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-angular2 project is a 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
	./mvnw spring-boot:run

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

Swagger REST API documentation presented here:

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.driverClassName = com.mysql.jdbc.Driver
spring.datasource.username=root 
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 applcation.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.driverClassName=org.postgresql.Driver
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

Working with Petclinic in Eclipse/STS

prerequisites

The following items should be installed in your system:

• Maven 3 (http://www.sonatype.com/books/mvnref-book/reference/installation.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/

Steps:

1. In the command line

git clone https://github.com/spring-petclinic/spring-petclinic-rest.git

2. Inside Eclipse

File -> Import -> Maven -> Existing Maven project

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. Here is a list of them:

Name	Issue
Spring JDBC: simplify usage of NamedParameterJdbcTemplate	SPR-10256 and SPR-10257
Bean Validation / Hibernate Validator: simplify Maven dependencies and backward compatibility	HV-790 and HV-792
Spring Data: provide more flexibility when working with JPQL queries	DATAJPA-292
Dandelion: improves the DandelionFilter for Jetty support	113
