Class GenericTypeAwareAutowireCandidateResolver

java.lang.Object

org.springframework.beans.factory.support.SimpleAutowireCandidateResolver

org.springframework.beans.factory.support.GenericTypeAwareAutowireCandidateResolver

All Implemented Interfaces:

Cloneable, Aware, BeanFactoryAware, AutowireCandidateResolver

Direct Known Subclasses:

QualifierAnnotationAutowireCandidateResolver

public class GenericTypeAwareAutowireCandidateResolver
extends SimpleAutowireCandidateResolver
implements BeanFactoryAware, Cloneable

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 Details

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.

See Also:

• BeanInitializationException

getBeanFactory

@Nullable
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.

The default implementation checks BeanDefinition.isAutowireCandidate().

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

See Also:

• BeanDefinition.isAutowireCandidate()

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

@Nullable
protected RootBeanDefinition getResolvedDecoratedDefinition(RootBeanDefinition rbd)

getReturnTypeForFactoryMethod

@Nullable
protected ResolvableType getReturnTypeForFactoryMethod(RootBeanDefinition rbd,
 DependencyDescriptor descriptor)

cloneIfNecessary

public AutowireCandidateResolver cloneIfNecessary()

This implementation clones all instance fields through standard Cloneable support, allowing for subsequent reconfiguration of the cloned instance through a fresh setBeanFactory(org.springframework.beans.factory.BeanFactory) call.

Specified by:

cloneIfNecessary in interface AutowireCandidateResolver

Overrides:

cloneIfNecessary in class SimpleAutowireCandidateResolver
