This project was generated using my kie-rules-archetype template (maven archetype).
It contains two decision/rules artifacts.
-
a Car Insurance Policy Pricing Decision Table implemented using Drools XLS Spreadsheet.
-
a Traffic Violation Decision implemented using DMN.
It also contains unit tests for both Drools and DMN rules and visual tabular Test Scenario Simulation. Execute the tests with mvn test to see the results.
To build and install the kjar in your local maven repository (~/.m2/repository)
mvn clean install -DskipTests
Take a look at the business-application-service instructions to see how you can deploy and run your kjar using the Immutable Kie Server Spring Boot runtime in your local environment.
after building and deploying your kjar into a kie-server you can test the API using the following payload samples:
if running on Spring Boot use this url: http://localhost:8090/rest/server/server/containers/decisions-showcase-1.0.0-SNAPSHOT/dmn
copy the model-namespace and the model-name
