Spring Boot FAQ: Top Questions

The @SpringBootApplication annotation is a convenience annotation that combines @Configuration, @EnableAutoConfiguration, and @ComponentScan.

📘 Detailed Explanation:

• @Configuration: Marks the class as a source of bean definitions.
• @EnableAutoConfiguration: Automatically configures Spring application based on the classpath.
• @ComponentScan: Enables scanning of components, configurations, and services.

📥 Example Input:

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

🏆 Expected Output:

Spring context initialized with automatically discovered beans.

🛠️ Use Cases:

• Defining entry point for a Spring Boot application.
• Reducing configuration boilerplate.
• Enabling component auto-discovery.
