WebSocket 経由で 4M を超えるファイルを転送しようとしています。私は依存関係としてorg.glassfish.tyrus:tyrus-server:1.13.1andを使用しています。org.glassfish.tyrus:tyrus-container-grizzly-server:1.13.1
デフォルトでは、着信バッファ サイズは約 4M です (「8.4. 着信バッファ サイズ」を参照)。ドキュメントには、ファイルのサイズを大きくしたいが、受信バッファーのサイズを変更できない場合に何をする必要があるかが明確に記載されています。これが私がやろうとしていることの本質です：
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);
しかし、私はまだ同じエラーがあります:
17000000
4734639

Tyrus プロジェクトをデバッグしようとしたところ、incomingBufferSize変数が実際にはデフォルト値のままであることがわかりました。
どうすればこれを修正できますか？
