Spring Boot JPA Entity Field Encryption — Securing Sensitive Data with AttributeConverter
What you’ll learn:
• How to encrypt selected entity fields in a Spring Boot JPA application• How to use @Convert and AttributeConverter for field-level encryption• How to centralize AES-based encrypt/decrypt logic with EncryptDecryptUtil• How to protect street, city, and country fields using an Address entity example• How to keep the service layer working with normal String values while storing encrypted data in the database
With this approach, you avoid scattering encryption logic across service methods and instead keep it centralized in the persistence layer. That keeps the codebase cleaner while ensuring sensitive columns are not stored as plain text in the database.
For more details, check the Medium link below — the article walks through the setup and sample implementation step by step.
