Class ConnectionManagerSupport

java.lang.Object
org.springframework.web.socket.client.ConnectionManagerSupport
All Implemented Interfaces:
org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle
Direct Known Subclasses:
AnnotatedEndpointConnectionManager, EndpointConnectionManager, WebSocketConnectionManager
public abstract class ConnectionManagerSupport extends Object implements org.springframework.context.SmartLifecycle
A base class for WebSocket connection managers. Provides a declarative style of connecting to a WebSocket server given a URI to connect to. The connection occurs when the Spring ApplicationContext is refreshed, if the autoStartup property is set to true, or if set to false, the start() and #stop methods can be invoked manually.

    • setAutoStartup

      public void setAutoStartup(boolean autoStartup)
      Set whether to auto-connect to the remote endpoint after this connection manager has been initialized and the Spring context has been refreshed.

      Default is "false".

    • isAutoStartup

      public boolean isAutoStartup()
      Return the value for the 'autoStartup' property. If "true", this endpoint connection manager will connect to the remote endpoint upon a ContextRefreshedEvent.
      Specified by:
      isAutoStartup in interface org.springframework.context.SmartLifecycle

    • setPhase

      public void setPhase(int phase)
      Specify the phase in which a connection should be established to the remote endpoint and subsequently closed. The startup order proceeds from lowest to highest, and the shutdown order is the reverse of that. By default this value is Integer.MAX_VALUE meaning that this endpoint connection factory connects as late as possible and is closed as soon as possible.

    • getPhase

      public int getPhase()
      Return the phase in which this endpoint connection factory will be auto-connected and stopped.
      Specified by:
      getPhase in interface org.springframework.context.Phased
      Specified by:
      getPhase in interface org.springframework.context.SmartLifecycle

    • start

      public final void start()
      Start the WebSocket connection. If already connected, the method has no impact.
      Specified by:
      start in interface org.springframework.context.Lifecycle

    • startInternal

      protected void startInternal()

    • stop

      public final void stop()
      Specified by:
      stop in interface org.springframework.context.Lifecycle

    • stop

      public final void stop(Runnable callback)
      Specified by:
      stop in interface org.springframework.context.SmartLifecycle

    • stopInternal

      protected void stopInternal() throws Exception
      Throws:
      Exception

    • isRunning

      public boolean isRunning()
      Return whether this ConnectionManager has been started.
      Specified by:
      isRunning in interface org.springframework.context.Lifecycle

    • openConnection

      protected abstract void openConnection()

    • closeConnection

      protected abstract void closeConnection() throws Exception
      Throws:
      Exception

    • isConnected
