Interface ImportSelector

All Known Subinterfaces:

DeferredImportSelector

All Known Implementing Classes:

AdviceModeImportSelector, AsyncConfigurationSelector, CachingConfigurationSelector, TransactionManagementConfigurationSelector

public interface ImportSelector

Interface to be implemented by types that determine which @Configuration class(es) should be imported based on a given selection criteria, usually one or more annotation attributes.

An ImportSelector may implement any of the following Aware interfaces, and their respective methods will be called prior to selectImports(org.springframework.core.type.AnnotationMetadata):

• EnvironmentAware
• BeanFactoryAware
• BeanClassLoaderAware
• ResourceLoaderAware

Alternatively, the class may provide a single constructor with one or more of the following supported parameter types:

• Environment
• BeanFactory
• ClassLoader
• ResourceLoader

ImportSelector implementations are usually processed in the same way as regular @Import annotations, however, it is also possible to defer selection of imports until all @Configuration classes have been processed (see DeferredImportSelector for details).
