Class GenericTypeAwareAutowireCandidateResolver

java.lang.Object

org.springframework.beans.factory.support.SimpleAutowireCandidateResolver

org.springframework.beans.factory.support.GenericTypeAwareAutowireCandidateResolver

All Implemented Interfaces:

Aware, BeanFactoryAware, AutowireCandidateResolver

Direct Known Subclasses:

QualifierAnnotationAutowireCandidateResolver

public class GenericTypeAwareAutowireCandidateResolver
extends SimpleAutowireCandidateResolver
implements BeanFactoryAware

Basic AutowireCandidateResolver that performs a full generic type match with the candidate's type if the dependency is declared as a generic type (e.g. Repository<Customer>).

This is the base class for QualifierAnnotationAutowireCandidateResolver, providing an implementation all non-annotation-based resolution steps at this level.

Since:

4.0

Method Detail

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Description copied from interface: BeanFactoryAware

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

BeanInitializationException

getBeanFactory

protected final BeanFactory getBeanFactory()

isAutowireCandidate

public boolean isAutowireCandidate(BeanDefinitionHolder bdHolder,
                                   DependencyDescriptor descriptor)

Description copied from interface: AutowireCandidateResolver

Determine whether the given bean definition qualifies as an autowire candidate for the given dependency.

Specified by:

isAutowireCandidate in interface AutowireCandidateResolver

Overrides:

isAutowireCandidate in class SimpleAutowireCandidateResolver

Parameters:

bdHolder - the bean definition including bean name and aliases

descriptor - the descriptor for the target method parameter or field

Returns:

whether the bean definition qualifies as autowire candidate

checkGenericTypeMatch

protected boolean checkGenericTypeMatch(BeanDefinitionHolder bdHolder,
                                        DependencyDescriptor descriptor)

Match the given dependency type with its generic type information against the given candidate bean definition.

getResolvedDecoratedDefinition
