无法使用任何 TLS 版本的 splunk-java sdk 连接到 splunk

Question

我已按照 这些 示例来连接 splunk使用java-sdk。但我无法使用 此示例。在我的情况下，禁用安全性（提供的连接选项之一）不是一个可行的选择。如果有人成功使用这些选项，我真的很感谢您的帮助。到目前为止我尝试过的Java版本是openjdk 8,11 &17。

 ServiceArgs loginArgs = new ServiceArgs();
    loginArgs.setUsername("username");
    loginArgs.setPassword("password");
    loginArgs.setScheme("https");
    loginArgs.setHost("network-splunk-hostname");
    loginArgs.setPort(443);

    // Create a Service instance and log in with the argument map
    //Service service = Service.connect(loginArgs);

    try {
        Service.setSslSecurityProtocol(SSLSecurityProtocol.SSLv3);
        Service serviceSSLv3 = Service.connect(loginArgs);
        serviceSSLv3.login();
        System.out.println("\t Success!");
    } catch (RuntimeException e) {
        System.out.println("\t Failure! ");
    }

    // TLSv1 is available by default in every modern version of Java
    System.out.println("Now trying to connect to Splunk using TLSv1");
    try {
        Service.setSslSecurityProtocol(SSLSecurityProtocol.TLSv1);
        Service serviceTLSv1 = Service.connect(loginArgs);
        serviceTLSv1.login();
        System.out.println("\t Success!");
    } catch (RuntimeException e) {
        System.out.println("\t Failure! ");
    }


    // TLSv1.1 is available by default in Java 7 and up
    System.out.println("Now trying to connect to Splunk using TLSv1.1");
    try {
        Service.setSslSecurityProtocol(SSLSecurityProtocol.TLSv1_1);
        Service serviceTLSv1_1 = Service.connect(loginArgs);
        serviceTLSv1_1.login();
        System.out.println("\t Success!");
    } catch (RuntimeException e) {
        System.out.println("\t Failure! ");
    }

    // TLSv1.2 is available by default in Java 7 and up
    System.out.println("Now trying to connect to Splunk using TLSv1.2");
    try {
        Service.setSslSecurityProtocol(SSLSecurityProtocol.TLSv1_2);
        Service serviceTLSv1_2 = Service.connect(loginArgs);
        serviceTLSv1_2.login();
        System.out.println("\t Success!");
    } catch (RuntimeException e) {
        System.out.println("\t Failure! ");
    }

    // You can also specify your own SSLSocketFactory, in this case any version of SSL
    System.out.println("Now trying to connect to Splunk using a custom SSL only SSLSocketFactory");
    try {

                        return null;
                    }

                    public void checkClientTrusted(X509Certificate[] chain, String authType) {
                    }

                    public void checkServerTrusted(X509Certificate[] chain, String authType) {

        };
        sslContext.init(null, byPassTrustManagers, new SecureRandom());
        SSLSocketFactory SSLOnlySSLFactory = sslContext.getSocketFactory();
        Service.setSSLSocketFactory(SSLOnlySSLFactory);

        Service serviceCustomSSLFactory = Service.connect(loginArgs);
        serviceCustomSSLFactory.login();
        System.out.println("\t Success!");
    } catch (Exception e) {
        System.out.println("\t Failure!");
    }

    // You can also specify your own SSLSocketFactory, in this case any version of TLS
    System.out.println("Now trying to connect to Splunk using a custom TLS only SSLSocketFactory");
    try {
        // Create an SSLSocketFactory configured to use TLS only
        SSLContext sslContext = SSLContext.getInstance("TLS");
        TrustManager[] byPassTrustManagers = new TrustManager[]{

        serviceCustomSSLFactory.login();
        System.out.println("\t Success!");
    } catch (Exception e) {
        System.out.println("\t Failure!");
    }

输出是：

---

失败！

现在尝试使用 TLSv1 连接到 Splunk 失败！

现在尝试使用 TLSv1.1 连接到 Splunk 失败！

现在尝试使用 TLSv1.2 连接到 Splunk 失败！

现在尝试使用仅自定义 SSL SSLSocketFactory 连接到 Splunk 失败！
