How to create custom URL in Struts 2? Like www.twitter.com/goodyzain

Question

I am working on a project where I want to provide unique URL for each user.

For example:

• www.SocialNetwork.com/jhon
• www.SocialNetwork.com/jasmine

So far I'm able to achieve this:

• www.SocialNetwork.com/profiles/jasmine

here profiles is my action where I can get the user name by

<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.enable.SlashesInActionNames" value="true"/>
<constant name="struts.patternMatcher" value="namedVariable"/> 


<action name="profiles/{username}" class="com.example.actions.ViewProfileAction">
  <result name="input">/WEB-INF/jsp/profile.jsp</result>
</action> 

but I want to achieve something like this:

• www.SocialNetwork.com/jasmine

Just use domain name and username.

Like Twitter does:

• www.twitter.com/username

How to achieve this?

So why do you put profiles/ in front of the action name if you don't want it to be there? – Tiffa

i dont need profiles to be in URL...for users it should be simple...like Domainname/username...simple one.. – Cortico

So remove it from action name. – Tiffa

U mean to tell... SocialNetwork/jasmine but the problem is jasmine is a username...i dont have any action class so that i can process the name and redirect to his profile page... – Cortico

@goodyzian How do you distinguish between user names and and other actions? – Galer

Yeah...that was other case...i will assign them a unique Id...like the username not going to be just Jhon...i will give something like this...Jhon+unique id...like SocialNetwork/jasmine$8383992Juuf, Roman C sir i am just finding a way where i can provide Unique urls to every user...:)in simple fashion like domainname/username..is this achievable.?? – Cortico

Why not if you have only one action in the root namespace that gets the username as a parameter in url? – Galer

like this...<package name="default" extends="struts-default,json-default,jasperreports-default" namespace="profiles"> Or can u tell me How to do this...?? – Cortico

I made a complete sample for the above. If any one wants please refer here – Andaman

@Rajesh its mine...:p :p :p – Cortico

@Cortico I accept. But I made that for the new users to understand completely and easily all discussions made here. – Andaman

Answer 1

If you want to use named patterns in wildcard mapping then you should configure following in the struts.xml:

<constant name="struts.enable.SlashesInActionNames" value="true"/>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.patternMatcher" value="regex"/>

now assume com.example.actions.ViewProfileAction bean has a property username, and method execute that returns a SUCCESS result. Then you can map the action in the root namespace "/" configured to your package.

<action name="{username}" class="com.example.actions.ViewProfileAction">
  <result>/WEB-INF/jsp/profile.jsp</result>
</action>

you can get the name in the JSP using OGNL

<s:property value="username"/>

Also note that you should deploy to the root context to have

your.domain.com/username mapped to your action.

Sorry its working for me, I missed entry in the web.xml :( – Vagina

Answer 2

Try this out. It may work. Use Freemarker USE $.

<action name="profiles/${username}" class="com.example.actions.ViewProfileAction">
    <result name="input">/WEB-INF/jsp/profile.jsp</result>
</action> 

It may work

it will work fine...i want the URL to look like this... SocialNetwork/jasmine Not Like SocialNetwork/profiles/jasmine i dont want to call profiles action...in url – Cortico

So don't use profiles. use only action name="${username}". it will work for you. – Futhark

SocialNetwork is Domain Name,Jasmine is Username...Profiles Is actions name...I dont want user to enter action name which is profiles..i just want them to enter them is Domainname/username NOTE:no action name is called in URL – Cortico

i voted your question up. its a nice question. i will work on it. – Futhark

How to call this action from the login form? I tried like <s:form> <s:textfield name="username"/> <s:submit/> But it is calling just .action like localhost:8080/CustomURL/.action </s:form> – Andaman

@Cortico that i was telling you yesterday. that remove profiles and use ognl like Roman C sir said. you can see my comments also. and set the action file means java file in class attribute of action tag. jsp remains same as it is. – Futhark

@Rajesh here we are using in the Above question <s:form action="{username}"> and struts.xml <action name="{username}">. i think by this you get your answer. – Futhark

@Futhark Thanks. As you mentioned I added but it is not showing the correct url it shows name username in URL. I posted a separate question for that here. Please suggest. – Andaman

@Futhark Yeh..Paresh You told me that in comments...But i was in confused state..before thinking of Ticking Your Answer RomonC sir told He will Work on this and Posted the Full answer...so i voted your Answer :( – Cortico

its okay. i am happy that you got your answer. – Futhark
