Passing parameters in URL without query string in Struts 2 (2 answers)

Closed 6 years ago.

I have a package name

/cabinet/s

where all actions return JSP snippets.

and the rest of the path of any URL for this package below

/cabinet/s/actionid/snippetgroup/filename.do

• actionid - identifier for action class
• snippetgroup - identifier of snippets group for certain functionality (this is just a directory name)
• filename - JSP filename

<action name="actionid/*/*" class="someclass">
   <result>/WEB-INF/jsp/{1}/{2}.jps</result>
</action>

The problem is that Struts never call a correct class. It always errors that filename action does not exist.

Struts application is configured to use .do extension instead of .action.

Answer 1

You must set this options in struts.xml according to the documentation:

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

and probably remove the .do extension, by setting it to empty (or better to comma, to prevent Struts handling static resources as namespaces):

<constant name="struts.action.extension" value=","/>

Otherwise, you can switch to Advanced Wildcards by using regex Pattern Matcher.

Answer 2

In order this to work you need to set struts.enable.SlashesInActionNames to true and struts.mapper.alwaysSelectFullNamespace to false in your configuration.

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

And you probably need to change your result to:

<result>/WEB-INF/jsp/{1}/{2}.jsp</result>

Also have you configured Struts2 to use .do as action extension or not? If no then you need to remove it from the url.

Answer 3

The problem is that you use relative path to the package specified. But you should use an absolute pathname.

<action name="actionid/*/*" class="someclass"> 
   <param name="snipetgroup">{1}</param>
   <param name="filename">{2}</param>
   <result>/WEB-INF/jsp/${snipetgroup}/${filename}.jsp</result> 
</action>

This technique is called Parameters after the action name. Note, this feature is available since Struts 2.2.1. Once applied you can use dynamic parameters in result.
