Class ConfigurationClassBeanDefinitionReader

java.lang.Object
  org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader

 class ConfigurationClassBeanDefinitionReader
extends java.lang.Object

Reads a given fully-populated configuration model, registering bean definitions with the given BeanDefinitionRegistry based on its contents.

This class was modeled after the BeanDefinitionReader hierarchy, but does not implement/extend any of its artifacts as a configuration model is not a Resource.

Since:

3.0

Parameters:

problemReporter -

metadataReaderFactory -

Method Detail

loadBeanDefinitions

public void loadBeanDefinitions(java.util.Set<ConfigurationClass> configurationModel)

Reads configurationModel, registering bean definitions with registry based on its contents.

loadBeanDefinitionsForConfigurationClass

private void loadBeanDefinitionsForConfigurationClass(ConfigurationClass configClass)

Reads a particular ConfigurationClass, registering bean definitions for the class itself, all its Bean methods

doLoadBeanDefinitionForConfigurationClassIfNecessary

private void doLoadBeanDefinitionForConfigurationClassIfNecessary(ConfigurationClass configClass)

Registers the Configuration class itself as a bean definition.

loadBeanDefinitionsForModelMethod

private void loadBeanDefinitionsForModelMethod(ConfigurationClassMethod method)

Reads a particular ConfigurationClassMethod, registering bean definitions with the BeanDefinitionRegistry based on its contents.

loadBeanDefinitionsFromImportedResources

private void loadBeanDefinitionsFromImportedResources(java.util.Map<java.lang.String,java.lang.Class<?>> importedResources)

checkConfigurationClassCandidate

public static boolean checkConfigurationClassCandidate(BeanDefinition beanDef,
                                                       MetadataReaderFactory metadataReaderFactory)

Check whether the given bean definition is a candidate for a configuration class, and mark it accordingly.

Parameters:

beanDef - the bean definition to check

metadataReaderFactory - the current factory in use by the caller

Returns:

whether the candidate qualifies as (any kind of) configuration class

isFullConfigurationClass

public static boolean isFullConfigurationClass(BeanDefinition beanDef)

Determine whether the given bean definition indicates a full @Configuration class.
