Content Targeting Rule Template

In this article, you’ll learn how to create a Liferay Content Targeting Rule application as a Liferay module. To create a Content Targeting Rule via the command line using Blade CLI or Maven, use one of the commands with the following parameters:

blade create -t content-targeting-rule -p [package name] -c [class name] [project name]

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.content.targeting.rule \
    -DartifactId=[projectName] \
    -Dpackage=[packageName] \
    -DclassName=[className]

The template for this kind of project is content-targeting-rule. To create a rule project called weather with a package prefix of com.liferay and a class name of Weather, use this command:

blade create -t content-targeting-rule -p com.liferay -c Weather weather

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.content.targeting.rule \
    -DgroupId=com.liferay \
    -DartifactId=weather \
    -Dpackage=com.liferay \
    -Dversion=1.0 \
    -DclassName=Weather \
    -Dauthor=Joe Bloggs

The command above creates a Content Targeting Rule project named weather in the current folder. In the class, you’re creating a service of type com.liferay.content.targeting.api.model.Rule and extending the com.liferay.content.targeting.api.model.BaseJSPRule class. Here, service means an OSGi service, not a Liferay API. Another way to say service type is to say component type.

After running the command above, your project’s folder structure looks like this:

• weather
  • gradle (only in Blade CLI generated projects)
    • wrapper
      • gradle-wrapper.jar
      • gradle-wrapper.properties
  • src
    • main
      • java
        • com/liferay/content/targeting/rule
          • WeatherRule.java
      • resources
        • content
          • Language.properties
        • META-INF
          • resources
            • view.jsp
  • bnd.bnd
  • build.gradle
  • [gradlew|pom.xml]

The generated module is a working application and is deployable to a Liferay DXP instance. To build upon the generated app, modify the project by adding logic and additional files to the folders outlined above.
