Subject [jira] [Commented] (WW-3262) improve wildcard to support regular expressions
Date Thu, 07 Jan 2016 17:12:39 GMT


victorsosa commented on WW-3262:

Base on the JSR-339

Template parameters can optionally specify the regular expression used to match their values.
 The default value matches any text and terminates at the end of a path segment but other
values can be used to alter this behavior, e.g.:


public class Widget {



In the above example the Widgetresource class will be matched for any request whose path starts
widgets and contains at least one more path segment; the value of the path parameter will
be the request
path following widgets.   E.g.   given the request path widgets/small/a the value of path
would be small/a.

Shouldn't this b implemented as part of the REST plugin???

> The regular expressions will follow the syntax of JAX-RS. They can be like {PARAM_NAME}
or {PARAM_NAME:REGEX}. For example:
>        <package name="regex" extends="struts-default" namespace="/">
> 		<action name="/{bio:.+}/test/{name}" class="org.apache.struts2.showcase.UITagExample">
> 			<result>/tags/ui/example.jsp</result>
> 		</action>
> 	</package>
> 	<package name="regex2" extends="struts-default" namespace="/superurl">
> 		<action name="/{bio:.+}/test/{name}" class="org.apache.struts2.showcase.UITagExample">
> 			<result>/tags/ui/example.jsp</result>
> 		</action>
> 		<action name="/{bio:.+}/test2/{name}" class="org.apache.struts2.showcase.UITagExample">
> 			<result>/tags/ui/{1}.jsp</result>
> 		</action>
> 	</package>
