xml for Entity Caches

In the ehcache.xml, ensure that the cache alias corresponds to the fully qualified name (FQDN) of the entity class. This step is crucial in preventing duplication and ensuring proper instantiation. Here's a sample of how your ehcache.xml cache configuration should look:

3. Review Your Entity Configuration

Finally, double-check your entity configuration. In your DemoEntity.java, confirm that the caching annotations are in place. Ensure that you utilize the correct caching strategy to maintain data integrity. Here’s what it should look like:

Conclusion

After implementing these changes, the issues you were experiencing should be resolved, and your project should run smoothly using Springboot 3, Hibernate 6, and EHCache 3. Transitioning to newer technologies is essential for longevity and performance enhancement, so don’t hesitate to take the plunge into these frameworks.

Now, with everything updated and adjusted, you can confidently enjoy the benefits of the latest technologies in your Java application!
