在Java11中，配置也类似这个链接中：http://www.cjavapy.com/article/52/，具体代码如下,
package Demo;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

}
@Override

} };
//HostnameVerifier trustAllHostnames = new HostnameVerifier() {

// }
};
var timeoutInSeconds = 60;
SSLParameters sslParams = new SSLParameters();
sslParams.setEndpointIdentificationAlgorithm("");
SSLContext sc = SSLContext.getInstance("SSL");
System.setProperty("jdk.internal.httpclient.disableHostnameVerification","true");//取消主机名验证
sc.init(null, trustAllCertificates, new SecureRandom());
HttpClient httpClient = HttpClient.newBuilder().connectTimeout(Duration.ofMillis(timeoutInSeconds * 1000))
.sslContext(sc)
.sslParameters(sslParams)
.build();
HttpRequest requestBuilder = HttpRequest.newBuilder().uri(URI.create("https://www.example.com/getSomething"))
.GET().build();
HttpResponse<String> result = httpClient.send(requestBuilder, HttpResponse.BodyHandlers.ofString()); //发送请求
}
}
