Interface DeferredImportSelector

All Superinterfaces:

ImportSelector

public interface DeferredImportSelector
extends ImportSelector

A variation of ImportSelector that runs after all @Configuration beans have been processed. This type of selector can be particularly useful when the selected imports are @Conditional.

Implementations can also extend the Ordered interface or use the Order annotation to indicate a precedence against other DeferredImportSelectors.

Implementations may also provide an import group which can provide additional sorting and filtering logic across different selectors.
