Class CustomRepositoryImplementationDetector

java.lang.Object

org.springframework.data.repository.config.CustomRepositoryImplementationDetector

public class CustomRepositoryImplementationDetector
extends Object

Detects the custom implementation for a Repository instance. If configured with a ImplementationDetectionConfiguration at construction time, the necessary component scan is executed on first access, cached and its result is the filtered on every further implementation lookup according to the given ImplementationDetectionConfiguration. If none is given initially, every invocation to #detectCustomImplementation(String, String, ImplementationDetectionConfiguration) will issue a new component scan.

Constructor Detail

CustomRepositoryImplementationDetector

public CustomRepositoryImplementationDetector(Environment environment,
                                              ResourceLoader resourceLoader,
                                              ImplementationDetectionConfiguration configuration)

Creates a new CustomRepositoryImplementationDetector with the given Environment, ResourceLoader and ImplementationDetectionConfiguration. The latter will be registered for a one-time component scan for implementation candidates that will the be used and filtered in all subsequent calls to #detectCustomImplementation(RepositoryConfiguration).

Parameters:

environment - must not be null.

resourceLoader - must not be null.

configuration - must not be null.

CustomRepositoryImplementationDetector

public CustomRepositoryImplementationDetector(Environment environment,
                                              ResourceLoader resourceLoader)

Creates a new CustomRepositoryImplementationDetector with the given Environment and ResourceLoader. Calls to detectCustomImplementation(ImplementationLookupConfiguration) will issue scans for

Parameters:

environment - must not be null.

resourceLoader - must not be null.

Method Detail

detectCustomImplementation

public Optional<AbstractBeanDefinition> detectCustomImplementation(ImplementationLookupConfiguration lookup)

Tries to detect a custom implementation for a repository bean by classpath scanning.

Parameters:

lookup - must not be null.

Returns:

the AbstractBeanDefinition of the custom implementation or null if none found.
