A quickstart project that processes users in the system. It's main purpose is to to call external REST service to load a given user by its username.
This example shows
invoking remote REST service
control flow based on service calls

You will need:
mvn clean compile spring-boot:run
mvn clean package
To run the generated native executable, generated in target/
, execute
java -jar target/process-service-rest-call-springboot.jar
You can take a look at the OpenAPI definition - automatically generated and included in this service - to determine all available operations exposed by this service. For easy readability you can visualize the OpenAPI definition file using a UI tool like for example available Swagger UI.
In addition, various clients to interact with this service can be easily generated using this OpenAPI definition.
To make use of this application it is as simple as putting a sending request to http://localhost:8080/users
with following content
{ "username" : "test" }
Complete curl command can be found below:
curl -X POST -H 'Content-Type:application/json' -H 'Accept:application/json' -d '{"username" : "test"}' http://localhost:8080/users
After the above command you should see some log on Springboot sush as following
To test the other route possible for unknown user send request to http://localhost:8080/users
with following content
{ "username" : "nonexisting" }
Complete curl command can be found below:
curl -X POST -H 'Content-Type:application/json' -H 'Accept:application/json' -d '{"username" : "nonexisting"}' http://localhost:8080/users
After the above command nothing will show on Springboot log as the user is skipped but you should see the following on terminal after curl
In the operator
directory you'll find the custom resources needed to deploy this example on OpenShift with the Kogito Operator.
