我已经在glassfish上部署了一个Web应用程序，在那里我在web.xml中有一个会话超时：
<session-config>
<session-timeout>
1
</session-timeout>
</session-config>
在我添加WebSockets之前一切正常
前端：
var webSocket = new WebSocket('#{authenticationJSFBean.webSocketURL}');
webSocket.onmessage = function(message){
switch(message.data) {
case 'sendRegistrationRequest':
updateNewRegistrationRequestCount();
break;
case 'sendStageRequest':
updateSourceAndTargetParticipatingCompaniesDataTables();
break;
};
后端：
@ServerEndpoint("/websocket/{login}")
public class WebSocketEndpoint {
private static final Set<Session> sessions = new CopyOnWriteArraySet<>();
private static final Logger LOG = LogManager.getLogger(WebSocketEndpoint.class);
@OnOpen
public void onOpen(@PathParam("login") String login, Session peer) {
sessions.add(peer);
}
@OnClose
public void onClose(Session peer) {
if(sessions.contains(peer)) {
sessions.remove(peer);
}
}
public static void sendMessage(String message) {
for(Session session : sessions) {
RemoteEndpoint.Basic endpoint = session.getBasicRemote();
try {
endpoint.sendText(message);
} catch(IOException ioe) {
LOG.warn("Unable to send message to session\n Message:" + ioe.getMessage());
}
}
}
}
添加此内容后，会话超时停止工作。我试图在websocket会话中设置超时时间：
peer.setMaxIdleTimeout(60 * 60 * 1000);
起初看起来很有帮助，但是在第二或第三次会议上我遇到了错误：

并且超时完全停止工作。如何解决？
