Create a Spring Boot Gradle Application with Spring Initializr in Intellij

by


Hello Friends!, today we are going to learn a step-by-step process to create Spring Boot Gradle application using Spring Initializr in Intellij.

you can check our other post on the Maven project, on how to create Spring Boot Application using the below ways.

Using Spring Initializr.

Application in STS.

Application with Eclipse and Maven manually

This is a simple process to create a Spring Boot application as Gradle Project. we will use Spring Initializr tool to bootstrap our application using Spring MVC.

Create Project on Spring Initializr as Gradle Project

goto https://start.spring.io

This image has an empty alt attribute; its file name is start.spring.io_.png

Set Project metadata as show in image.

  • Project : Gradle Project
  • Group : com.gyanideveloper.springboot
  • Artifact : user-service
  • Name : user-service

Project should be Gradle Project as we are developing a Gradle based Spring Boot application in this tutorial.

click on ADD DEPENDENCIES button or press CTRL + B on keyboard.search and add Spring Web starter,Spring Boot Actuator, Spring Boot DevTools as dependency  as shown in the image.

we can add multiple dependencies as we required in our application. we can click on EXPLORE button or press CTRL + SPACE on the keyboard to check the application structure

click on GENERATE button or press CTRL+ ENTER on the keyboard, This would download a ZIP file to your local machine. Unzip the zip file and extract it to a folder.

Open Spring Boot Application in IntelliJ.

choose File -> Open navigate to the path where you extracted the ZIP file and select that folder as shown below and click on OK button.

Import project from gradle click on OK button

Your project will get open in IntelliJ and it takes some time to initialize and Gradle to download the dependencies.

Run Spring Boot Application

our project structure look like below.

you can run spring boot application in multiple way.such as using Toolbar run or using main class, we are using here toolbar Run.

choose run -> run.. as shown below.

select Main class Name as shown as below

It will take some time and application will start.

It start your Spring Boot application on port number 8080 , we can find console log as below.

If the application fails to start because the port is in use. please check our How to Change the Default Port in Spring Boot post for more details.
