Spring Boot FAQ: Top Questions

Spring Boot is a Java-based framework used to create stand-alone, production-grade Spring applications with minimal configuration. It simplifies development by embedding servers, eliminating boilerplate code, and providing ready-to-use configurations.

🗺️ Step-by-Step Instructions:

1. Use spring-boot-starter dependencies to bring in required libraries.
2. Create a class with a main() method annotated with @SpringBootApplication.
3. Run your application as a Java application. No external server is required.

📥 Example Input:

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

🏆 Expected Output:

Embedded Tomcat server starts and your application runs on localhost.

📘 Detailed Explanation:

• Auto-Configuration: Spring Boot configures application based on classpath settings.
• Embedded Servers: Includes Tomcat, Jetty, or Undertow by default.
• Production-Ready: Actuator support for monitoring and metrics.

🛠️ Use Cases:

• Creating REST APIs quickly.
• Building microservices architecture.
• Developing CLI or background Java apps.
