Navigating Hibernate Search with Jakarta Persistence

Hibernate Search is a powerful tool that allows developers using Hibernate ORM to perform full-text search capabilities in their applications. However, transitioning from traditional javax.persistence.EntityManager to jakarta.persistence.EntityManager can sometimes lead to unexpected challenges, particularly with compatibility issues in libraries. In this post, we will address a common problem faced by developers working with Spring Boot and Hibernate Search, and provide a simple solution to ensure everything runs smoothly.

The Problem

Many developers have encountered this situation when using Hibernate Search in a Spring Boot application that relies on jakarta.persistence.EntityManager. The specific issue arises when trying to create a search session using the line of code:

An error message indicates that the Search.session() method requires javax.persistence.EntityManager, which seems incompatible with the jakarta.persistence.EntityManager in use. This confusion is common, particularly after the move towards the new Jakarta EE specifications.

Solution: Switching to the Jakarta ORM Mapper

To resolve this issue, the solution lies in utilizing the Jakarta version of the Hibernate Search ORM mapper. Since you are using Spring Boot 3, which is built upon the jakarta.* namespace, ensure you are using the appropriate dependencies.

Step-by-Step Implementation

Update Your Gradle File: Modify your build.gradle file to include the Jakarta version of the Hibernate Search ORM mapper instead of the traditional version. This is a pivotal change that aligns your project with the Jakarta EE standards.

Clean and Rebuild Your Project: After making changes to your dependencies, it’s always best to clean and rebuild your project to ensure that all new dependencies are correctly downloaded and integrated.

Test Your Implementation: Finally, run your application and execute the search functionality to verify that the issue has been resolved. The line previously causing the error should now work seamlessly, allowing you to fetch search results as intended.

Conclusion

Transitioning from javax.persistence to jakarta.persistence can come with its set of challenges, particularly in compatibility between different libraries. By updating to the Jakarta version of the Hibernate Search ORM mapper, you can continue to leverage Hibernate's powerful search capabilities without running into dependency issues. This approach not only resolves the immediate problem but also sets a solid foundation for future developments in your Spring Boot applications.

Make sure to stay updated with the latest dependency versions and specifications, as the ecosystem continues to evolve. Happy coding!
