Jetty 9 RC2 websocket timeout

Question

Answer 1

支持session。最近添加了setIdleTimeout(长毫秒)，以支持我们目前正在做的JSR-356 (javax.websocket)工作。

然而，在9.0.0。在RC2中，您可以执行以下操作，以便在创建会话之前尽早设置空闲超时(这正在修复，希望将在RC3中实现)

服务器端选项A: WebSocketServlet init-param

在websocket servlet的WEB-INF/web.xml中，指定以下初始化参数

<init-param>
  <param-name>maxIdleTime</param-name>
  <param-value>10000</param-value>
</init-param>

Server Side option B: As policy change on WebSocketFactory

在你的WebSocketServlet。配置(WebSocketServletFactory factory)调用

@Override
public void configure(WebSocketServletFactory factory)
{
    factory.getPolicy().setIdleTimeout(10000);
}

客户端选项A: As WebSocketClient设置

WebSocketClient client = new WebSocketClient();
client.getPolicy().setIdleTimeout(10000);
client.start();

带注释的@WebSocket选项

这将适用于服务器端或客户端websockets。

注意:你不能把WebSocketListener和@WebSocket注释混合在一起

import org.eclipse.jetty.websocket.api.Session;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketClose;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketConnect;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketError;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketMessage;
import org.eclipse.jetty.websocket.api.annotations.WebSocket;
@WebSocket(maxIdleTime=10000)
public class MySocket
{
    @OnWebSocketClose
    public void onClose(int statusCode, String reason)
    {
    }
    @OnWebSocketConnect
    public void onConnect(Session sess)
    {
    }
    @OnWebSocketError
    public void onError(Throwable cause)
    {
    }
    @OnWebSocketMessage
    public void onText(String message)
    {
    }
}
