What is Spring Boot and how is it different from the Spring Framework? स्प्रिंग बूट क्या है और यह स्प्रिंग फ्रेमवर्क से कैसे अलग है?

Spring Boot is an opinionated extension of the Spring Framework that removes boilerplate configuration through auto-configuration, starter dependencies, and an embedded server, so you can build stand-alone, production-ready applications with minimal setup.

Spring Framework requires manual configuration of beans, dispatcher servlets, and XML or Java config. Spring Boot auto-configures sensible defaults based on the classpath, letting you override only what you need. It also bundles an embedded servlet container (Tomcat, Jetty, or Undertow), so apps run as a single executable JAR without deploying to an external server.

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