SEO Friendly URL in Struts 2

A SEO friendly URL supplies request parameters as a part of the URI. Such as /edit-game/zombi-2014 rather than /edit-game?gameId=zombi-2014. This is because Google does not index any text that comes after “?”.

By default, Struts 2 has SEO friendly URL disabled. But, this can be enabled rather easily. In this tutorial, I will show you how to do that in an application using the convention plugin and annotation.

Enable Parameter in URI

Open your struts.xml and add these constants:

<?xml version="1.0" encoding="UTF-8" ?>
 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
 <constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
 <constant name="struts.enable.SlashesInActionNames" value="true"/>
 <constant name="struts.patternMatcher" value="namedVariable"/>

Save changes.

Develop the Action Class

In your action class, define a property where the parameter will be saved. For example, gameId below.

public class GameAction {
 private String gameId;
 //getGameId, setGameId etc.

Next, for an action handler method, specify the property name in the action URI.

public String editGame() {
 System.out.println("Game ID is: " + gameId);
 return "form";

That’s it. Now, you can use the URI /edit-game/zombi-2014 to execute the action handler method.
