    Spring Boot is a Java framework built on top of Spring that simplifies application development by providing features like auto-configuration, embedded servers, and starter dependencies. Below is a simple example of creating a Spring Boot Hello World application.

    Step 1: Maven Dependencies

    Add the following dependencies to your pom.xml file to include Spring Boot and its web starter.

    <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.1.2</version>
    <relativePath/>
    </parent>

    <dependencies>
    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    </dependencies>
    Copied!

    Step 2: Create the Main Application Class

    The @SpringBootApplication annotation marks the entry point of the Spring Boot application. This class initializes and runs the application.

    package com.example;

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

    @SpringBootApplication
    public class MainApplication {
    public static void main(String[] args) {
    SpringApplication.run(MainApplication.class, args);
    }
    }
    Copied!
    Why is Spring Boot important in Java application development?
    In the modern landscape of Java application development, building flexible and efficient APIs is of utmost importance. Spring Boot, a popular framework, simplifies the development of stand - alone, production - ready Spring applications.
