我已经实现了一个非常非常简单的 Java 服务器，它基本上监听 8080 端口上的所有请求并将它们写入控制台。

我的代码运行良好，一次。但是对于每次应用程序重启，服务器只会接受一个请求。有谁能够帮我？

服务器代码：

public class RunServer {

    public static void main(String[] args) {
        final int port = 8080;
        final String path = "/android";
        try {
            HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);     //Create the server to listen for incoming requests on the specified port
            server.createContext(path, new HttpHandler() { //Set a handler for     incoming requests to the specific path
                @Override
                public void handle(HttpExchange arg0) throws IOException {     //This method is called when new requests are incoming
                            InputStreamReader isr = new     InputStreamReader(arg0.getRequestBody(),"utf-8");
                            BufferedReader br = new BufferedReader(isr);
                            String query = br.readLine();

                            System.out.print(query);
                } });           
            server.setExecutor(null); //Default executor. Other executors may be     used to e.g. use a threadpool for handling concurrent incoming requests.
            server.start(); //Start the server.
        } catch (Exception e) {
            e.printStackTrace();
        }       
    }
}

我正在使用此客户端发布到我的服务器：

public class MyAsyncTask extends AsyncTask<String, String, Void>{
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost("http://192.168.1.5:8080/android");
    String s;
    @Override
    protected Void doInBackground(String... params) {
        // Building post parameters
        // key and value pair
        List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
        nameValuePair.add(new BasicNameValuePair("email", "user@gmail.com"));
        nameValuePair.add(new BasicNameValuePair("message",
                "Hi, trying Android HTTP post!"));

        // Url Encoding the POST parameters
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
        } catch (UnsupportedEncodingException e) {
            // writing error to Log
            e.printStackTrace();
        }

        // Making HTTP Request
        try {
            HttpResponse response = httpClient.execute(httpPost);

            // writing response to log
            Log.d("Http Response:", response.toString());
        } catch (ClientProtocolException e) {
            // writing exception to log
            e.printStackTrace();
        } catch (IOException e) {
            // writing exception to log
            e.printStackTrace();

        }
        return null;
    }

}

如果您要进行任何稍微严肃的 Java HTTP 服务，最好使用Jetty或Tomcat之类的东西。

如果您要坚持使用 HttpServer，实际上并不真正了解它，我怀疑这与 HttpServer 在其默认配置中的单线程性质以及套接字保持打开并等待一段时间后的特性有关。也可能是您没有正确关闭 Android 客户端中的 HttpClient ，因此它使与服务器的连接保持打开状态，因此服务器被捆绑等待该客户端。
