Portlet Provider

Dynamically provides portlets to Liferay’s Add Panel (e.g., based on permissions/context).

• Show/hide portlets conditionally (e.g., “Sales Dashboard” only for sales team).
• Lazy-load portlets to improve performance.

Implementation

Create the Module

blade create -t portlet-provider sales-dashboard-provider

Implement Conditional Logic

sales-dashboard-provider/src/main/java/com/example/sales/provider/SalesPortletProvider.java

@Component(
    property = "javax.portlet.name=" + SalesPortletKeys.SALES_DASHBOARD,
    service = PortletProvider.class
)
public class SalesPortletProvider implements PortletProvider {
    @Override
    public Portlet provide() {
        return new SalesDashboardPortlet();
    }

    @Override
    public boolean isAvailable(HttpServletRequest request) {
        // Only show to users with "Sales" role
        return UserUtils.hasRole(request, "Sales");
    }
}

Use Cases

• Role-Based Portlets: HR tools for HR, finance tools for accountants.
• Contextual Portlets: Show “Project Tasks” only in project sites.
