What are the main tasks solved by the Spring framework in application development?

Spring is a popular framework for developing Java applications that addresses several key tasks:

• Inversion of Control (IoC) and Dependency Injection (DI): simplifies dependency management between components, enhancing modularity and testability.
• Configuration management: allows centralized configuration of applications via annotations or XML.
• Web request handling: with Spring MVC, it is easy to create REST APIs and web applications.
• Transactional management: simplifies working with transactions in databases.
• Integration with other technologies: supports working with databases, security, message queues, and more.

Thus, Spring helps create scalable, maintainable, and easily testable applications.
