Helidon WebClient typed collections serialization/deserialization examples

[RassulYunussov]

In essence I would like to obtain the same scenario as we have for a single element but with typed collections.

If we have something like this for a single element

WebClient webClient = WebClient.builder()
            .baseUri("http://localhost:8084")
            .build();

Product product = webClient.get()
                            .path("/product")
                            .requestEntity(Product.class);

How should it be for List?

Considering usage of helidon-http-media-jackson

(Disclaimer: I confess that the fluent style of APIs is never obvious to me; I'm an old-school javadoc-first person.)

Working backwards, you want a GenericType, I think. Its documentation is very difficult to understand, but I think you create one like this (note the anonymous subclass nature of it):

new GenericType<List<Product>>() {};

So, untested, but does:

webClient.get()
    .path("/product")
    .request()
    .entity()
    .as(new GenericType<List<Product>>() {});

…get you pointed in the right direction? Or am I way off?

That works, thank you!
