Method Detail

selectImports

public String[] selectImports(AnnotationMetadata metadata)

Specified by:

selectImports in interface ImportSelector

getAttributes

protected AnnotationAttributes getAttributes(AnnotationMetadata metadata)

Return the appropriate AnnotationAttributes from the AnnotationMetadata. By default this method will return attributes for getAnnotationClass().

Parameters:

metadata - the annotation metadata

Returns:

annotation attributes

getAnnotationClass

protected Class<?> getAnnotationClass()

Return the source annotation class used by the selector.

Returns:

the annotation class

getCandidateConfigurations

protected List<String> getCandidateConfigurations(AnnotationMetadata metadata,
                                                  AnnotationAttributes attributes)

Return the auto-configuration class names that should be considered. By default this method will load candidates using SpringFactoriesLoader with getSpringFactoriesLoaderFactoryClass().

Parameters:

metadata - the source metadata

attributes - the annotation attributes

Returns:

a list of candidate configurations

getSpringFactoriesLoaderFactoryClass

protected Class<?> getSpringFactoriesLoaderFactoryClass()

Return the class used by SpringFactoriesLoader to load configuration candidates.

Returns:

the factory class

getExclusions

protected Set<String> getExclusions(AnnotationMetadata metadata,
                                    AnnotationAttributes attributes)

Return any exclusions that limit the candidate configurations.

Parameters:

metadata - the source metadata

attributes - the annotation attributes

Returns:

exclusions or an empty set
