spring 3 RequestMapping get path value

Question

Is there a way to get the complete path value after the requestMapping pathvariable values has been parsed.

That is: /{id}/{restOfTheUrl} should be able to parse /1/dir1/dir2/file.html id=1 and restOfTheUrl=/dir1/dir2/file.html

Any ideas would be appreciated.

Answer 1

Non-matched part of the URL is exposed as a request attribute named HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE:

@RequestMapping("/{id}/**")
public void foo(@PathVariable("id") int id, HttpServletRequest request) {
    String restOfTheUrl = (String) request.getAttribute(
        HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    ...
}

I have used the Tuckey URLRewriteFilter to handle path elements that contain '/' characters, as I don't think Spring 3 MVC supports them yet.

http://www.tuckey.org/

You put this filter in to your app, and provide an ML config file. In that file you provide rewrite rules, which you can use to translate path elements containing '/' characters into request parameters that Spring MVC can deal with properly using @RequestParam.

WEB-INF/web.xml:

<filter>
  <filter-name>UrlRewriteFilter</filter-name>
  <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<!-- map to /* -->

WEB-INF/urlrewrite.xml:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite
    PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN"
    "http://tuckey.org/res/dtds/urlrewrite3.0.dtd"&gt;
<urlrewrite>
  <rule>
    <from>^/(.*)/(.*)$</from>
    <to last="true">/$1?restOfTheUrl=$2</to>
</urlrewrite>

Controller method:

@RequestMapping("/{id}")
public void handler(@PathVariable("id") int id, @RequestParam("restOfTheUrl") String pathToFile) {
  ...
}
