如何使用线程池优化Java网站的访问速度？

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadPoolExample {
    public static void main(String[] args) {
        // 创建线程池，设置线程池大小为10
        ExecutorService executor = Executors.newFixedThreadPool(10);
        
        // 提交任务到线程池，这里以处理请求为例
        for (int i = 0; i < 100; i++) {
            executor.submit(new RequestHandler());
        }
        
        // 关闭线程池
        executor.shutdown();
    }
}

class RequestHandler implements Runnable {
    @Override
    public void run() {
        // 处理请求的逻辑，这里只是模拟耗时的操作
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Request handled by thread: " + Thread.currentThread().getName());
    }
}

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class WebServer {
    private ExecutorService executor;  // 线程池
    
    public void init() {
        // 创建线程池，根据服务器的处理能力来设置线程池大小
        executor = Executors.newFixedThreadPool(100);
    }
    
    public void handleRequest(Request request) {
        // 提交请求到线程池进行处理
        executor.submit(() -> {
            // 处理请求的逻辑
            Response response = processRequest(request);
            // 返回处理结果给客户端
            return response;
        });
    }
    
    public void shutdown() {
        // 关闭线程池
        executor.shutdown();
    }
    
    private Response processRequest(Request request) {
        // 处理请求的逻辑，这里只是模拟耗时的操作
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Request handled by thread: " + Thread.currentThread().getName());
        
        // 返回处理结果
        return new Response("Hello, World!");
    }
}

class Request {
    // 请求类，可以根据具体业务需要自定义请求类的内容
}

class Response {
    private String content;
    
    public Response(String content) {
        this.content = content;
    }
    
    public String getContent() {
        return content;
    }
}
