spring-petclinic VS initializr

Here is a good repository to look at as you make progress. Good luck!

I like Spring's petclinic https://github.com/spring-projects/spring-petclinic

For the sake of demonstration, I'm going to use the same project I've used in my post about Omnipytent - the Java Sprint example project PetClinic.

"The Spring Pet Clinic" is well explained and obviously well designed and coded as an official Spring projet : https://github.com/spring-projects/spring-petclinic

For this OpenTelemetry Java example, we’ll be using the Spring Pet Clinic project, to save you some time setting up an example project.

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.

I would advise everyone to go the extra mile and update their entire spring boot version to the latest appropriate version. To find out what that is, simply go to https://start.spring.io.
