public interface BootstrapRegistry
Environment
post-processing up to the point that the ApplicationContext is prepared.
Can be used to register instances that may be expensive to create, or need to be shared
before the ApplicationContext is available.
The registry uses Class as a key, meaning that only a single instance of a
given type can be stored.
The addCloseListener(ApplicationListener) method can be used to add a listener
that can perform actions when BootstrapContext has been closed and the
ApplicationContext is fully prepared. For example, an instance may choose to
register itself as a regular Spring bean so that it is available for the application to
use.
