Create Spring Boot Application using Spring Initializr

Published
Spring Initializr is a web-based tool that simplifies the setup of Spring Boot projects by generating pre-configured templates with necessary dependencies. It provides a quick and efficient way to start a new Spring Boot application. Spring Boot itself is a powerful framework built on the Spring Framework, designed for creating stand-alone, production-ready applications with minimal configuration.
To create a Spring Boot application, you can either start from the Spring Initializr website or select "New Project with Spring Boot" in IntelliJ IDEA. Configure your project by selecting the required options:
  • Project Type: Choose Maven or Gradle based on your preference.
  • Language: Select Java (you can also choose Kotlin or Groovy if needed).
  • Spring Boot Version: Choose the latest stable version. For IntelliJ IDEA, it will automatically select the latest version.
  • Project Metadata:
    • Group: Group ID for your project, usually in reverse domain format (e.g., com.ms29).
    • Artifact: Artifact ID for your project (e.g., event-registration).
    • Name: Name of your project (e.g., Event Registration).
    • Description: Description of your project.
    • Package Name: Package name for your project (e.g., com.ms29.event.registration).
    • Java: Choose the Java version (e.g., 21).
Spring Boot Project Configuration
Once you have configured your project, add the necessary dependencies such as:
  • Spring Web for building web applications.
  • PostgreSQL Driver for PostgreSQL database. You can choose other databases like MySQL or H2 based on your requirements.
  • Spring Data JPA for database interaction.
  • Spring Security for authentication and authorization.
  • Spring Actuator to monitor and manage application health and performance.
  • Spring Boot DevTools for faster development.
  • Lombok to reduce boilerplate code (such as getters, setters, constructors, etc.).
  • Validation to apply validation constraints on your models.
  • Thymeleaf templating engine for rendering HTML pages.
Spring Boot Project Dependencies
After adding the dependencies, click on the "Generate" button to download the project zip file. Extract the zip file and open the project in your favorite IDE. For IntelliJ IDEA, project will be set up on your local machine. You can start building your Spring Boot application by creating controllers, services, and repositories.
We will discuss how to configure the Spring Boot application, create REST APIs, and interact with the database in the upcoming articles. Please keep an eye on the website for more updates.
