Questions & Answers

Q: How does Spring framework handle dependencies and why is it popular?

Spring framework uses dependency injection to manage dependencies, allowing for loose coupling between classes and easy configuration. This enables easy integration and testing and has contributed to the popularity of Spring.

Q: What is aspect-oriented programming and how does Spring support it?

Aspect-oriented programming is a programming paradigm that enables the separation of cross-cutting concerns from the main business logic. Spring supports AOP through its own Spring AOP framework, as well as integration with other AOP frameworks like AspectJ.

Q: What are some frameworks and technologies that Spring integrates with?

Spring integrates with various frameworks and technologies, including JDBC for database access, Hibernate for object-relational mapping, JPA for Java persistence, and RESTful web services for building web applications.

Q: How does Spring handle caching and what are its benefits?

Spring provides caching support, allowing developers to cache the results of frequently accessed data or computationally expensive methods. This can significantly improve performance and reduce resource consumption.

Q: What are the key features of Spring Batch framework?

Spring Batch offers features like restartability, chunk processing for efficient memory management, easy transaction management, and parallel processing for improved performance in batch processing applications.

Summary & Key Takeaways

  • Spring framework gained popularity due to its dependency injection feature, which allows for easy management of dependencies and flexible configuration through XML or annotations.

  • Aspect-oriented programming is another key feature of Spring, offering flexible and reusable code for cross-cutting concerns such as logging and security.

  • Spring provides integration with various frameworks and technologies, including JDBC, Hibernate, JPA, and RESTful web services.
