我试图通过 WebSocket 传输大于 4M 的文件。我正在使用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. 传入缓冲区大小）。文档清楚地说明了如果我想增加文件大小但仍然无法更改传入缓冲区大小需要做什么。这是我正在尝试做的事情的本质：
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：
17000000
4734639

我尝试调试 Tyrus 项目，发现incomingBufferSize变量实际上保持默认值。
有谁知道我该如何解决这个问题？
