The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization.

The PreDestroy annotation is used on methods as a callback notification to signal that the instance is in the process of being removed by the container.

Description

MessageExchagneListener MessageExchangeListener
