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.
  • 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.
  • 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 three 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 three 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).
