Spring Boot version of the Spring PetClinic Sample Application

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
	git checkout angularjs
	./mvnw clean install
	cd spring-petclinic-server
	./mvnw spring-boot:run

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 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

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

Client-side Architecture

Compared to the standard Petclinic based on JSP pages, this SpringBoot AngularJS Petclinic is splitted in 2 modules - a client module and a server module:

• springboot-petclinic-client : static resources (images, fonts, style, angular JS code) packaged as a webjar.
• springboot-petclinic-server : Spring MVC REST API and an index.html template

Looking for something in particular?

Spring Boot Configuration
The Main Class	PetClinicApplication.java
Properties Files	application.properties application-dev.properties application-prod.properties
Caching	Use JCache with EhCache CacheConfig.java ehcache.xml
Homepage	Map root context to the index.html template WebConfig.java ehcache.xml

Front-end module	Files
Node and NPM	The frontend-maven-plugin plugin downloads/installs Node and NPM locally then runs Bower and Gulp
Bower	JavaScript libraries are defined by the manifest file bower.json
Gulp	Tasks automated by Gulp: minify CSS and JS, generate CSS from LESS, copy other static resources
AngularJS	app.js, controllers and templates

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
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
