如何使用类加载器将类文件从服务器端加载到客户端

import java.io.*;
import java.net.*;

public class CustomClassLoader extends ClassLoader {
    private String serverUrl; // 服务器地址

    public CustomClassLoader(String serverUrl) {
        this.serverUrl = serverUrl;
    }

    @Override
    protected Class<?> findClass(String name) throws ClassNotFoundException {
        try {
            // 从服务器下载类文件
            byte[] classData = downloadClassData(name);
            // 将类文件转换为Class对象
            return defineClass(name, classData, 0, classData.length);
        } catch (IOException e) {
            throw new ClassNotFoundException("Class not found: " + name, e);
        }
    }

    private byte[] downloadClassData(String className) throws IOException {
        // 构建类文件的URL
        String classUrl = serverUrl + className.replace('.', '/') + ".class";
        URL url = new URL(classUrl);
        // 打开URL连接
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        try (InputStream input = connection.getInputStream();
             ByteArrayOutputStream output = new ByteArrayOutputStream()) {
            // 读取类文件数据
            byte[] buffer = new byte[4096];
            int bytesRead;
            while ((bytesRead = input.read(buffer)) != -1) {
                output.write(buffer, 0, bytesRead);
            }
            return output.toByteArray();
        }
    }
}

CustomClassLoader classLoader = new CustomClassLoader("http://example.com/classes/");

Class<?> clazz = classLoader.loadClass("com.example.MyClass");
