Approved by the Spring team, this repo is a fork of the spring-projects/spring-petclinic. It allows the Spring community to maintain a Petclinic version with a plain old Spring Framework configuration and with a 3-layer architecture (i.e. presentation --> service --> repository). The "canonical" implementation is now based on Spring Boot, Thymeleaf and aggregate-oriented domain.
Understanding the Spring Petclinic application with a few diagrams
See the presentation here (2017 update)
Running petclinic locally
git clone https://github.com/spring-petclinic/spring-framework-petclinic.git cd spring-framework-petclinic ./mvnw tomcat7:run-war
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-petclinic/spring-framework-petclinic/issues
In its default configuration, Petclinic uses an in-memory database (HSQLDB) which gets populated at startup with data. A similar setups is provided for MySql and PostgreSQL in case a persistent database configuration is needed. To run petclinic locally using persistent database, it is needed to run with profile defined in main pom.xml file.
For MySQL database, it is needed to run with 'MySQL' profile defined in main pom.xml file.
./mvnw tomcat7:run-war -P MySQL
Before do this, would be good to check properties defined in MySQL profile inside pom.xml file.
<properties> <jpa.database>MYSQL</jpa.database> <jdbc.driverClassName>com.mysql.cj.jdbc.Driver</jdbc.driverClassName> <jdbc.url>jdbc:mysql://localhost:3306/petclinic?useUnicode=true</jdbc.url> <jdbc.username>root</jdbc.username> <jdbc.password>petclinic</jdbc.password> </properties>
You may also start a MySql database with docker:
docker run --name mysql-petclinic -e MYSQL_ROOT_PASSWORD=petclinic -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8
For PostgreSQL database, it is needed to run with 'PostgreSQL' profile defined in main pom.xml file.
./mvnw tomcat7:run-war -P PostgreSQL
Before do this, would be good to check properties defined in PostgreSQL profile inside pom.xml file.
<properties> <jpa.database>POSTGRESQL</jpa.database> <jdbc.driverClassName>org.postgresql.Driver</jdbc.driverClassName> <jdbc.url>jdbc:postgresql://localhost:5432/petclinic</jdbc.url> <jdbc.username>postgres</jdbc.username> <jdbc.password>petclinic</jdbc.password> </properties>
You may also start a Postgres database with docker:
docker run --name postgres-petclinic -e POSTGRES_PASSWORD=petclinic -e POSTGRES_DB=petclinic -p 5432:5432 -d postgres:9.6.0
Working with Petclinic in Eclipse/STS
The following items should be installed in your system:
- Maven 3 (http://www.sonatype.com/books/mvnref-book/reference/installation.html)
- git command line tool (https://help.github.com/articles/set-up-git)
- Eclipse with the m2e plugin (m2e is installed by default when using the STS (http://www.springsource.org/sts) distribution of Eclipse)
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/
- In the command line
git clone https://github.com/spring-petclinic/spring-framework-petclinic.git
- Inside Eclipse
File -> Import -> Maven -> Existing Maven project

|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|

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|
|Dandelion: improves the DandelionFilter for Jetty support||113|
