Spring 4 + Websockets: how to close the session?

I am using Spring 4 + Websockets + Stomp JS library. I could not find any way to setup websocket ping/pong mechanism (heartbeat).

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans" ...">

<websocket:message-broker>
    <websocket:stomp-endpoint path="/cors/auth/clientEndpoint">
        <websocket:handshake-handler ref="myHandshakeHandler" />
    </websocket:stomp-endpoint>
    <websocket:simple-broker prefix="/queue, /topic" />
    <websocket:client-inbound-channel>
        <websocket:interceptors>
            <bean class="com.mycompany.myproject.utils.messaging.MyInboundChannelInterception"></bean>
        </websocket:interceptors>
    </websocket:client-inbound-channel>
</websocket:message-broker>

<bean id="myHandshakeHandler" class="com.mycompany.myproject.utils.security.MyHandshakeHandler" />

<bean class="org.springframework.web.socket.server.standard.ServletServerContainerFactoryBean">
    <property name="maxSessionIdleTimeout" value="120000" />
</bean>

As result, I am implementing my own mechanism of ping/pong messages.

One of the tasks here - to implement server side closure of the websocket in case if no ping message during more than 10s from client.

And no way to do this using Spring Websockets!

Maybe somebody can tell me how to access Session object of the user or to close those Session via Spring Websockets?

Seems Spring is very limited here.

Solution

  • In this case, configuring SockJS in your app could go a long way:

    <websocket:stomp-endpoint path="/cors/auth/clientEndpoint">
  <websocket:handshake-handler ref="myHandshakeHandler" />
  <websocket:sockjs/>
</websocket:stomp-endpoint>

    This will give you:

    If you want to actually close a session from STOMP endpoints, then I suggest you to vote/follow the SPR-12288 JIRA issue.
