This backend version of the Spring Petclinic application only provides a REST API. There is no UI. The spring-petclinic-angular project is a Angular front-end application which consumes the REST API.
See the presentation of the Spring Petclinic Framework version
git clone https://github.com/spring-petclinic/spring-petclinic-rest.git
cd spring-petclinic-rest
./mvnw spring-boot:rundocker run -p 9966:9966 springcommunity/spring-petclinic-restYou can then access petclinic here: http://localhost:9966/petclinic/
There is an actuator health check route as well:
You can reach the Swagger UI with this URL (after application start): http://localhost:9966/petclinic/.
You then can get the Open API description reaching this URL: localhost:9966/petclinic/v3/api-docs.

In its default configuration, Petclinic uses an in-memory database (HSQLDB) which gets populated at startup with data.
Similar setups are provided for MySql and PostgreSQL in case a persistent database configuration is needed. However, to populate them with sample data, you should follow additional instructions from either src/main/resources/db/mysql/petclinic_db_setup_mysql.txt (for MySQL) or src/main/resources/db/postgresql/petclinic_db_setup_postgresql.txt (for PostgreSQL) file.
To run Petclinic locally using persistent database, it is also needed to change profile defined in application.properties file.
For MySQL database, it is needed to change param hsqldb to mysql in the following line of application.properies file:
spring.profiles.active=hsqldb,spring-data-jpaBefore doing this, it would be good to check properties defined in application-mysql.properties file:
spring.datasource.url = jdbc:mysql://localhost:3306/petclinic?useUnicode=true
spring.datasource.username=pc
spring.datasource.password=petclinic
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database=MYSQL
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=noneYou may also start a MySql database with Docker:
docker run --name mysql-petclinic -e MYSQL_ROOT_PASSWORD=petclinic -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8For PostgeSQL database, it is needed to change param hsqldb to postgresql in the following line of application.properties file:
spring.profiles.active=hsqldb,spring-data-jpaBefore doing this, it would be good to check properties defined in application-postgresql.properties file:
spring.datasource.url=jdbc:postgresql://localhost:5432/petclinic
spring.datasource.username=postgres
spring.datasource.password=petclinic
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database=POSTGRESQL
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=noneYou may also start a Postgres database with Docker:
docker run --name postgres-petclinic -e POSTGRES_PASSWORD=petclinic -e POSTGRES_DB=petclinic -p 5432:5432 -d postgres:9.6.0This API is built following some API First approach principles.
It is specified through the OpenAPI. It is specified in this file.
Some of the required classes are generated during the build time. Here are the generated file types:
- DTOs
- API template interfaces specifying methods to override in the controllers
To see how to get them generated you can read the next chapter.
Some of the required classes are generated during the build time using maven or any IDE (e.g., IntelliJ Idea or Eclipse).
All of these classes are generated into the target/generated-sources folder.
Here is a list of the generated packages and the corresponding tooling:
| Package name | Tool |
|---|---|
| org.springframework.samples.petclinic.mapper | MapStruct |
| org.springframework.samples.petclinic.rest.dto | OpenAPI Generator maven plugin |
To get both, you have to run the following command:
mvn clean install
In its default configuration, Petclinic doesn't have authentication and authorization enabled.
In order to use the basic authentication functionality, turn in on from the application.properties file
petclinic.security.enable=trueThis will secure all APIs and in order to access them, basic authentication is required. Apart from authentication, APIs also require authorization. This is done via roles that a user can have. The existing roles are listed below with the corresponding permissions
OWNER_ADMIN->OwnerController,PetController,PetTypeController(getAllPetTypesandgetPetType),VisitControllerVET_ADMIN->PetTypeController,SpecialityController,VetControllerADMIN->UserController
There is an existing user with the username admin and password admin that has access to all APIs.
In order to add a new user, please make POST /api/users request with the following payload:
{
"username": "secondAdmin",
"password": "password",
"enabled": true,
"roles": [
{ "name" : "OWNER_ADMIN" }
]
}The following items should be installed in your system:
- Maven 3 (https://maven.apache.org/install.html)
- git command line tool (https://help.github.com/articles/set-up-git)
- Eclipse with the m2e plugin (m2e is installed by default when using the STS (http://www.springsource.org/sts) distribution of Eclipse)
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: http://eclipse.org/m2e/download/
- Eclipse with the mapstruct plugin installed.
- In the command line
git clone https://github.com/spring-petclinic/spring-petclinic-rest.git- Inside Eclipse

This application uses Google Jib to build an optimized Docker image into the Docker Hub repository.
The pom.xml has been configured to publish the image with a the springcommunity/spring-petclinic-restimage name.
Command line to run:
mvn compile jib:build -X -DjibSerialize=true -Djib.to.auth.username=xxx -Djib.to.auth.password=xxxxxThe Spring Petclinic master branch in the main spring-projects GitHub org is the "canonical" implementation, currently based on Spring Boot and Thymeleaf.
This spring-petclinic-rest project is one of the several forks hosted 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.
