Class RepositoryConfigurationExtensionSupport

java.lang.Object

org.springframework.data.repository.config.RepositoryConfigurationExtensionSupport

All Implemented Interfaces:

RepositoryConfigurationExtension

public abstract class RepositoryConfigurationExtensionSupport
extends Object
implements RepositoryConfigurationExtension

Base implementation of RepositoryConfigurationExtension to ease the implementation of the interface. Will default the default named query location based on a module prefix provided by implementors (see getModulePrefix()). Stubs out the post-processing methods as they might not be needed by default.

getIdentifyingAnnotations

protected Collection<Class<? extends Annotation>> getIdentifyingAnnotations()

Returns:

getConfigurationInspectionClassLoader

@Nullable
protected ClassLoader getConfigurationInspectionClassLoader(ResourceLoader loader)

Returns the ClassLoader to load repository interfaces for configuration inspection. Subclasses may override this method to provide a customized class loader.

Parameters:

registerWithSourceAndGeneratedBeanName

public static String registerWithSourceAndGeneratedBeanName(AbstractBeanDefinition bean,
                                                            BeanDefinitionRegistry registry,
                                                            Object source)

Sets the given source on the given AbstractBeanDefinition and registers it inside the given BeanDefinitionRegistry. For BeanDefinitions to be registered once-and-only-once for all configuration elements (annotation or XML), prefer calling registerIfNotAlreadyRegistered(Supplier, BeanDefinitionRegistry, String, Object) with a dedicated bean name to avoid the bead definition being registered multiple times.

Parameters:

bean - must not be null.

registry - must not be null.

source - must not be null.

Returns:

the bean name generated for the given BeanDefinition

registerIfNotAlreadyRegistered

public static void registerIfNotAlreadyRegistered(Supplier<AbstractBeanDefinition> supplier,
                                                  BeanDefinitionRegistry registry,
                                                  String beanName,
                                                  Object source)

Registers the AbstractBeanDefinition produced by the given Supplier with the given registry with the given bean name unless the registry already contains a bean with that name.

Parameters:

supplier - must not be null.

registry - must not be null.

beanName - must not be null or empty.

source - must not be null.

Since:

2.1

registerLazyIfNotAlreadyRegistered

public static void registerLazyIfNotAlreadyRegistered(Supplier<AbstractBeanDefinition> supplier,
                                                      BeanDefinitionRegistry registry,
                                                      String beanName,
                                                      Object source)

Registers the AbstractBeanDefinition produced by the given Supplier as lazy bean definition with the given registry with the given bean name unless the registry already contains a bean with that name.

Parameters:

supplier - must not be null.

registry - must not be null.

beanName - must not be null or empty.

source - must not be null.

Since:

2.1

hasBean

public static boolean hasBean(Class<?> type,
                              BeanDefinitionRegistry registry)

Returns whether the given BeanDefinitionRegistry already contains a bean of the given type assuming the bean name has been auto-generated.

Parameters:

type -

registry -

Returns:

getRepositoryConfiguration

protected <T extends RepositoryConfigurationSource> RepositoryConfiguration<T> getRepositoryConfiguration(BeanDefinition definition,
                                                                                                          T configSource)

Creates a actual RepositoryConfiguration instance for the given RepositoryConfigurationSource and interface name. Defaults to the DefaultRepositoryConfiguration but allows sub-classes to override this to customize the behavior.

Parameters:

definition - will never be null or empty.

configSource - will never be null.

Returns:

isStrictRepositoryCandidate

protected boolean isStrictRepositoryCandidate(RepositoryMetadata metadata)

Returns whether the given repository metadata is a candidate for bean definition creation in the strict repository detection mode. The default implementation inspects the domain type managed for a set of well-known annotations (see getIdentifyingAnnotations()). If none of them is found, the candidate is discarded. Implementations should make sure, the only return true if they're really sure the interface handed to the method is really a store interface.

Parameters:

metadata -

Returns:

Since:

1.9

useRepositoryConfiguration

protected boolean useRepositoryConfiguration(RepositoryMetadata metadata)

Return whether to use the configuration for the repository with the given metadata. Defaults to true and InvalidDataAccessApiUsageException for reactive repositories. Must be overridden by store modules that wish to provide reactive repositories.

Parameters:

metadata - will never be null.

Returns:

Throws:

InvalidDataAccessApiUsageException - on repositories by default.
