Hospital Example
This example combines Rio and Drools Fusion through the use of the Gnostic service. This example demonstrates the use of associations, association based dependency injection, watches, and the incorporation of rules to manage SLA behavior.
You interact with a user interface to admit patients to the hospital. You can admit them one by one, or several at a time. The Hospital has a rule (DoctorRule.drl) that when a Doctor has more than 3 patients, an ON CALL Doctor is changed to ON DUTY.
If the number of patients being admitted exceeds the amount of available beds, beds are dynamically scaled (each Bed is a dynamic service) to meet the needs of the Hospital. The rule that scales beds is found in AvailableBedRule.drl.
Check out how to use the user interface provided with the example.
Building the example
The Hospital example is a multi-module Maven project, with the following structure (just inter-project dependencies are shown):
The example produces the following artifacts:
| Artifact | Description |
| hospital-service-2.0.jar | Artifact containing service implementation classes |
| hospital-rule-2.0.jar | Artifact containing service rules resources |
| hospital-api-2.0.jar | Artifact that contains classes required for a client to invoke methods on the hospital services |
| hospital-ui-2.0.jar | Artifact that contains classes required for a user interface to the hospital |
| hospital-2.0.oar | The OperationalString archive, contains the configuration artifacts used to deploy the hospital application |
Running mvn install will result in the execution of integration tests that use the Rio test infrastructure
