Creating a Simple Spring Boot Application

Step-by-step Guide to Creating Your First Spring Boot Application:

1. Initialize a Spring Boot Project:

   • Use Spring Initializr to generate a new project.

   • Select project type (Maven/Gradle), language (Java), and Spring Boot version.

   • Add dependencies: Spring Web.

2. Import the Project into Your IDE:

   • Open the project in your chosen IDE.

   • Familiarize yourself with the project structure.

3. Create a Main Application Class:

   • This class will contain the main method annotated with @SpringBootApplication.

    package com.example.demo;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

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

4. Run the Application:

   • Use your IDE to run the application or execute mvn spring-boot:run in the terminal.

   • Access the application at http://localhost:8080.
