# Spring Boot version of the Spring PetClinic Sample Application [](https://travis-ci.org/spring-projects/spring-petclinic/)
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

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.
