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

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 tomcat7: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 run with profile defined in main pom.xml file.

For MySQL database, it is needed to run with 'MySQL' profile defined in main pom.xml file.

    ./mvnw tomcat7:run -P MySQL

Before do this, would be good to check properties defined in MySQL profile inside pom.xml file.

    <properties>
        <jpa.database>MYSQL</jpa.database>
        <jdbc.driverClassName>com.mysql.jdbc.Driver</jdbc.driverClassName>
        <jdbc.url>jdbc:mysql://localhost:3306/petclinic?useUnicode=true</jdbc.url>
        <jdbc.username>root</jdbc.username>
        <jdbc.password>petclinic</jdbc.password>
    </properties>

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 PostgreSQL database, it is needed to run with 'PostgreSQL' profile defined in main pom.xml file.

    ./mvnw tomcat7:run -P PostgreSQL

Before do this, would be good to check properties defined in PostgreSQL profile inside pom.xml file.

			<properties>
                <jpa.database>POSTGRESQL</jpa.database>
                <jdbc.driverClassName>org.postgresql.Driver</jdbc.driverClassName>
                <jdbc.url>jdbc:postgresql://localhost:5432/petclinic</jdbc.url>
                <jdbc.username>postgres</jdbc.username>
                <jdbc.password>petclinic</jdbc.password>
            </properties>

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:

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

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
