spring-starter-terminal VS initializr

There is probably much more that could be covered, but I think this is the most important once you know the basics. If you are new to Maven, suggest starting with an introduction like this. The guide covers creating projects as well, but many modern frameworks have easier and better generators. Spring Boot have its own initializer website, and I've made a CLI version. Quarkus also have a nice web UI you can use to create new projects.

Let's do something slightly different by demonstrating the usage of volumes and Ansible roles during build. It's not unusual to want to package an application into a container, and for simplicity we put it into the same directory as the playbook itself (so we can use the playbook_dir variable). To not make this example too advanced, we simply use a Spring Boot application made from Spring Initializr without any changes (if you prefer a terminal UI, there is one for that too). We'll use geerlingguys java role to setup Java to not boggle down the example with Java setup.

The best way, for generating a ready-to-run application in Java you can use the Spring Boot Initializr tool.

curl --location 'https://start.spring.io/starter.zip?type=maven-project&language=java&bootVersion=3.2.2&baseDir=ms-xcoffee&groupId=com.xcoffee&artifactId=ms-xcoffee&name=ms-xcoffee&description=Demo%20project%20for%20Spring%20Boot&packageName=com.xcoffee.ms-xcoffee&packaging=jar&javaVersion=21&dependencies=webflux%2Clombok%2Cvalidation' | tar -xzvf -

In this segment we will create a basic Spring boot app from Spring Initializer. Add the below dependencies:

Add the following MongoDB dependencies in your pom.xml or use spring initializer and select the Spring Data MongoDB dependency:

I created all of these applications using start.spring.io's REST API and HTTPie.

An easy way to create the skeleton project is to visit Spring Initializr, I set the Project to Gradle - Groovy, Language to Java, and add Spring Web dependency. Then it's just to generate the project and unpack it.

Create a new Spring Boot application using the Spring Initializr. You can use the web version or the curl command below. Use the default for most of the options. For the dependencies, select web, and okta. For the build tool, select Gradle.

I will start with a simple example of a cloud function, which is the same as a rest endpoint in the classical spring boot web application. You can create a project from your favorite IDE or from Spring Initliazr.
