Spring-Boot CXF JAXRS QuickStart

This example demonstrates how you can use Apache CXF with Spring Boot based on a fabric8 Java base image.

The quickstart uses Spring Boot to configure a little application that includes a CXF JAXRS endpoint with Swagger enabled.

Building

The example can be built with

mvn clean install

Running the example locally

The example can be run locally using the following Maven goal:

mvn spring-boot:run

Running the example in Kubernetes

It is assumed a running Kubernetes platform is already running. If not you can find details how to get started.

Assuming your current shell is connected to Kubernetes or OpenShift so that you can type a command like

kubectl get pods

or for OpenShift

oc get pods

Then the following command will package your app and run it on Kubernetes:

mvn fabric8:run

The output log will give the URL to access the endpoint, something like

[INFO] F8:[SVC] spring-boot-cxf-jaxrs: http://192.168.64.7:32225

You will need to append the context-path to access the JAX-RS service so the url is something like

http://192.168.64.7:32225/services/helloservice/sayHello/

To list all the running pods:

oc get pods

Then find the name of the pod that runs this quickstart, and output the logs from the running pods with:

oc logs <name of pod>

You can also use the fabric8 developer console to manage the running pods, and view logs and much more.

To access the endpoint, use the host and port from the output log when run mvn fabric8:run

http://192.168.64.7:32225/services/helloservice/sayHello/FIS will display "Hello FIS, Welcome to CXF RS Spring Boot World!!!"

http://192.168.64.7:32225/services/helloservice/swagger.json will return a Swagger JSON description of services.

Integration Testing

The example includes a fabric8 arquillian Kubernetes Integration Test. Once the container image has been built and deployed in Kubernetes, the integration test can be run with:

mvn test -Dtest=*KT

The test is disabled by default and has to be enabled using -Dtest. Integration Testing and Fabric8 Arquillian Extension provide more information on writing full fledged black box integration tests for Kubernetes.
