killbill-email-notifications-plugin

The Kill Bill email notification plugin is a plugin that can be used to send emails when certain events occur. The easiest way to get started with the email notification plugin is to take a look at our Email Notification Plugin Document which provides detailed instructions for installing, configuring and using the plugin.

Requirements

• The plugin requires Kill Bill and Kaui installed. The Getting Started document explains how to set this up.

• In addition, the plugin also needs a database. The latest version of the schema can be found here.

Versions

Release builds are available on Maven Central with coordinates org.kill-bill.billing.plugin.java:killbill-email-notifications-plugin.

mvn clean install -DskipTests=true

Installation

kpm install_java_plugin 'email-notifications' --from-source-file=<jar_file_path> --destination=<path_to_install_plugin>

Custom InvoiceFormatter

A custom InvoiceFormatter implementation can be provided by another Java plugin, by registering a InvoiceFormatterFactory service in the OSGi runtime. This plugin will use the highest-ranking InvoiceFormatterFactory service found. If none are found then a default implementation will be used.

A custom factory can be registered in your plugin's org.osgi.framework.BundleActivator. For example:

import org.killbill.billing.osgi.libs.killbill.KillbillActivatorBase;
import org.killbill.billing.plugin.notification.api.InvoiceFormatterFactory;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceRegistration;

public class Activator extends KillbillActivatorBase {

  private MyCustomInvoiceFormatterFactory factory;
  private ServiceRegistration<InvoiceFormatterFactory> registration = null;

  @Override
  public void start(final BundleContext context) throws Exception {
    super.start(context);

    // create custom factory instance
    factory = new MyCustomInvoiceFormatterFactory();

    // register factory as OSGi service
    Hashtable<String, Object> properties = new Hashtable<>();
    registration = context.registerService(InvoiceFormatterFactory.class, factory, properties);
  }

  @Override
  public void stop(BundleContext context) throws Exception {
    super.stop(context);
    if (registration != null) {
      registration.unregister();
      registration = null;
    }
  }
}

Testing

SMTP Server

In order to test the plugin, the easiest route is to start a local SMTP server. We are typically relying on the namshi/smtp docker image:

Replace `<jar_file_path>` with the path of the email notification plugin jar file and `<path_to_install_plugin>` with the path where you want to install the plugin. This path should match the path specified by the `org.killbill.osgi.bundle.install.dir` property in the Kill Bill configuration file
