Spring PetClinic Sample Application

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
	mvn 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

Working with Petclinic in Eclipse/STS

prerequisites

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/

Steps:

1. In the command line

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

2. Inside Eclipse

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

XML Configuration
XML Configuration	This javaconfig branch uses Java Configuration. In case you'd like to use the XML configuration instead, there the master branch is available here. XML remains the default configuration for Spring Petclinic.

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
