cloneIfNecessary

public AutowireCandidateResolver cloneIfNecessary()

This implementation returns this as-is.

Specified by:

cloneIfNecessary in interface AutowireCandidateResolver

resolveAutowireCandidates

public static <T> Map<String,T> resolveAutowireCandidates(ConfigurableListableBeanFactory lbf,
 Class<T> type)

Resolve a map of all beans of the given type, also picking up beans defined in ancestor bean factories, with the specific condition that each bean actually has autowire candidate status. This matches simple injection point resolution as implemented by this AutowireCandidateResolver strategy, including beans which are not marked as default candidates but excluding beans which are not even marked as autowire candidates.

Parameters:

lbf - the bean factory

type - the type of bean to match

Returns:

the Map of matching bean instances, or an empty Map if none

Throws:

BeansException - if a bean could not be created

Since:

6.2.3

resolveAutowireCandidates

public static <T> Map<String,T> resolveAutowireCandidates(ConfigurableListableBeanFactory lbf,
 Class<T> type,
 boolean includeNonSingletons,
 boolean allowEagerInit)

Resolve a map of all beans of the given type, also picking up beans defined in ancestor bean factories, with the specific condition that each bean actually has autowire candidate status. This matches simple injection point resolution as implemented by this AutowireCandidateResolver strategy, including beans which are not marked as default candidates but excluding beans which are not even marked as autowire candidates.

Parameters:

lbf - the bean factory

type - the type of bean to match

includeNonSingletons - whether to include prototype or scoped beans too or just singletons (also applies to FactoryBeans)

allowEagerInit - whether to initialize lazy-init singletons and objects created by FactoryBeans (or by factory methods with a "factory-bean" reference) for the type check. Note that FactoryBeans need to be eagerly initialized to determine their type: So be aware that passing in "true" for this flag will initialize FactoryBeans and "factory-bean" references.

Returns:

the Map of matching bean instances, or an empty Map if none

Throws:

BeansException - if a bean could not be created

Since:

6.2.5
