传入缓冲区大小无法设置为Tyrus客户端

标签： java websocket glassfish java-websocket tyrus

我尝试通过WebSocket传输大于4M的文件。我使用org.glassfish.tyrus:tyrus-server:1.13.1和org.glassfish.tyrus:tyrus-container-grizzly-server:1.13.1作为依赖项。

默认情况下，传入缓冲区大小约为4M（请参阅：8.4. Incoming buffer size）。文档清楚地说明了如果我想增加文件大小但仍无法更改传入缓冲区大小需要做什么。以下是我要做的事情的本质：

CountDownLatch messageLatch = new CountDownLatch(1);

final ClientEndpointConfig cec = ClientEndpointConfig.Builder.create().build();
ClientManager client = ClientManager.createClient();

client.getProperties().put(ClientProperties.INCOMING_BUFFER_SIZE, new Integer(17_000_000));
Integer tyrusIncomingBufferSize = Utils.getProperty(client.getProperties(), ClientProperties.INCOMING_BUFFER_SIZE, Integer.class);
System.out.println("tyrusIncomingBufferSize: " + tyrusIncomingBufferSize); // 17000000

client.connectToServer(new Endpoint() {
    @Override
    public void onOpen(Session session, EndpointConfig config) {
        try {
            session.addMessageHandler(new MessageHandler.Whole<ByteBuffer>() {

                @Override
                public void onMessage(ByteBuffer message) {
                    System.out.println("Received message: " + message);
                    messageLatch.countDown();
                }
            });

            File pic = new File(TEST_PIC); // the size is more than 4M
            FileInputStream fileReader = new FileInputStream(pic);
            final long sizeOfScreenshotFile = pic.length();
            System.out.println(sizeOfScreenshotFile); // 4734639
            byte[] screenshotData = new byte[(int) sizeOfScreenshotFile];
            fileReader.read(screenshotData);
            fileReader.close();

            ByteBuffer bb = ByteBuffer.wrap(screenshotData);
            session.getBasicRemote().sendBinary(bb);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}, cec, new URI(URI));
messageLatch.await(100, TimeUnit.SECONDS);

但我仍然有同样的错误：

我尝试调试Tyrus项目，发现incomingBufferSize变量实际上保留了默认值。

有谁知道如何解决这个问题？

您正在客户端中设置属性，但服务器上明显抛出异常。

你是如何启动服务器的？您似乎正在使用Grizzly独立 - 如果您这样做，您可以尝试启动服务器，将TyrusWebSocketEngine#INCOMING_BUFFER_SIZE属性设置为17_000_000或您想要的任何值。

（可以通过使用Server(Map, Class ...)或其他构造函数创建服务器来完成。有关详细信息，请参阅Server class javadoc。

解决方案（感谢@Pavel Bucek）：

在服务器端：

Map<String,Object> properties = new HashMap<String, Object>();
properties.put("org.glassfish.tyrus.incomingBufferSize", 17000000);
Server server = new org.glassfish.tyrus.server.Server("localhost", 8025, null, 
                                               properties, TestServer.class);
