有没有一种方法可以将SocketFactory _instance_提供给InitialLdapContext？

import javax.naming.Context;
import javax.naming.directory.InitialDirContext;
import javax.naming.ldap.InitialLdapContext;
import javax.net.SocketFactory;
import java.util.Hashtable;

public class LdapExample {
    public static void main(String[] args) {
        try {
            // 创建自定义的SocketFactory类
            SocketFactory customSocketFactory = new CustomSocketFactory();

            // 创建连接LDAP服务器所需的环境属性
            Hashtable<String, Object> env = new Hashtable<>();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.PROVIDER_URL, "ldap://ldap.example.com:389");
            env.put(Context.SECURITY_AUTHENTICATION, "simple");
            env.put(Context.SECURITY_PRINCIPAL, "cn=admin,dc=example,dc=com");
            env.put(Context.SECURITY_CREDENTIALS, "password");

            // 将自定义的SocketFactory实例提供给InitialLdapContext
            env.put("java.naming.ldap.factory.socket", customSocketFactory);

            // 创建InitialLdapContext对象
            InitialLdapContext context = new InitialLdapContext(env, null);

            // 进行LDAP操作...

            // 关闭连接
            context.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    static class CustomSocketFactory implements SocketFactory {
        @Override
        public Socket createSocket() {
            // 创建和配置Socket实例
            // 这里可以使用任何适合与LDAP服务器建立安全连接的Socket实现
            // 例如，可以使用SSLSocket来建立安全连接
            return null;
        }

        @Override
        public Socket createSocket(String s, int i) {
            return null;
        }

        @Override
        public Socket createSocket(String s, int i, InetAddress inetAddress, int i1) {
            return null;
        }

        @Override
        public Socket createSocket(InetAddress inetAddress, int i) {
            return null;
        }

        @Override
        public Socket createSocket(InetAddress inetAddress, int i, InetAddress inetAddress1, int i1) {
            return null;
        }
    }
}
