Build Restful CRUD API for a simple Note-Taking application using Spring Boot, Database (H2, MySQL), JPA and Hibernate.
-
Java - 1.8.x
-
Maven - 3.x.x
1. Clone the application
git clone https://github.com/cmoulliard/spring-boot-jpa-rest.git2. Build and run the app using maven
You can run the app using the spring-boot maven plugin
mvn clean spring-boot:run -Dspring.profiles.active=local -Ph2The app will start running at http://localhost:8080.
3. Explore Rest APIs
The app defines following CRUD APIs.
GET /api/notes
POST /api/notes
GET /api/notes/{noteId}
PUT /api/notes/{noteId}
DELETE /api/notes/{noteId}
You can test them using postman or any other rest client such as curl.
curl -k http://localhost:8080/api/notes
curl -k -H "Content-Type: application/json" -X POST -d '{"title":"My first note","content":"Spring Boot is awesome!"}' http://localhost:8080/api/notes
curl -k http://localhost:8080/api/notes/14. Access the H2 Web Console
Open your web browser at the following address http://localhost:8080/h2-console and log on using as username sa, database jdbc:h2:mem:DEMO
- Create first a MySQL service
cf create-service cleardb spark mysql-notes-db - Deploy the Spring boot application without launching it
cf push --no-start - Bind the service and start the application
cf bs sb-db-rest mysql-notes-db- Start the application
cf start sb-db-rest- Test the service
curl -k https://sb-db-rest.cfapps.io/api/notes
curl -k -H "Content-Type: application/json" -X POST -d '{"title":"My first note","content":"Spring Boot is awesome!"}' https://sb-db-rest.cfapps.io/api/notes
curl -k https://sb-db-rest.cfapps.io/api/notes/1Prerequisite : The Ansible Service Broker must be installed locally as this feature is not yet available online ! More info about the Kubernetes ServiceCatalog concepts are available here
- Start MiniShift with the experimental feature, OCP >= v3.7.1 and install Ansible Service Broker

The process to download the repository of the catalog and deploy it locally could take time !

...- Create a new namespace to host the project
oc new-project demo-spring-db- Deploy the MySQL Service within the namespace created
The serviceInstance represents a provisioned instance of the MySQL ClusterServiceClass. When a new ServiceInstance resource is created, the Service Catalog controller will connect to the appropriate Service Broker and instruct it to provision the service instance.
oc create -f openshift/mysql_serviceinstance.yml- Create a new app on the cloud platform
oc new-app -f openshift/spring-boot-db-notes_template.yml- Start the build using project's source
oc start-build spring-boot-db-notes-s2i --from-dir=. --follow- Bind the credentials of the ServiceInstances to a Secret
The following file will allow to access the credentials of the MySQL ServiceInstance. Upon creation, the Service Catalog controller will create a Kubernetes Secret containing connection details and credentials for the Service Instance, which can be mounted into Pods.
oc create -f openshift/mysql-secret_servicebinding.yml- Mount the secret within the Deploymentconfig
oc env --from=secret/spring-boot-notes-mysql-binding dc/spring-boot-db-notes- Wait till the pod is recreated and then test the service
export HOST=$(oc get route/spring-boot-db-notes -o jsonpath='{.spec.host}')

curl -k -H "Content-Type: application/json" -X POST -d '{"title":"My first note","content":"Spring Boot is awesome!"}' $HOST/api/notes
