spring-way handle slash in resource name

Question

I have following method in controller:

 @RequestMapping(value = "/items/{identifier}", method = RequestMethod.DELETE)
    public void delete(@PathVariable String identifier) {
    ... 
    // find item in database by identifier
}

The problem is identifier is a String that can contain slash ('/'). I.e. situation can occurs:

http://myhost/items/file:/123

For given URL 'identifier' must be "file:/123".

And if there is a '/', 405 (method is not allowed) throws due to incorrect URL.

How to tell Spring that it should take all after '/items/' as 'identifier' (resource name in REST terms)?

EDIT: I was told that it is client's responsibility to manage slashes and encoding, so I left it as it was.

But for the info, based on ankur-singhal answer in comments:

Support that I wanted to was added in Spring 4.1.0, see this link and this commit. So in my case it'll be:

 @RequestMapping(value = "/items/{/identifier}", method = RequestMethod.DELETE)

'/' before 'identifier' did a trick.

I am testing with JUnit so far, not on real application server. — fasth, Sep 11 '14 at 08:20
Just a remark : `/` is said *slash*, and `\ ` is said *backslash* ... — Serge Ballesta, Sep 11 '14 at 08:42

Try changing code to below, see if it works

It will accept any value for identifier.

 @RequestMapping(value = "/items/{identifier:.*}", method = RequestMethod.DELETE)
    public void delete(@PathVariable String identifier) {
    ... 
    // find item in database by identifier
}

If you use identifier as request parameter then you can achieve it as follows :

 @RequestMapping(value = "/items", method = RequestMethod.DELETE)
    public void delete(@RequestParam("identifier") String identifier) {
    ... 
    // find item in database by identifier
}

Please refer here for more info.

It doesn't work. I have tried this. This solution works with dots, for example, but not with backslashes. – fasth Sep 11 '14 at 08:33
@user2138356 using `requestParam`..?? – Ankur Singhal Sep 11 '14 at 08:35
I use {identifier} like resource name not as requestParam. – fasth Sep 11 '14 at 08:38

@user2138356 here is a [link](https://jira.spring.io/browse/SPR-11401), and they talk about encoding the url. – Ankur Singhal Sep 11 '14 at 08:39
