Spring Boot 3.3 已弃用 HttpComponentsClientHttpRequestFactory

Question

我有一个代码如下：

RestTemplate restTemplate = new RestTemplate();
TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
CloseableHttpClient closableHttpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient((HttpClient) closableHttpClient);
restTemplate = new RestTemplate(requestFactory);

在上面的代码中，我试图跳过 SSL 验证。

问题：从Spring Boot版本2.7升级到3.3并从Apachehttpclient4升级到httpclient5时，显示

HttpComponentsClientHttpRequestFactory

已被弃用。

如何解决这个问题？

Answer 1

HttpComponentsClientHttpRequestFactory

在 Spring Boot 3.3 中并未弃用。

阅读 Java 文档这里。

我已更新您的代码以修复与 httpclient5 的兼容性问题。

RestTemplate restTemplate = new RestTemplate();
TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
HttpClientConnectionManager connectionManager = PoolingHttpClientConnectionManagerBuilder.create().setSSLSocketFactory(csf).build();
CloseableHttpClient closableHttpClient = HttpClients.custom().setConnectionManager(connectionManager).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(closableHttpClient);
restTemplate = new RestTemplate(requestFactory);

看看这是否有帮助。
