BootstrapApplicationListener (Spring Cloud Context 3.1.8 API)

java.lang.Object
- org.springframework.cloud.bootstrap.BootstrapApplicationListener

All Implemented Interfaces:

EventListener, org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent>, org.springframework.core.Ordered
```
public class BootstrapApplicationListener
extends Object
implements org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent>, org.springframework.core.Ordered
```
A listener that prepares a SpringApplication (e.g. populating its Environment) by delegating to ApplicationContextInitializer beans in a separate bootstrap context. The bootstrap context is a SpringApplication created from sources defined in spring.factories as BootstrapConfiguration, and initialized with external config taken from "bootstrap.properties" (or yml), instead of the normal "application.properties".
