java - Executorservice worker 没有在单独的线程中运行

Question

我正在使用 newFixedThreadPool 来同时处理对服务器套接字的传入请求。出于某种原因，服务于客户端的工作类没有在单独的线程中运行。当我向套接字发送多个请求时，请求会按顺序处理，而不是像它们应该的那样同时处理。如果有任何不同，我正在运行 OpenJDK 1.8.0_77。

这是我主课的摘录:

    ExecutorService executorService = Executors.newFixedThreadPool(100);
    ServerSocket serverSocket = new ServerSocket(5656);

    while(true) {
        Socket socket = serverSocket.accept();
        executorService.execute(new ConnectionHandler(socket));
    }

这是我的 worker 类(Class):

    public class ConnectionHandler implements Runnable {

    private Socket socket;

    public ConnectionHandler(Socket socket) {
        this.socket = socket;
    }

    public void run() {

        try {
            Thread.sleep(5000);
        } catch (InterruptedException e1) {
            e1.printStackTrace();
        }

        BufferedReader reader = null;
        PrintWriter writer = null;
        try {
        reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        writer = new PrintWriter(socket.getOutputStream(), true);

        while(true) {
            String line = reader.readLine();
            if(line == null) break;
            writer.println("Echo: " + line);
        }
        } catch (IOException e) {
        throw new RuntimeException(e);
        } finally {
        try {
            if(reader != null) reader.close();
            if(writer != null) writer.close();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        }
    }

    }

对不起，我不会电脑。

问题是我在循环中将许多消息回显到套接字，但是 echo 命令按顺序发送消息并等待每条消息完成后再发送下一条消息。
