# sdjpa4-demo
|
|
|
|
Runnable companion project for [Spring Data JPA 3 to 4 Migration Guide](https://ankurm.com/spring-data-jpa-3-to-4-migration-guide-2/) on ankurm.com.
|
|
|
|
Four entities, two repositories, a `@NullMarked` package, seven passing behavior tests, and an A-G demo runner that prints every labelled console output shown in the article. Boots H2 in memory, so there's nothing to install beyond a JDK.
|
|
|
|
Built and verified on Eclipse Temurin JDK 21.0.11, Spring Boot 4.0.6, Spring Data JPA 4.0.6, Hibernate ORM 7.2, H2 in-memory.
|
