Craft Demo

• Fork, build, run this github repo.
• Create a webservice endpoint to return a list of pets given an ownerId
• Visit currently is not associated with a vet. Add an association between visit and vet (a visit maps to a vet). Create a new webservice endpoint that returns all pets that has visited a vet
• Send a link to your fork to the interviewer which should include a PR to master with your changes.

REST version of Spring PetClinic Sample Application (spring-framework-petclinic extend )

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 5 front-end application witch consumes the REST API.

Understanding the Spring Petclinic application with a few diagrams

See the presentation here

Running petclinic locally

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

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

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

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
