Demonstration of a SOAP to REST Proxy for an existing SOAP service, using Fuse Integration Services 2.0. A video walkthrough demonstrating this project can be found here.
This project demonstrates a microservices based project leveraging SpringBoot and Apache Camel to proxy an existing SOAP service with a new REST front-end service. Additionally, the REST API is documented using Swagger. The project makes use of camel-servlet component listening on port 8080 and configured using Spring Boot.
An OpenShift environment must be present for deployment to to a cloud environment. For the purpose of testing, I prefer to use Minishift
This project can be deployed using two methods:
- Standalone Spring-Boot container
- On an Openshift environment using Fuse Integration Services 2.0
The standalone method takes advantage of the Camel Spring Boot Plugin to build and run the microservice.
Execute the following command from the root project directory:
mvn spring-boot:run -Dspring.profiles.active=dev
Once the spring boot service has started, you can test the REST API by executing the following command
curl http://localhost:8080/api/citiesByCountry/Germany
A list of German weather stations is returned in JSON format. Try other countries as needed.
Additionally, you can reach the REST API using the web browser by navigating to http://localhost:8080/api/citiesByCountry/Germany . It's also possible to navigate the REST service using the Swagger documentation here.
First, create a new OpenShift project called fis-soap-rest-proxy
oc new-project fis-soap-rest-proxy --description="Fuse Integration Services SOAP to REST Proxy Demo" --display-name="SOAP REST Proxy"
Execute the following command which will execute the ocp profile that executes the clean fabric8:deploy maven goal:
mvn -P ocp
The fabric8 maven plugin will perform the following actions:
- Compiles and packages the Java artifact
- Creates the OpenShift API objects
- Starts a Source to Image (S2I) binary build using the previously packaged artifact
- Deploys the application using binary streams
A Swagger User Interface is available within the rest-soap-transformation application to view and invoke the available services.
Select the hyperlink for the gateway application to launch the Swagger UI
The raw swagger definition can also be found at the context path api/api-doc
Using a command line, execute the following to query the definition service
curl -s http://$(oc get routes rest-soap-transformation --template='{{ .spec.host }}')/api/citiesByCountry/Australia | python -m json.tool
A successful response will output the following
