      booleanisRunning()
      Check whether this component is currently running.
      voidstart()
      Start this component.
      voidstop()
      Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method.
    • 方法详细资料

      • start

        void start()
        Start this component.

        Should not throw an exception if the component is already running.

        In the case of a container, this will propagate the start signal to all components that apply.

      • stop

        void stop()
        Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.

        Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, a given bean's destroy method will be called without any consideration of stop signals upfront.

        Should not throw an exception if the component is not running (not started yet).

        In the case of a container, this will propagate the stop signal to all components that apply.

      • isRunning

        boolean isRunning()
        Check whether this component is currently running.

        In the case of a container, this will return true only if all components that apply are currently running.

        返回:
        whether the component is currently running
