使用java代码分别演示通过Tor网络、VPN、使用Netty或Apache HttpClient、JCE加密通信等手段伪装真实ip的具体代码？所有案例都要包含依赖坐标以及对应技术对服务器端的要求？

通过Tor网络伪装真实IP：

import org.jsoup.Connection;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class TorExample {
    public static void main(String[] args) throws Exception {
        System.setProperty("socksProxyHost", "127.0.0.1");
        System.setProperty("socksProxyPort", "9050");

        Connection connection = Jsoup.connect("https://www.example.com/");
        connection.userAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3");
        Document document = connection.get();

        System.out.println(document.html());
    }
}

依赖坐标：

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.13.1</version>
</dependency>

服务器端要求：Tor网络配置正确，并且运行在本地的9050端口。

通过VPN伪装真实IP：

import org.apache.http.HttpHost;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class VpnExample {
    public static void main(String[] args) throws Exception {
        HttpHost proxy = new HttpHost("vpn.example.com", 8080, "http");
        CloseableHttpClient httpClient = HttpClientBuilder.create().setProxy(proxy).build();
        HttpGet request = new HttpGet("https://www.example.com/");
        CloseableHttpResponse response = httpClient.execute(request);

        String html = EntityUtils.toString(response.getEntity());
        System.out.println(html);

        httpClient.close();
    }
}

依赖坐标：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

服务器端要求：VPN服务器配置正确，并且能够正常连接。

使用Netty或Apache HttpClient伪装真实IP：

Netty示例：

import io.netty.bootstrap.Bootstrap;
import io.netty.channel.Channel;
import io.netty.channel.ChannelInitializer;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.SocketChannel;
import io.netty.channel.socket.nio.NioSocketChannel;
import io.netty.handler.codec.http.DefaultFullHttpRequest;
import io.netty.handler.codec.http.HttpMethod;
import io.netty.handler.codec.http.HttpRequest;
import io.netty.handler.codec.http.HttpVersion;
import io.netty.handler.ssl.SslContext;
import io.netty.handler.ssl.SslContextBuilder;
import io.netty.handler.ssl.util.InsecureTrustManagerFactory;

import java.net.URI;

public class NettyExample {
    public static void main(String[] args) throws Exception {
        URI uri = new URI("https://www.example.com/");
        String host = uri.getHost();
        int port = uri.getPort() != -1 ? uri.getPort() : 443;

        EventLoopGroup group = new NioEventLoopGroup();
        try {
            SslContext sslContext = SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build();

            Bootstrap bootstrap = new Bootstrap();
            bootstrap.group(group)
                    .channel(NioSocketChannel.class)
                    .option(ChannelOption.SO_KEEPALIVE, true)
                    .handler(new ChannelInitializer<SocketChannel>() {
                        @Override
                        protected void initChannel(SocketChannel ch) {
                            ch.pipeline().addLast(sslContext.newHandler(ch.alloc(), host, port));
                        }
                    });

            Channel channel = bootstrap.connect(host, port).sync().channel();

            HttpRequest request = new DefaultFullHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.GET, uri.getRawPath());
            channel.writeAndFlush(request);

            // Read response...

            channel.closeFuture().sync();
        } finally {
            group.shutdownGracefully();
        }
    }
}

依赖坐标：

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.68.Final</version>
</dependency>

Apache HttpClient示例：

import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class ApacheHttpClientExample {
    public static void main(String[] args) throws Exception {
        HttpHost proxy = new HttpHost("proxy.example.com", 8080, "http");
        CloseableHttpClient httpClient = HttpClientBuilder.create().setProxy(proxy).build();
        HttpGet request = new HttpGet("https://www.example.com/");
        HttpResponse response = httpClient.execute(request);

        String html = EntityUtils.toString(response.getEntity());
        System.out.println(html);

        httpClient.close();
    }
}

依赖坐标：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

服务器端要求：服务器能够正常处理HTTPS请求。

使用JCE加密通信伪装真实IP：

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.security.Key;

public class JCEExample {
    public static void main(String[] args) throws Exception {
        String secretKey = "0123456789abcdef";
        String message = "Hello World!";

        Key key = new SecretKeySpec(secretKey.getBytes(StandardCharsets.UTF_8), "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key);

        byte[] encryptedBytes = cipher.doFinal(message.getBytes(StandardCharsets.UTF_8));
        String encryptedMessage = new String(encryptedBytes, StandardCharsets.UTF_8);

        System.out.println("Encrypted message: " + encryptedMessage);
    }
}

依赖坐标：无需依赖。

服务器端要求：无特殊要求
