Spring PetClinic Sample Application

This is a fork of https://github.com/spring-projects/spring-petclinic to be used for the DP1 course. The main changes that have been performed were:

Trimming several parts of the application to keep the example low
Reorganize some parts of the code according to best practices introduced in the course

Running petclinic locally

Petclinic is a Spring Boot application built using Maven. You can build a jar file and run it from the command line:

git clone https://github.com/gii-is-DP1/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):

./mvnw spring-boot:run

Database configuration

In its default configuration, Petclinic uses an in-memory database (H2) which gets populated at startup with data.

Prerequisites

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

Steps:

On the command line

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 Open button.

CSS files are generated from the Maven build. You can either build them on the command line ./mvnw generate-resources or right click on the spring-petclinic project then Maven -> Generates sources and Update Folders.
