By default the regular expression for a path parameter is [^/]+, i.e.
any but a /, which means a path segment.
You can express your own regular expression for a path parameter by
declaring the expression in the @Path:
@Path("{segments: .+")
The above means one or more of any character, and thus consumes the
rest of the URI path that was not previously matched.
If you want to match something like you are doing above you can use
the following:
@Path("{id: \\w+/\\w+}")
