java - SpringBoot 2.15 中 RestTemplateBuilder 中的类转换问题

Question

这个问题已经有答案了:

Custom RestTemplate using requestFactory of RestTemplateBuilder in SpringBoot 2.1.x is not backward compatible with version 1.5.x (4 个回答)

已关闭 3 年前。

我的程序中有这段代码:

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

但是我有这个编译错误

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

即使该方法也期望这样:

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

和类(class)HttpComponentsClientHttpRequestFactory implements ClientHttpRequestFactory, DisposableBean

Answer 1

试试这个方法

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