How to Build a Spring Boot Application

Spring Boot is a popular Java framework used for building web applications quickly and easily. With Spring Boot, developers can quickly create robust and scalable applications without having to worry about configuring every aspect of the application. In this article, we will walk through the steps needed to build a Spring Boot application.


  • Java JDK 8 or higher installed
  • Maven or Gradle installed
  • An Integrated Development Environment (IDE) such as IntelliJ IDEA or Eclipse installed

Step 1: Create a new Spring Boot project

To create a new Spring Boot project, we can use Spring Initializr, which is a web-based tool that generates a basic project structure for us. We can access it by going to in a web browser.

Once we are on the Spring Initializr page, we can specify the project details such as the project name, package name, and dependencies. In this example, we will use Maven as the build tool and add the Spring Web dependency, which is necessary for building a web application.

After specifying the project details, we can click on the Generate button to download a zip file containing the project structure.

Step 2: Import the project into the IDE

Once we have downloaded the project, we can import it into our IDE. In IntelliJ IDEA, we can do this by selecting File > New > Project from Existing Sources and selecting the downloaded project folder.

Step 3: Create a RESTful API endpoint

To create a RESTful API endpoint, we can create a new Java class in the src/main/java/com/example/demo/ directory. In this example, we will create a new class called HelloWorldController.

package com.example.demo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

public class HelloWorldController {

public String helloWorld() {
return "Hello, World!";

This class defines a RESTful endpoint at the root URL (/) that returns a simple message.

Step 4: Run the application

To run the application, we can use Maven to build and run the project. In IntelliJ IDEA, we can do this by opening the Maven panel on the right-hand side of the screen and selecting the demo > Lifecycle > install option.

After the build is complete, we can run the application by right-clicking on the DemoApplication class in the src/main/java/com/example/demo/ directory and selecting the Run option.

Step 5: Test the API endpoint

Once the application is running, we can test the API endpoint by opening a web browser and navigating to http://localhost:8080/. We should see the message "Hello, World!" displayed in the browser.

Additional Steps: Adding More Functionality
In addition to creating a simple RESTful API endpoint, we can also add more functionality to our Spring Boot application. For example, we can add a database by adding the Spring Data JPA dependency and defining a data model, or we can add authentication and authorization by adding the Spring Security dependency.

In this article, we have seen how easy it is to build a Spring Boot application. By following these simple steps, we can create a robust and scalable web application with minimal configuration. We encourage you to experiment with the Spring Boot framework and explore the various features and capabilities it has to offer.
