public interface Lifecycle
Can be implemented by both components (typically a Spring bean defined in
a Spring BeanFactory
) and containers
(typically a Spring ApplicationContext
). Containers will propagate
start/stop signals to all components that apply.
Can be used for direct invocations or for management operations via JMX.
In the latter case, the MBeanExporter
will typically be defined with an
InterfaceBasedMBeanInfoAssembler
,
restricting the visibility of activity-controlled components to the Lifecycle
interface.
Note that the Lifecycle interface is only supported on top-level singleton beans.
On any other component, the Lifecycle interface will remain undetected and hence ignored.
Also, note that the extended SmartLifecycle
interface provides more sophisticated
integration with the container's startup and shutdown phases.

Modifier and Type | Method and Description |
---|---|
boolean |
isRunning()
Check whether this component is currently running.
|
void |
start()
Start this component.
|
void |
stop()
Stop this component, typically in a synchronous fashion, such that
the component is fully stopped upon return of this method.
|
void start()
In the case of a container, this will propagate the start signal to all components that apply.
void stop()
SmartLifecycle
and its stop(Runnable)
variant in cases where asynchronous stop behavior is necessary.
Should not throw an exception if the component isn't started yet.
In the case of a container, this will propagate the stop signal to all components that apply.
SmartLifecycle.stop(Runnable)
boolean isRunning()
In the case of a container, this will return true
only if all components that apply are currently running.
