Understanding the Spring Petclinic application with a few diagrams
Running petclinic locally
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/
Or you can run it from Maven directly using the Spring Boot Maven plugin. If you do this it will pick up changes that you make in the project immediately (changes to Java source files require a compile as well - most people use an IDE for this):
In case you find a bug/suggested improvement for Spring Petclinic
Our issue tracker is available here: https://github.com/spring-projects/spring-petclinic/issues
In its default configuration, Petclinic uses an in-memory database (H2) which
gets populated at startup with data. The h2 console is automatically exposed at
and it is possible to inspect the content of the database using the
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_USER=petclinic -e MYSQL_PASSWORD=petclinic -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8
Further documentation is provided here.
Working with Petclinic in your IDE
The following items should be installed in your system:
- Java 8 or newer.
- git command line tool (https://help.github.com/articles/set-up-git)
- Your preferred IDE
- On the command line
git clone https://github.com/spring-projects/spring-petclinic.git
- Inside Eclipse or STS
File -> Import -> Maven -> Existing Maven project
Then either build on the command line
./mvnw generate-resources or using the Eclipse launcher (right click on project and
Run As -> Maven install) to generate the css. Run the application main method by right clicking on it and choosing
Run As -> Java Application.
- Inside IntelliJ IDEA
In the main menu, choose
File -> Open and select the Petclinic pom.xml. Click on the
CSS files are generated from the Maven build. You can either build them on the command line
or right click on the
spring-petclinic project then
Maven -> Generates sources and Update Folders.
A run configuration named
PetClinicApplication should have been created for you if you're using a recent Ultimate
version. Otherwise, run the application by right clicking on the
PetClinicApplication main class and choosing
- Navigate to Petclinic

Interesting Spring Petclinic branches and forks
The Spring Petclinic master branch in the main spring-projects GitHub org is the "canonical" implementation, currently based on Spring Boot and Thymeleaf. There are quite a few forks in a special GitHub org spring-petclinic. If you have a special interest in a different technology stack that could be used to implement the Pet Clinic then please join the community there.
Interaction with other open source projects
One of the best parts about working on the Spring Petclinic application is that we have the opportunity to work in direct contact with many Open Source projects. We found some bugs/suggested improvements on various topics such as Spring, Spring Data, Bean Validation and even Eclipse! In many cases, they've been fixed/implemented in just a few days. Here is a list of them:
|Spring JDBC: simplify usage of NamedParameterJdbcTemplate||SPR-10256 and SPR-10257|
|Bean Validation / Hibernate Validator: simplify Maven dependencies and backward compatibility||HV-790 and HV-792|
|Spring Data: provide more flexibility when working with JPQL queries||DATAJPA-292|
