Swagger, Endpoints and Pathparameters - web-services

Question

TLDR: Multiple Pathparameters and Endpoints with Swagger
What i would like to to is some API Endpoint like this:
/foo/{id}/bar
Now afaik foo or the first node in the path is defining the endpoint and also the resource to aqcuire. Therefore a FooApiServiceImpl is generated.
The generated ProjectsApiService stub looks like this atm:
#GET
#Path("/{id}/bars")
...
public Response getBarsByFooId(#ApiParam(value = "The id of the foo with the bars",required=true ) #PathParam("id") String id)
throws NotFoundException {
return delegate.getBarByFooId(id);
}
Now my wished behaviour would be to GET all the Bar resources that are connectted to the Foo with the given {id}. Kinda like the reverse order. Is this somehow possible?
If this is not possible... then would also like to ask, how can i get url nodes (foo, bar) that are not defined as {xxx} paramaters in brackets?
Something like this:
public Response getBarsByFooId(String foo, String id, String bar)
throws NotFoundException {
return delegate.getBarByFooId(id);
}

To get the paths segments, inject a UriInfo in your resource class or method:
#Context
private UriInfo uriInfo;
And then invoke UriInfo.getPathSegments() from it:
List<PathSegment> segments = uriInfo.getPathSegments();
See the UriInfo.getPathSegments() documentation:
Get the path of the current request relative to the base URI as a list of PathSegment. This method is useful when the path needs to be parsed, particularly when matrix parameters may be present in the path. All sequences of escaped octets in path segments and matrix parameter values are decoded, equivalent to getPathSegments(true).
