Spring Boot is a part of the larger Spring Framework ecosystem which is known for its comprehensive programming and configuration model for the modern Java-based enterprise applications. Spring Boot has emerged as a go-to framework for creating REST APIs, microservices, and web applications with less configuration. It eliminates the need for boilerplate code and configuration by offering opinionated defaults and auto-configuration, enabling developers to focus on writing business logic rather than wrestling with setup details. Spring Boot’s ability to run applications on embedded servers like Tomcat or Jetty further enhances its appeal, allowing developers to create production-ready applications quickly and efficiently. Spring Boot simplifies the creation of Spring applications by offering several key features: Before starting with Spring Boot, ensure that you have the following:

After creating the project, extract the folder and open it in IntelliJ IDEA. The file structure should look like this: HelloController.java: This class defines a simple REST API endpoint that returns a greeting message. This section describes how to develop a small “Hello World!” web application that highlights some of Spring Boot’s key features. You can choose between Maven or Gradle as the build system. The spring.io website contains many “Getting Started” guides that use Spring Boot.

If you need to solve a specific problem, check there first. You can shortcut the steps below by going to start.spring.io and choosing the "Web" starter from the dependencies searcher. Doing so generates a new project structure so that you can start coding right away. Check the start.spring.io user guide for more details. Before we begin, open a terminal and run the following commands to ensure that you have a valid version of Java installed: If you want to use Maven, ensure that you have Maven installed:

Spring Boot is a Java framework built on top of Spring that simplifies application development. It eliminates boilerplate code with auto-configuration. Spring Boot comes with an embedded server, making applications production ready out of the box. It supports web apps, REST APIs, microservices, security and seamless cloud deployment. In this section, you’ll learn what Spring Boot is, how it differs from Spring and Spring MVC and how to set up your development environment to quickly build and run your first application. To work effectively with Spring Boot, a solid understanding of core Java and essential Spring concepts is important.

Knowledge of build tools such as Maven or Gradle, along with databases and SQL for JPA/Hibernate integration, will also help in building robust applications.
