Spring Framework FAQ: Top Questions

Spring provides seamless integration with JPA using Spring Data JPA, which abstracts boilerplate code for repositories and supports powerful query capabilities.

📘 Steps:

1. Define JPA entity and repository interface.
2. Use @EnableJpaRepositories and a DataSource.

📥 Example:

@Entity
public class Product {
  @Id
  private Long id;
  private String name;
}

public interface ProductRepository extends JpaRepository<Product, Long> {
}

🏆 Expected Output:

Spring manages entity persistence, CRUD queries, and transactions automatically.

🛠️ Use Cases:

• Rapid development of data access layers.
• Flexible query support via method names or JPQL.
