I have a code given below:
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);
In the above code, I am trying to skip the SSL validation.
Issue: When upgrading from Spring Boot version 2.7 to 3.3, according to docs for migrating from Apache httpclient4 to httpclient5, it’s mentioned that HttpComponentsClientHttpRequestFactory got deprecated.
How to resolve this issue?

HttpComponentsClientHttpRequestFactory is not deprecated in Spring Boot 3.3.
Read the Java Docs here.
I have updated your code to fix the compatibility issue with httpclient5.
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);
See if this helps.
