How to hook Post Login and Pre Login actions or events in Liferay 7

How to Hook Login Events in Liferay 7 ?

In this tutorial we are going to learn how we can hook the Login POST and PRE actions in liferay 7. To hook the post login or pre login event we need to use the liferay's com.liferay.portal.kernel.events.LifecycleAction  class to process the events.

As we know that everything in liferay 7 is a component and we need to define this too as a component using the @Component annotation. In the component we  need to define the LifecycleAction.class as a service.  So the final @Component setup will look like this.

For Post Login Event we need to setup the @Component like this -:

@Component(
immediate = true, property = {"key=login.events.post"},
service = LifecycleAction.class
)

For Pre Login Event we need to setup the @Component like this -:

@Component(
immediate = true, property = {"key=login.events.pre"},
service = LifecycleAction.class

)

In both of the cases we need to implement the method processLifecycleEvent(LifecycleEvent lifecycleEvent) .

So below is the code snippet for both of the events.
