Spring request mapping wildcard exceptions

Question

Can I put /** wildcard in a middle of request mapping such as: "/some/resource/**/somthing"

In Spring 3 I can do this

@RequestMapping("/some/resource/**")

to map

/some/resource/A  -> ControllerMethod1
/some/resource/A/B -> ControllerMethod1
/some/resource/A/B/C/D/E/F -> ControllerMethod1

for any number of paths parts

However this mapping is too greedy and will not allow me to map a sub URL @RequestMapping("/some/resource/**/somthing") to another controller such as

/some/resource/A/somthing  -> ControllerMethod2
/some/resource/A/B/somthing -> ControllerMethod2
/some/resource/A/B/C/D/E/F/somthing -> ControllerMethod2

How can i do this?

I thinks it's not possible to use that ant style in url mapping as you require, because it will stop on the next path separator character '/'.

I would suggest you to try 16.3.2.2. URI Template Patterns with Regular Expressions in order to map just the last part of the request (haven't tried this approach yet).

Also you can match the rest of the request using PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE, and apply some expression there. Check this post.

Otherwise you should use request parameters to match that condition 16.3.2.6. Request Parameters and Header Values.

You can narrow request matching through request parameter conditions such as "myParam", "!myParam", or "myParam=myValue". The first two test for request parameter presense/absence and the third for a specific parameter value. Here is an example with a request parameter value condition.

In this case you will map something like that using params

@RequestMapping(value = {"/some/resource/**"},  params="somthing")

or use the annotation request parameter with not required attribute in method signature:

public void test(@RequestParam(value = "somthing", required=false) String str) {
