This article demonstrates how to get a SOAP web service up and running really quickly using Camel, Spring Boot and CXF. All based on the tremendous Fuse Integration Services 2.0 for Openshift.
Sometimes using SOAPUI for mocking Web Services is fine, however, quite often now we need everything to run IN the environment. Running services on your desktop doesn’t cut it anymore. So when we are performing integration testing it is always useful to have code running in the environment that will act more or less like the “real thing”.
Say for example we have a running SOAP webservice, and we harvest number of static responses we can use for this purpose, putting together a mock is pretty easy stuff thanks to the archetypes and the power of Camel.
Create our project
To start with ensure your maven repositories are configured, and then we should be able to run:
This is creating a spring-boot camel project based on the
spring-boot-camel-xml-archetype. This will be used as our base from which to build upon.
Next, we need to add further dependencies to the
<dependencies> section of the
pom.xml file. The following ensures that we have cxf and some groovy goodness.
Add our Static resources
Our WebService WSDL needs to be added to the project so that CXF can generate a service endpoint for it. We add this wsdl to
The following are static responses that will be returned to the client:
Write the code
We will just modify the traditional camel context at
src/main/resources/spring/camel-context.xml to have the following:
- A CXF Service Endpoint
- A Simple route which:
- Exposes the CXF Service with MESSAGE dataFormat
- Generates a random number between 1 and 5 using the Camel Simple Language
- Sets the Body with groovy to read in the full file resource.
Not much code!
Run the Code - Locally
mvn clean spring-boot:run will run the project locally. Open a browser and navigate to
http://localhost:8080/services/ to see the cxf service endpoints:
Run the Code - In the Environment!
Login to minishift, or your openshift cluster and perform the following (my project is named camel-webservice-mocks):
You should now see output from the standard cxf page. And if you navigate in your browser, you should see the endpoint served up via the Openshift cluster/minishift.
