[SOLVED] Identifying UriBuilder implementation used by Spring WebClient

Identifying UriBuilder implementation used by Spring WebClient

I use the below syntax to make a get call using get client. In the below example , which implementation of URIBuilder is being used and how is automatically inferenced?

webclient.get().uri(uriBuilder -> uriBuilder.path("/api/person/{personId}")
    .queryParam("param1", aDouble)
    .queryParam("param2", "A string value with spaces")
    .queryParam("param3", aListOfValues)
    .queryParam("param4", null)
    .build(anInteger))

This is the webclient that I am using - WebClient

Solution

You can decide which implementation is used WebClient by providing a UriBuilderFactory while building it.

The WebClient.Builder has a uriBuilderFactory(UriBuilderFactory) method where you can provide your implementation.

If you don't provide one, it currently uses DefaultUriBuilderFactory which produces UriComponentsBuilder instances.

_{You could always instrument your code to print uriBuilder.getClass() for confirmation.}
