Мнение 1: Spring is a powerful framework used to create simple and complex Java applications. Its core features include dependency injection, aspect-oriented programming, data access, transaction management, and flexible MVC frameworks. With Spring at its core, an application can support multiple data sources, be integrated with other web technologies, and built with different integration tools. Thanks to its dynamic nature and scalability, developers have the flexibility to quickly build fully functional applications with significantly fewer lines of code than other approaches. Furthermore, the Spring team has made sure that it's kept up-to-date with the latest Java versions so that existing applications can be updated or migrated easily. With all these great benefits for developers, no wonder why Spring has become one of the most popular Java frameworks!
