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作为依赖关系。传入缓冲区大小不能设置为Tyrus客户端
默认情况下，传入缓冲区大小约为4M（请参阅：8.4. Incoming buffer size）。文档清楚地说明如果我想增加文件的大小，但仍然不能改变传入的缓冲区大小，需要做些什么。这里是我想要做的精髓：
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

我试着调试泰鲁斯项目，只见那incomingBufferSize变量实际上仍与默认值。
有没有人有任何想法我该如何解决这个问题？
我已经解决了一个问题，感谢您的回复。我将新的传入缓冲区大小的映射注入到服务器构造函数中，并解决了我的问题。非常感谢！ – dim
