With maven command line

git clone https://github.com/spring-petclinic/spring-petclinic-rest.git
cd spring-petclinic-rest
./mvnw spring-boot:run

With Docker

docker run -p 9966:9966 springcommunity/spring-petclinic-rest

You can then access petclinic here: http://localhost:9966/petclinic/

There are actuator health check and info routes as well:

OpenAPI REST API documentation presented here (after application start):

You can reach the swagger UI with this URL http://localhost:9966/petclinic/.

You then can get the Open API description reaching this URL localhost:9966/petclinic/v3/api-docs.

Database configuration

In its default configuration, Petclinic uses an in-memory database (HSQLDB) which gets populated at startup with data. A similar setups is provided for MySql and PostgreSQL in case a persistent database configuration is needed. To run petclinic locally using persistent database, it is needed to change profile defined in application.properties file.

For MySQL database, it is needed to change param "hsqldb" to "mysql" in string

spring.profiles.active=hsqldb,spring-data-jpa

defined in application.properties file.

Before do this, 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=none

You 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:5.7.8

For PostgeSQL database, it is needed to change param "hsqldb" to "postgresql" in string

spring.profiles.active=hsqldb,spring-data-jpa

defined in application.properties file.

Before do this, 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=none

You 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:9.6.0

API First Approach

This 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.

Generated code

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

Security configuration

In its default configuration, Petclinic doesn't have authentication and authorization enabled.

Basic Authentication

In order to use the basic authentication functionality, turn in on from the application.properties file

petclinic.security.enable=true

This 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 (getAllPetTypes and getPetType), VisitController
  • VET_ADMIN -> PetTypeController, SpecialityController, VetController
  • ADMIN -> 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 use the following API:

POST /api/users
{
    "username": "secondAdmin",
    "password": "password",
    "enabled": true,
    "roles": [
    	{ "name" : "OWNER_ADMIN" }
	]
}

Working with Petclinic in Eclipse/STS

prerequisites

The following items should be installed in your system:

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/

Steps:

  1. In the command line
git clone https://github.com/spring-petclinic/spring-petclinic-rest.git
  1. Inside Eclipse
File -> Import -> Maven -> Existing Maven project

Publishing a Docker image

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=xxxxx

Interesting Spring Petclinic forks

The 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.
