class Cast problem in RestTemplateBuilder with SpringBoot 2.15

Question

I have this piece of code in my program:

this.restTemplate = restTemplateBuilder
                .requestFactory(new HttpComponentsClientHttpRequestFactory());

but I have this compilation error

Cannot resolve method 'requestFactory(org.springframework.http.client.HttpComponentsClientHttpRequestFactory)'

Even the method expects this:

 public RestTemplateBuilder requestFactory(Class<? extends ClientHttpRequestFactory> requestFactory)

and the class HttpComponentsClientHttpRequestFactory implements ClientHttpRequestFactory, DisposableBean

The parameter is expected to be the `Class` object of the factory. Not the instance of the factory as you're trying to pass in. — Kayaman, May 22 '20 at 09:15

Try this way

HttpClientBuilder clientBuilder = HttpClientBuilder.create();
HttpClient httpClient = clientBuilder.build();
restTemplatebuilder.requestFactory(() -> { return new HttpComponentsClientHttpRequestFactory(httpClient);});
