Introduction to Spring Boot

Spring Boot is a powerful Java framework that makes it easy to build robust backend services. This post will introduce you to the basics of Spring Boot.

What is Spring Boot?

Spring Boot is a Java framework that allows you to build robust backend services with ease. It provides a number of features out of the box, such as auto-configuration, embedded servers, and production-ready metrics, that make it easy to build fast and scalable backend services.

@SpringBootApplication

public class Application {



    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);

    }



}

Why use Spring Boot?

Spring Boot is a great choice for building robust backend services because it provides a number of features that make it easy to build fast and scalable applications. Some of the key features of Spring Boot include:

• Auto-configuration: Spring Boot can automatically configure your application based on the dependencies you have in your classpath.
• Embedded servers: Spring Boot can run your application using an embedded server, such as Tomcat, Jetty, or Undertow.
• Production-ready metrics: Spring Boot can provide production-ready metrics, such as memory usage, garbage collection, and HTTP requests.

How to use Spring Boot

To use Spring Boot, you need to create a new Spring Boot project by running the following command:

spring init --name=my-app --dependencies=web my-app

This will create a new Spring Boot project in a directory called my-app. You can then navigate to the project directory and start the development server by running the following command:

cd my-app

./mvnw spring-boot:run

This will start the development server and open your Spring Boot application in your browser. You can then start building your application by creating new controllers, services, and repositories.
