get template format string with UrlBuilder

Question

Is there any way to get url template format from URI or UriBuilder? ex) "/{id}?testQuery=test"

when doing this:

uriBuilder
    .path("/{id}")
    .queryParam("testQuery", "test")
    .build(1).toString()

and got "/1?testQuery=test".

I tried .toUriString instead of .build, but it came out as /%7Bid%7D?testQuery=test. Similar to what i want, but not exactly. Does anyone have a solution for this problem?
