public interface LifecycleBean
LifecycleEventType.
Use this bean whenever you need to plug some custom logic before or after
node startup and stopping routines.
There are four events you can react to:
LifecycleEventType.BEFORE_NODE_START invoked before node startup
routine is initiated. Note that node is not available during this event,
therefore if you injected a ignite instance via IgniteInstanceResource
annotation, you cannot use it yet.
LifecycleEventType.AFTER_NODE_START invoked right after node
has started. At this point, if you injected a node instance via
IgniteInstanceResource annotation, you can start using it. Note that
you should not be using Ignition to get node instance from
lifecycle bean.
LifecycleEventType.BEFORE_NODE_STOP invoked right before node
stop routine is initiated. Node is still available at this stage, so
if you injected a ignite instance via IgniteInstanceResource annotation,
you can use it.
LifecycleEventType.AFTER_NODE_STOP invoked right after node
has stopped. Note that node is not available during this event.
IGNITE_HOME/libs folder, and
simply start IGNITE_HOME/ignite.{sh|bat} scripts.
IgniteConfiguration cfg = new IgniteConfiguration(); cfg.setLifecycleBeans(new FooBarLifecycleBean1(), new FooBarLifecycleBean2()); // Start grid with given configuration. Ignition.start(cfg);or from Spring XML configuration file as follows:
<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
...
<property name="lifecycleBeans">
<list>
<bean class="foo.bar.FooBarLifecycleBean1"/>
<bean class="foo.bar.FooBarLifecycleBean2"/>
</list>
</property>
...
</bean>
