What features of Spring ensure accelerated application development?

Spring accelerates application development through the following features:

• Inversion of Control (IoC) and Dependency Injection (DI): simplify dependency management between components, reducing coupling and easing testing.
• Automatic configuration: especially in Spring Boot, allows quick setup without bulky XML configs.
• Modularity and extensive ecosystem: many ready modules for databases, web, security, integration, etc.
• Aspect-Oriented Programming (AOP): separates cross-cutting concerns like logging and transactions from business logic.
• Embedded application server (e.g., in Spring Boot): enables running the app as a standalone service without an external container.

Example of using Spring Boot for quick startup:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

This minimal code launches a web application with auto-configuration.
