Bootstrap Liferay Advanced Developer Environments (BLADE)

Build Status Join the chat at https://gitter.im/rotty3000/blade

Liferay's Blade samples provides bootstrap project environments for all major build tools in common use for Java projects so that Liferay development can start quickly and easily.

Build Tools

The template projects are categorized under four build tools:

  • liferay-gradle - A set of Liferay projects that can be bootstrapped onto the com.liferay.plugin (a Gradle plugin) based development environment.
  • maven - A set of Liferay projects that can be bootstrapped onto the Maven development environment.

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.

login.events.pre

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.

Template project description: Demonstrates a hook for login.events.pre.

Template projects links:

Build tool Link to project's source code
Liferay Gradle ./liferay-gradle/blade.lifecycle.loginpreaction
Maven ./maven/blade.lifecycle.loginpreaction

ModelListener

Extension point description: Model Listeners are used to listen for events on models and do something in response.

Template project description: Demonstrates how to create a model listener for Layout.

After deploying this plugin, the title of any newly created page will be automatically set to Title generated by model listener!.

PollerProcessor

Extension point description:

Template project description: Demonstrates how to make a hook for a PollerProcessor.

Template projects links:

Build tool Link to project's source code
Liferay Gradle ./liferay-gradle/blade.pollprocessor
Maven ./maven/blade.pollprocessor

MVCActionCommand

Extension point description:

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).

REST Service

Extension point description: Lets developers create custom JAX-RS standard based RESTful services.

Template project description: Demonstrates how to create a JAX-RS service that lists Liferay users.

NOTE: Before this service is accessible, the developer needs to configure endpoints for it. To do so, go to the Control Panel → System → System Settings → Foundation and then

  • Search for CXF Endpoints
  • Create a new CXFEndpoint publisher configuration providing a context path (e.g., /rest-test).
  • Go back to System Settings → Foundation and select REST Extender.
  • Create a new REST extender configuration (i.e., search with rest) providing context paths (e.g., /rest-test) and jaxrs.applications.filters set to (jaxrs.application=true).

Then you can access the service via http://localhost:8080/o/rest-test/blade.users/list/.
