# Spring PetClinic Sample Application [![Build Status](https://travis-ci.org/spring-projects/spring-petclinic.png?branch=main)](https://travis-ci.org/spring-projects/spring-petclinic/)
## Understanding the Spring Petclinic application with a few diagrams

## Running petclinic locally
Petclinic is a [Spring Boot](https://spring.io/guides/gs/spring-boot) application built using [Maven](https://spring.io/guides/gs/maven/). You can build a jar file and run it from the command line:

## 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:

## Working with Petclinic in your IDE
### 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
* 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](https://spring.io/tools) (STS)
* IntelliJ IDEA
* [VS Code](https://code.visualstudio.com)

### 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
```
1. On the command line
```
git clone https://github.com/spring-projects/spring-petclinic.git
```
2. Inside Eclipse or STS
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`.
```
File -> Import -> Maven -> Existing Maven project
```
3) Inside IntelliJ IDEA
In the main menu, choose `File -> Open` and select the Petclinic [pom.xml](pom.xml). Click on the `Open` button.
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`.
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`.
3. Inside IntelliJ IDEA
In the main menu, choose `File -> Open` and select the Petclinic [pom.xml](pom.xml). Click on the `Open` button.
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'`.

## 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.
