Invoicing

The workflow and its implementation are described here.

The InvoicingWorkflow(Java, Kotlin) implements a simple process to prepare and send an invoice to a user every month. It includes:

Deployment

To be able to run InvoicingWorkflow instances:

  • Run a few MetricsService workers

    • in Java (config): ./gradlew service-metrics:run-java
    • and/or in Kotlin (config): ./gradlew service-metrics:run-kotlin

  • Run a few InvoiceService workers

    • in Java (config): ./gradlew service-invoice:run-java
    • and/or in Kotlin (config): ./gradlew service-invoice:run-kotlin

  • Run a few NotificationService workers

    • in Java (config): ./gradlew service-notification:run-java
    • and/or in Kotlin (config): ./gradlew service-notification:run-kotlin

  • Run a few InvoicingWorkflow workers

    • in Java (config): ./gradlew workflow-invoicing:run-java
    • and/or in Kotlin (config): ./gradlew workflow-invoicing:run-kotlin

  • Run a few PaymentWorkflow workers

    • in Java (config): ./gradlew workflow-payment:run-java
    • and/or in Kotlin (config): ./gradlew workflow-payment:run-kotlin

Starting Instances

To start (code) 3 InvoicingWorkflow instances, run: ./gradlew common:invoicing-start --args '3'.

The consoles should look like (Notes: for convenience, in the examples the invoices are generated every minute instead of every day):
