做一個讀取html文件的服務端

public class 讀取html文件的服務端 {
	public static void main(String[] args) throws Exception {
		//創建服務器端的socket
		ServerSocket sersocket=new ServerSocket(8080);
		while(true){
			//接收瀏覽器的請求
			Socket socket=sersocket.accept();
			ExecutorService tool=Executors.newFixedThreadPool(2);
			tool.submit(new Runnable() {
				
				@Override
				public void run() {
			           try {

	                        // 將瀏覽器發送過來的字節輸入流，轉換爲字符緩衝輸入流

	                        //3.響應瀏覽器的請求,向瀏覽器發送數據

	                        byte[] bytes = new byte[1024];
	                        int len = 0;
