Create MVC Portlet in Liferay 7 using LiferayIDE

Liferay 7 has adopted OSGI standards.In OSGI everything we create is a module.For more information on OSGI visit my previous blog onOSGI.

Create MVC Module using Liferay IDE.

GoTo New→File click on Liferay Module Project.

• Enter Project Name and select mvcportlet as project template.
• Click Next and enter component class name and package name then click on finished.

Generated module will be inside module folder of liferay workspace.

Generated Portlet Class

• Based on input provided generated portlet class is 

ProductRegistrationPortlet.java

package com.liferay.product.portlet;

import com.liferay.portal.kernel.portlet.bridges.mvc.MVCPortlet;

import javax.portlet.Portlet;

import org.osgi.service.component.annotations.Component;

@Component(

immediate = true,

property = {

"com.liferay.portlet.display-category=category.sample",

"com.liferay.portlet.instanceable=true",

"javax.portlet.display-name=ProductRegistration Portlet",

"javax.portlet.init-param.template-path=/",

"javax.portlet.init-param.view-template=/view.jsp",

"javax.portlet.resource-bundle=content.Language",

"javax.portlet.security-role-ref=power-user,user"

},

service = Portlet.class

)

public class ProductRegistrationPortlet extends MVCPortlet {

}

• Here property{

          

         }

tag is used to specify properties that are previously specified in portlet.xml and  liferay-portlet.xml

• For more detail on mapping of portlet XML descriptor values to OSGi service properties click here.
• Now we can have to build and deploy generated mvc portlet using gradle tasks as shown in fig.

• Click on build this will generate jar file of porltet module.On clicking deploy this jar will be deployed and your portlet will be available.
• Note you must have to set liferay.workspace.home.dirand liferay.workspace.modules.default.repository.enabled     properties in gradle.properties (for more information click here)
