Sample application that demonstrates the use of Hibernate as a JPA provider with Spring Data JPA.
The following concepts are currently demonstrated:
| Concept | Description | See |
|---|---|---|
| Spring Data JPA repositories | Perform CRUD operations agains a relational database using the Repository pattern | LibraryRepository.java |
Direct EntityManager access |
Accessing the JPA EntityManager directly for fine-grained control over database interactions |
QuizPersistenceTest.java |
| Collection size | Find size of a mapped collection without having to load all elements in the collection | QuizPersistenceTest.java |
Multiple EntityManagers |
Use multiple EntityManagers in a single application |
springContext.xml |
| Manual identifier generation | Generate entity identifiers manually | Invoice.java and InvoiceRepositoryTest.java |
| JTA transactions | Support JTA transactions across multiple data stores using Bitronix | springContext.xml |
@OneToOne with foreign keys |
@OneToOne association between two entity classes using a foreign key column |
Employee.java |
JPA count query on abstract class |
Executing a count query on an abstract class |
WorkdayRepositoryTest.java |
| Custom JPA functionality | Extending Spring Data JpaRepository to provide custom functionality for all repositories |
ExtendedJpaRepository.java |
| AspectJ integration | Intercepting Spring Data repository method calls using AspectJ | RepositoryInterceptionAdvice.java |
| SQL Injection protection | Use type-safe, parameterized queries to prevent SQL Injection attacks | StockRepositoryTest.java |
| Native SQL queries | Use native SQL queries in cases where either JPQL is inadequate or native SQL is simply easier to write | JobRepository.java |
| Spring Data JPA with Scala | Use Spring Data JPA with Scala classes and traits | SubjectRepository.scala |
Single Table inheritance |
Single-table inheritance for storing related objects | Card.java |
| Polymorphism with generics | Demonstrate inheritance-based polymorphism along with generics | CardInstance.java |
