Clientbuilder.sslsocketfactory(sslsocketfactory) not supported on jdk 9+

When using the ClientBuilder class in JDK 9 and above, the method sslSocketFactory() is not supported directly. This method allowed you to set a custom SSL socket factory for making HTTPS connections.

Instead, starting from JDK 9, the preferred way to configure SSL/TLS settings for HTTP clients is through the HttpClient class introduced in the java.net.http package. The HttpClient class provides a more modern and flexible API for making HTTP requests.

Here is an example on how to configure SSL/TLS settings using the HttpClient class in JDK 9+:

    
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLParameters;

// Create a custom SSLContext with desired SSL/TLS configuration
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, null, null);

// Create custom SSLParameters
SSLParameters sslParameters = new SSLParameters();
sslParameters.setProtocols(new String[] { "TLSv1.2" }); // Set desired protocols

// Create HttpClient with desired SSL/TLS settings
HttpClient httpClient = HttpClient.newBuilder()
        .sslContext(sslContext)
        .sslParameters(sslParameters)
        .build();

// Create HttpRequest and send the request
HttpRequest request = HttpRequest.newBuilder()
        .uri(new URI("https://example.com"))
        .build();
        
HttpResponse response = httpClient.send(request, HttpResponse.BodyHandlers.ofString());

// Process the response
System.out.println(response.body());
    
  

In this example, we first create a custom SSLContext and SSLParameters with the desired SSL/TLS configuration. Then, we use the HttpClient.newBuilder() method to create a new HttpClient instance, and use the sslContext() and sslParameters() methods to set the custom SSLContext and SSLParameters respectively. Finally, we make an HTTP request and process the response.
