问题
I trying to transfer a file bigger than 4M via WebSocket. I'm using org.glassfish.tyrus:tyrus-server:1.13.1 and org.glassfish.tyrus:tyrus-container-grizzly-server:1.13.1 as dependencies.
By default the incoming buffer size is about 4M (see: 8.4. Incoming buffer size). The documentation clearly says what needs to be done if I want to increase the size of the file but still can not change the incoming buffer size. Here is the essence of what I'm trying to do:
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);
But I still have the same error:
17000000
4734639

I tried to debug the Tyrus project and saw that the incomingBufferSize variable actually remained with the default value.
Does anyone have any idea how can I fix this?
回答1:
You are setting the property in the client, but the exception is clearly thrown on the server.
How are you starting the server? It almost seems like you are using Grizzly standalone - if you do, you can try starting the server with TyrusWebSocketEngine#INCOMING_BUFFER_SIZE property set to 17_000_000 or whatever value you want.
(That can be done by creating the server by using Server(Map, Class ...) or other constructors. See Server class javadoc for more details.
回答2:
Solution (thanks to @Pavel Bucek):
On the Server side:
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);
