In this post, we would like to suggest a free open-source project that is Spring Petclinic developed using Spring Boot for learning purposes. So go ahead, check out the source code, and have a hands-on experience on real-time project.

Spring Boot Project - Spring Pet clinic

This is a sample Spring Petclinic application developed by the Spring team to demonstrates the Spring framework related features.

Running petclinic locally

Petclinic is a https://spring.io/guides/gs/spring-boot[Spring Boot] application built using https://spring.io/guides/gs/maven/[Maven]. You can build a jar file and run it from the command line:

git clone https://github.com/spring-projects/spring-petclinic.git
cd spring-petclinic
./mvnw package
java -jar target/*.jar

You can then access petclinic here: http://localhost:8080/

Database configuration

In its default configuration, Petclinic uses an in-memory database (HSQLDB) which gets populated at startup with data. A similar setup is provided for MySql in case a persistent database configuration is needed. Note that whenever the database type is changed, the app needs to be run with a different profile: spring.profiles.active=mysql for MySql.

You could start MySql locally with whatever installer works for your OS, or with docker:

docker run -e MYSQL_ROOT_PASSWORD=petclinic -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8
