✍️ Sample Spring Framework Questions & Answers
1. Which interface should a Spring bean implement to perform cleanup when the application context is closed?
DisposableBean provides a destroy() method that Spring calls when the container closes, allowing resource cleanup.
2. In Spring, what is a BeanPostProcessor used for?
BeanPostProcessor hooks let you inspect or modify a bean instance right after construction and before or after the initialization callback fires.
3. A Spring application uses RabbitMQ via Spring AMQP. Messages are occasionally lost when the broker restarts. What configuration prevents message loss?
Durable queues survive broker restarts, and persistent messages (deliveryMode=2) are written to disk, together ensuring no messages are lost on broker restart.
4. In Spring, what is meant by 'circular dependency'?
A circular dependency occurs when Bean A depends on Bean B and Bean B depends on Bean A, which can cause Spring to throw a BeanCurrentlyInCreationException with constructor injection.
5. A Spring Boot application experiences 'BeanCurrentlyInCreationException' at startup. What is the most common root cause?
Circular dependencies occur when two or more beans depend on each other, preventing the IoC container from instantiating either without the other already existing.
6. What is the professional standard for managing database transactions in a Spring service layer?
@Transactional declaratively demarcates transaction boundaries, keeping business logic clean and consistent.
