无法将传入缓冲区大小设置为 Tyrus 客户端

Question

我试图通过 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的大小但仍然无法更改传入缓冲区大小需要做什么。这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 变量实际上保持默认值。

有人知道我该如何解决这个问题吗？

Answer 1

你在客户端设置了属性，但是服务端明明抛出了异常

你是如何启动服务器的？似乎您正在独立使用 Grizzly - 如果您这样做，您可以尝试将 TyrusWebSocketEngine#INCOMING_BUFFER_SIZE 属性设置为 17_000_000 或您想要的任何值来启动服务器。

（可以通过使用 Server(Map, Class ...) or other constructors. See Server class javadoc 创建服务器来完成更多详细信息。

Answer 2

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);

无法将传入缓冲区大小设置为 Tyrus 客户端

Incoming buffer size cannot be set to Tyrus client
