Hilla implementation of Spring PetClinic

This is a Hilla implementation of the Spring PetClinic sample project: https://github.com/spring-projects/spring-petclinic

Hilla is a full-stack React framework for Spring. It includes:

• A large library of UI components
• Reactive TypeScript frontend using React
• Type-safe server communication and TS type generation based on Java

Running petclinic locally

Petclinic is a Spring Boot application built using Maven. 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

You can then access petclinic here: http://localhost:8080/

NOTE: Windows users should set git config core.autocrlf true to avoid format assertions failing the build (use --global to set that flag globally).

Database configuration

In its default configuration, Petclinic uses an in-memory database (H2) which gets populated at startup with data. The h2 console is automatically exposed at http://localhost:8080/h2-console and it is possible to inspect the content of the database using the jdbc:h2:mem:testdb url.

A similar setup is provided for MySql in case a persistent database configuration is needed. Note that whenever the database type is changed, the app needs to be run with a different profile: spring.profiles.active=mysql for MySql.

You could start MySql locally with whatever installer works for your OS, or with docker:

docker run -e MYSQL_USER=petclinic -e MYSQL_PASSWORD=petclinic -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8

Further documentation is provided here.

Working with Petclinic in your IDE

Prerequisites

The following items should be installed in your system:

• Java 8 or newer (full JDK not a JRE).
• git command line tool (https://help.github.com/articles/set-up-git)
• Your preferred IDE
  • Spring Tools Suite (STS)
  • IntelliJ IDEA
  • VS Code

Steps:

1. On the command line

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

2. 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.

3. 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'.

4. Navigate to Petclinic

   Visit http://localhost:8080 in your browser.

Interesting Spring Petclinic branches and forks

The Spring Petclinic "main" branch in the spring-projects GitHub org is the "canonical" implementation, currently based on Spring Boot and Thymeleaf. There are quite a few forks in a special GitHub org spring-petclinic. If you have a special interest in a different technology stack that could be used to implement the Pet Clinic then please join the community there.
