Spring PetClinic Sample Application

Understanding the Spring Petclinic application with a few diagrams

See the presentation here

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/cleankod/spring-petclinic
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

Working with Petclinic in your IDE

Prerequisites

The following items should be installed in your system:

• JDK 11 or newer.
• git command line tool (https://help.github.com/articles/set-up-git)
• Your preferred IDE
  • IntelliJ IDEA
  • Eclipse with the m2e plugin. 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: https://www.eclipse.org/m2e/
  • Spring Tools Suite (STS)
  • VS Code

Steps:

1. 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.

   A run configuration named PetClinicApplication should have been created for you if you're using a recent Ultimate version. Otherwise, run the application by right clicking on the PetClinicApplication main class and choosing Run 'PetClinicApplication'.
