Key Differences from the Spring Framework: Category Spring Spring Boot Configuration Spring Framework requires extensive XML or Java-based configuration Spring Boot uses auto-configuration and convention over configuration Embedded Server Spring Boot comes with embedded servers, so you can run applications directly. Spring Boot comes with embedded servers, so you can run applications directly. Dependencies Spring Framework requires manual dependency management Spring Boot uses “starters” to simplify dependency management Production-Ready Features Spring Framework does not provide these out of the box. Spring Framework applications typically need an external server (e.g., Tomcat, Jetty). Spring Vs Spring Boot Example: Spring Framework: Spring Boot: @SpringBootApplication public class MySpringBootApp { public static void main(String[] args) { SpringApplication.run(MySpringBootApp.class, args); }
