How to get pathvariables from a REST URL?

I have the URL path

/customer/7854/order/125

How do I get the customerID 7854 and the orderID 125? Currently I'm handling this by splitting the complete string but I don't like it.

Are there alternatives?

If you using Spring REST, you can use @PathVariable("id") long id. eg for multiple params:

@RequestMapping(value = "/ex/foos/{fooid}/bar/{barid}")
@ResponseBody
public String getPathValues
  (@PathVariable long fooid, @PathVariable long barid) {
    return "Get a specific Bar with id=" + barid + " from a Foo with id=" + fooid;
}

As you said in the comments, you're using Spring MVC.

Luckily for you, it provides a really nice way of mapping URL parameters to values!

@RequestMapping(value = "/{bookmarkId}", method = RequestMethod.GET)

As you can see, on the action, you can specify the bookmarkId. And then you specify the parameter..

Bookmark readBookmark(@PathVariable Long bookmarkId)

And now you can access bookmarkId as if it was any other value.

Edit

So the whole thing together, taken from the examples, would look like this:

@RequestMapping(value = "/{bookmarkId}", method = RequestMethod.GET)
Bookmark readBookmark(@PathVariable String userId, @PathVariable Long bookmarkId) {
    this.validateUser(userId);
    return this.bookmarkRepository.findOne(bookmarkId);
}
