如何使用Smack XMPP库创建SSL连接？

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;

ConnectionConfiguration config = new XMPPTCPConnectionConfiguration.Builder()
    .setHost("your-xmpp-server-host")
    .setPort(5223)
    .setSecurityMode(ConnectionConfiguration.SecurityMode.required)
    .build();

XMPPTCPConnection connection = new XMPPTCPConnection(config);

connection.connect();

connection.login("your-username", "your-password");
