Using a URI Template

If include some properties of the object in the URI, you can use a URI template.

For example imagine you have a Book class with a title property. You can include the title in the URI template and then populate it from an instance of Book. For example:

Sending a JSON body with a URI template

        Flux<HttpResponse<Book>> call = Flux.from(client.exchange(
                POST("/amazon/book/{title}", new Book("The Stand")),
                Book.class
        ));

Sending a JSON body with a URI template

        Flux<HttpResponse<Book>> call = client.exchange(
                POST("/amazon/book/{title}", new Book("The Stand")),
                Book
        );

Sending a JSON body with a URI template

            val call = client.exchange(
                    POST("/amazon/book/{title}", Book("The Stand")),
                    Book::class.java
            )

In the above case the title property is included in the URI.
