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，传入的缓冲区大小约为4m(请参阅：8.4。输入缓冲区大小(。文档清楚地说明，如果我想增加文件的大小，但仍然无法更改传入的缓冲区大小，该怎么办。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);
但我仍然有相同的错误：
17000000
4734639

我尝试调试Tyrus项目，并发现incomingBufferSize变量实际上保留在默认值中。
有人知道我该如何解决？
您是在客户端中设置属性，但是显然会在服务器上抛出例外。
您如何启动服务器？看来您正在使用灰色独立的人 - 如果这样做，可以尝试使用TyrusWebSocketEngengine＃incoming_buffer_size属性设置为17_000_000或您想要的任何值。
(可以通过使用服务器(MAP，类...(或其他构造函数来创建服务器。有关更多详细信息，请参见Server Class Javadoc。
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);
