Introduction

Spring has been the go-to framework for building robust Java applications for years. But with increasing demand for rapid development, cloud-native applications, and microservices, a new hero emerged — Spring Boot.

So the question is:

Why would a developer choose Spring Boot over the traditional Spring Framework?

Let’s dive into the reasons and see what makes Spring Boot so popular and practical.

🔄 Quick Overview

✅ 1. Zero to Production — Faster!

With Spring Boot, you can create production-ready apps quickly.

💡 In Spring Framework:

• You manually configure the dispatcher servlet, view resolvers, security filters, data source, etc.

✅ In Spring Boot:

• You get auto-configuration, which means no XML and no unnecessary bean definitions.
• You write your logic — Spring Boot takes care of the rest.

⏱️ Time Saved: Hours (or even days!) during project setup.

✅ 2. Embedded Servers (Tomcat, Jetty, Undertow)

Spring Boot includes an embedded web server. So, there will be no more deployment of WAR files to external servers.

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

➡️ Just run the app — and your server is up on http://localhost:8080.

✅ Benefits:

• No need for an external Tomcat setup
• Easier CI/CD pipeline integration
• Ideal for Docker and cloud deployments
