Spring PetClinic Sample Application Build Status

Understanding the Spring Petclinic application with a few diagrams

See the presentation here

Running petclinic locally

    git clone https://github.com/spring-projects/spring-petclinic.git
    cd spring-petclinic
    ./mvnw tomcat7:run

You can then access petclinic here: http://localhost:9966/petclinic/

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

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 data-access.properties file needs to be updated and the mysql-connector-java artifact from the pom.xml needs to be uncommented.

You may start a MySql database with docker:

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

Working with Petclinic in Eclipse/STS


The following items should be installed in your system:

Note: when m2e is available, there is an m2 icon in Help -> About dialog. If m2e is not there, just follow the install process here: http://eclipse.org/m2e/download/


1) In the command line

git clone https://github.com/spring-projects/spring-petclinic.git

2) Inside Eclipse

File -> Import -> Maven -> Existing Maven project

Java Config
Java Config branch Petclinic uses XML configuration by default. In case you'd like to use Java Config instead, there is a Java Config branch available here. Thanks to Antoine Rey for his contribution.

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:

Name Issue
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
Eclipse: validation bug when working with .tag/.tagx files (has only been fixed for Eclipse 4.3 (Kepler)). See here for more details. STS-3294
