Liferay provides working examples of sample projects that target different integration points in Liferay DXP. These working examples can be copy/pasted into your own independent project so you can take advantage of various Liferay extension points. Each sample is a standalone project and includes its own build files. Liferay’s sample projects can be found in the liferay-blade-samples repository on GitHub. You can find documentation for Liferay’s sample projects in the Sample Projects reference section.
You can also use Blade CLI to create samples by running this command:
blade samples [SAMPLE_NAME]
For example, the following command generates the ds-portlet sample:
blade samples ds-portlet
At first glance, you’ll notice that the repository is broken up into three primary folders:
The provided sample projects are organized by their development toolchains to
cater to a variety of developers. Each folder offers the same set of sample
Liferay projects. Their only difference is that the build files are specific to
their toolchain. For example, the
gradle folder contains projects using
standard OSS Gradle plugins that can be added to any Gradle composite build. The
same concept also applies to the
gradle folder also uses the Liferay Gradle plugin (e.g.,
com.liferay.plugin) which encompasses additional functionality for various
types of Liferay projects. The Liferay Gradle plugin is recommended for Gradle
users developing for Liferay DXP.
Some samples also come configured with logging to help you fully understand what the sample is accomplishing behind the scenes. For example, OSGi module logging is implemented for several samples (e.g., action-command-portlet, document-action, service-builder/jdbc, etc.), which lets OSGi modules supply their own logging configuration defaults without external configuration. See the Adjusting Module Logging tutorial for more information.
For a list of sample template projects available, visit the Liferay extension points sub-section in the Liferay Blade Samples repository. This list is not comprehensive. A subset of missing extension point samples can be found in the Liferay extension points without template projects sub-section.
