Explanation of clientbuilder.sslsocketfactory(sslsocketfactory) in JDK 9+
Starting from JDK 9, the method clientbuilder.sslsocketfactory(sslsocketfactory)
is not supported anymore. This method was used in previous versions of JDK to set a custom SSL socket factory for the HTTP client builder. An SSL socket factory provides the ability to create SSL sockets for secure communication over HTTPS.
In JDK 9 and later versions, the HttpClient
class was introduced as a replacement for the deprecated HttpURLConnection
class. The HttpClient
class provides more flexible and modern APIs for making HTTP requests and handling responses.
Example: Using HttpClient in JDK 11+
import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
public class ExampleHttpClient {
public static void main(String[] args) {
HttpClient httpClient = HttpClient.newBuilder()
.build();
HttpRequest httpRequest = HttpRequest.newBuilder()
.uri(URI.create("https://example.com"))
.build();
try {
HttpResponse response = httpClient.send(httpRequest, HttpResponse.BodyHandlers.ofString());
System.out.println("Response code: " + response.statusCode());
System.out.println("Response body: " + response.body());
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}
}
}
The example code demonstrates how to use the new HttpClient
in JDK 11+ to make a simple HTTPS GET request. We create an instance of HttpClient
using the newBuilder()
method, and then build a GET request using HttpRequest.newBuilder()
. Finally, we send the request using httpClient.send()
and handle the response accordingly.
Note that in this new approach, you don’t need to set a custom SSL socket factory explicitly. The HttpClient
class handles SSL/TLS configurations automatically based on the system’s trust store and other security settings.
