Sample Projects for Liferay Portal

Liferay's sample projects provides bootstrap project environments for all major build tools in common use for Java projects so that Liferay development can start quickly and easily. These templates can be copied freely and contributions are welcome. See the Contribution Guidelines for more information on how to contribute new sample projects and/or documentation.

Build Tools

The template projects are categorized under two build tools:

  • liferay-workspace - A set of Liferay projects configured to work in a Liferay Workspace environment.
  • liferay-workspace-test-integration-sample - A Liferay project configured to execute Integration Tests.
  • maven - A set of Liferay projects that can be bootstrapped onto the Maven development environment.

Usage

The projects follow the Liferay Workspace project style for gradle and maven.

  • liferay-workspace - in gradle.properties, Set liferay.workspace.product to the target product version.
  • liferay-workspace-test-integration-sample - The test project is in modules/sample/sample-test folder. Run gradlew buildService testIntegration in modules/sample.
  • maven - Set the corresponding release.portal.bom found in dependencyManagement

Contribution Guidelines

When contributing a new sample, you must include accompanying documentation.

Sample Code

You can contribute additional template samples by creating the project for one of the possible build tools and sending a pull request to liferay/liferay-blade-samples. A repository admin will review the submission and replicate the project for the other supported build tools, once the submission is approved.

Sample Docs

You can contribute documentation by adding a README.markdown file to the root folder of a sample project. This article should include the following sections:

  • What does this sample do when it's deployed?
  • What API(s) and/or code components does this sample highlight?
  • How does this sample leverage the API(s) and/or code component?

For example, the Resource Bundle Override article explains the resource-bundle-override sample using the aforementioned sections.

Frameworks

The template projects also demonstrate how to use various frameworks:

  • Blueprint
  • Declarative Services (DS)
  • OSGi API

A Note on Blueprint

Liferay does not provide a Blueprint implementation out of the box. To use the Blueprint modules provided in Blade, you must deploy a Blueprint implementation such as Apache Aries - Blueprint. Three bundles are needed:

Simply download the bundles from mvnrepository and drop them in your osgi/modules folder before deploying Blueprint bundles.

Liferay Extension Points and Template Projects

Apps

Action Command Portlet

Template project description: Demonstrates the MVCActionCommand extension point. It integrates the action command named greet with portlet greeter. To see how this example works, a portlet plugin with a portlet named greeter (javax.portlet.name='greeter') should be deployed. The command adds a key greeting_message to Liferay SessionMessages, along with a session attribute GREETER_MESSAGE. You can independently deploy the bundle blade.portlet.actioncommand (i.e., refresh the bundle without the need to redeploy the Portlet plugin).

Lifecycle Login Pre-action

Extension point description: Demonstrates how to implement a Liferay com.liferay.portal.kernel.events.LifecycleAction. This API replaces all the legacy lifecycle events such as com.liferay.portal.kernel.events.Action, com.liferay.portal.kernel.events.SessionAction, and com.liferay.portal.kernel.events.SimpleAction. Connecting a LifecycleAction to a particular event is determined by the OSGi service property key. The following keys are supported:

  • application.shutdown.events - fired during destruction of company instances at portal shutdown.
  • application.startup.events - fired during initialization of company instances at portal start, or when a new instance is created.
  • global.shutdown.events - fired during destruction of the portal's main servlet.
  • global.startup.events - fire during initialization of the portal's main servlet.
  • layout.configuration.action.delete - fired during destruction of a page (Layout).
  • layout.configuration.action.update - fired during initialization of a page (Layout).
  • login.events.post - fired immediately following login.
  • login.events.pre - fired immediately prior to login.
  • logout.events.post - fired immediately following logout.
  • logout.events.pre - fired immediately prior to logout.
  • servlet.service.events.post - fired following requests to the portal (including all portlet container requests).
  • servlet.service.events.pre - fired prior to requests to the portal (including all portlet container requests & post login).
  • servlet.session.create.events - fired during creation of a portal's HTTP session.
  • servlet.session.destroy.events - fired during destruction of a portal's HTTP session.
