java - requestFactory(Class<? extends ClientHttpRequestFactory>) 类型 RestTemplateBuilder 不适用

Question

我在我的项目中使用 springBootVersion = '2.0.1.RELEASE'。我正在尝试为我编写的 RestClientCertTestConfiguration 类编写相互身份验证代码，如下所示。我在 requestFactory 上收到错误。 RestTemplateBuilder 类型中的方法 requestFactory(Class) 不适用于参数 (HttpComponentsClientHttpRequestFactory) 关于如何解决此问题的任何建议？谢谢

    @Configuration
public class RestClientCertTestConfiguration {

    private String allPassword = "mypassword";

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) throws Exception {

        SSLContext sslContext = SSLContextBuilder
                .create()
                .loadKeyMaterial(ResourceUtils.getFile("classpath:myCerts.jks"), allPassword.toCharArray(), allPassword.toCharArray())
                .loadTrustMaterial(ResourceUtils.getFile("classpath:myCerts.jks"), allPassword.toCharArray())
                .build();

        HttpClient client = HttpClients.custom()
                .setSSLContext(sslContext)
                .build();

        return builder 
                 //error on this line
                .requestFactory(new HttpComponentsClientHttpRequestFactory(client))
                .build();
    }

}

requestFactory方法采用类或 Supplier<ClientHttpRequestFactory>所以你需要做:

.requestFactory(HttpComponentsClientHttpRequestFactory.class)

或

.requestFactory(() -> new HttpComponentsClientHttpRequestFactory(client))

大概是后者，因为你想传入 client .
