How to create Friendly URL for Liferay portlet

• Q-What is friendly URL?
• ans: Friendly URL is a technique to make short portlet URL.
• To make friendly URL, we need to define router xml for that portlet.
• In this router xml, we can define various parameters (implicit , explicit etc).
• We can define multiple friendly URL for same portlet.

 Step1--first we need to create friendly-url-router.xml  inside src.
example:-
<?xml version="1.0"?>
<!DOCTYPE routes PUBLIC "-//Liferay//DTD Friendly URL Routes 6.2.0//EN"
"http://www.liferay.com/dtd/liferay-friendly-url-routes_6_2_0.dtd">

<routes>
    <route>
        <pattern>/{jspPageName}</pattern>
        <generated-parameter name="jspPage">/html/controller/{jspPageName}.jsp</generated-parameter>
        <implicit-parameter name="p_p_lifecycle">0</implicit-parameter>
        <implicit-parameter name="p_p_state">normal</implicit-parameter>
        <implicit-parameter name="p_p_mode">view</implicit-parameter>
    </route>
</routes>

Step2- we need to add three line code in liferay-portlet.xml

<icon>/icon.png</icon><friendly-url-mapper-class>com.liferay.portal.kernel.portlet.DefaultFriendlyURLMapper</friendly-url-mapper-class><friendly-url-mapping>ekhub</friendly-url-mapping><friendly-url-routes>com/test/ccavenue-friendly-url-routes.xml</friendly-url-routes><instanceable>false</instanceable>
