Events (Application event)

Spring Events (Appllcation event) provide support for message communication between beans and beans. When a bean finishes a task, it wants another bean to know and handle it, which allows another bean to listen for events sent by the current bean

The spring events need to follow the following process:

1. Custom events, inheriting applicationevent

2, define the event listener, realize Applicationlistener

3. Publish Events using containers
