ConfigurationClassPostProcessor

<init>

BeanFactoryPostProcessor used for bootstrapping processing of Configuration classes.

Registered by default when using <context:annotation-config/> or <context:component-scan/>. Otherwise, may be declared manually as with any other BeanFactoryPostProcessor.

This post processor is Ordered#HIGHEST_PRECEDENCE as it is important that any Bean methods declared in Configuration classes have their respective bean definitions registered before any other BeanFactoryPostProcessor executes.

enhanceConfigurationClasses

Post-processes a BeanFactory in search of Configuration class BeanDefinitions; any candidates are then enhanced by a ConfigurationClassEnhancer. Candidate status is determined by BeanDefinition attribute metadata.

getOrder

postProcessBeanDefinitionRegistry

Derive further bean definitions from the configuration classes in the registry.

postProcessBeanFactory

Prepare the Configuration classes for servicing bean requests at runtime by replacing them with CGLIB-enhanced subclasses.

processConfigBeanDefinitions

Build and validate a configuration model based on the registry of Configuration classes.

setBeanClassLoader

setBeanNameGenerator

Set the BeanNameGenerator to be used when triggering component scanning from Configuration classes and when registering Import'ed configuration classes. The default is a standard AnnotationBeanNameGenerator for scanned components (compatible with the default in ClassPathBeanDefinitionScanner) and a variant thereof for imported configuration classes (using unique fully-qualified class names instead of standard component overriding).

Note that this strategy does not apply to Bean methods.

This setter is typically only appropriate when configuring the post-processor as a standalone bean definition in XML, e.g. not using the dedicated AnnotationConfig* application contexts or the <context:annotation-config> element. Any bean name generator specified against the application context will take precedence over any value set here.

setEnvironment

setMetadataReaderFactory

Set the MetadataReaderFactory to use.

Default is a CachingMetadataReaderFactory for the specified bean class loader.

setProblemReporter

Set the ProblemReporter to use.

Used to register any problems detected with Configuration or Bean declarations. For instance, an @Bean method marked as final is illegal and would be reported as a problem. Defaults to FailFastProblemReporter.

setResourceLoader

setSourceExtractor

Set the SourceExtractor to use for generated bean definitions that correspond to Bean factory methods.
