Installation of Spring Boot

Introduction

Spring Boot is a popular open-source framework developed by Pivotal Technologies that simplifies the setup and development of new Spring applications. It takes an opinionated view of building production-ready Spring applications, allowing developers to quickly get up and running with minimal configuration.

In this tutorial, we will guide you through the process of installing and setting up Spring Boot on your system. Whether you are a beginner or an intermediate developer, this tutorial will provide you with the necessary steps to start developing Spring Boot applications.

Concept

Spring Boot simplifies the initial setup and development of new Spring applications by providing default configurations for common tasks such as embedded servers, security, and data access. It uses convention over configuration, which means it automatically configures your application based on the dependencies you add.

To use Spring Boot, you need to have Java Development Kit (JDK) installed on your system. Additionally, you can use tools like Maven or Gradle for dependency management and building your applications.

Examples

Step 1: Install JDK

Spring Boot requires a compatible version of the Java Development Kit (JDK). You can download and install the latest version from the Oracle website or use an open-source distribution like OpenJDK.

Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537)
Maven home: /usr/local/apache-maven
Java version: 17.0.1, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "12.3.1", arch: "x86_64", family: "mac"

Step 3: Install Spring Boot CLI

The Spring Boot Command Line Interface (CLI) is a tool that allows you to quickly prototype and test Spring Boot applications from the command line.

This will generate a new directory called my-spring-boot-app with a basic Spring Boot project structure.

Step 5: Run Your Application

Navigate to your project directory and run the application using Maven or Gradle.

$ cd my-spring-boot-app
$ mvn spring-boot:run

You should see output indicating that the application is running, typically on port 8080.
