Questions & Answers

Q: What is the role of frameworks like Spring in building enterprise applications?

Frameworks like Spring provide basic functionalities and structures, allowing developers to focus on business logic rather than repetitive tasks like security and configuration.

Q: What are some key features of the Spring Framework?

Spring offers features like inversion of control, dependency injection, aspect-oriented programming, and easy integration with databases and other libraries.

Q: How does dependency injection work in Spring?

Dependency injection allows for the injection of dependencies between classes without manually creating and managing instances. Spring handles the instantiation and injection of dependencies, reducing development time and improving modularity.

Q: Can Spring be used with different types of databases?

Yes, Spring provides Spring Data modules that allow for easy integration with various databases, including MySQL, Oracle, and NoSQL databases.

Q: What is aspect-oriented programming in the context of Spring?

Aspect-oriented programming allows for the separation of cross-cutting concerns, such as logging and security, from the core business logic. Spring's aspect-oriented programming capability, known as Spring AOP, helps in managing these concerns effectively.
