public class DefaultListableBeanFactory
extends AbstractAutowireCapableBeanFactory
implements ConfigurableListableBeanFactory, BeanDefinitionRegistry, Serializable

Spring's default implementation of the ConfigurableListableBeanFactory and BeanDefinitionRegistry interfaces: a full-fledged bean factory based on bean definition metadata, extensible through post-processors.

Typical usage is registering all bean definitions first (possibly read from a bean definition file), before accessing beans. Bean lookup by name is therefore an inexpensive operation in a local bean definition table, operating on pre-resolved bean definition metadata objects.

Note that readers for specific bean definition formats are typically implemented separately rather than as bean factory subclasses: see for example XmlBeanDefinitionReader.

For an alternative implementation of the ListableBeanFactory interface, have a look at StaticListableBeanFactory, which manages existing bean instances rather than creating new ones based on bean definitions.

Constructor Details

DefaultListableBeanFactory

public DefaultListableBeanFactory()

Create a new DefaultListableBeanFactory.

DefaultListableBeanFactory

public DefaultListableBeanFactory(@Nullable
 BeanFactory parentBeanFactory)

Create a new DefaultListableBeanFactory with the given parent.

Parameters:

parentBeanFactory - the parent BeanFactory

Method Details

setSerializationId

public void setSerializationId(@Nullable
 String serializationId)

Specify an id for serialization purposes, allowing this BeanFactory to be deserialized from this id back into the BeanFactory object, if needed.

getSerializationId

@Nullable
public String getSerializationId()

Return an id for serialization purposes, if specified, allowing this BeanFactory to be deserialized from this id back into the BeanFactory object, if needed.

Since:

4.1.2

setAllowBeanDefinitionOverriding

public void setAllowBeanDefinitionOverriding(boolean allowBeanDefinitionOverriding)

Set whether it should be allowed to override bean definitions by registering a different definition with the same name, automatically replacing the former. If not, an exception will be thrown. This also applies to overriding aliases.

Default is "true".

See Also:

• registerBeanDefinition(java.lang.String, org.springframework.beans.factory.config.BeanDefinition)

isAllowBeanDefinitionOverriding

public boolean isAllowBeanDefinitionOverriding()

Return whether it should be allowed to override bean definitions by registering a different definition with the same name, automatically replacing the former.

Since:

4.1.2

setAllowEagerClassLoading

public void setAllowEagerClassLoading(boolean allowEagerClassLoading)

Set whether the factory is allowed to eagerly load bean classes even for bean definitions that are marked as "lazy-init".

Default is "true". Turn this flag off to suppress class loading for lazy-init beans unless such a bean is explicitly requested. In particular, by-type lookups will then simply ignore bean definitions without resolved class name, instead of loading the bean classes on demand just to perform a type check.

See Also:

• AbstractBeanDefinition.setLazyInit(boolean)

isAllowEagerClassLoading

public boolean isAllowEagerClassLoading()

Return whether the factory is allowed to eagerly load bean classes even for bean definitions that are marked as "lazy-init".

Since:

4.1.2

setDependencyComparator

public void setDependencyComparator(@Nullable
 Comparator<Object> dependencyComparator)

Set a Comparator for dependency Lists and arrays.

Since:

4.0

See Also:

• OrderComparator
• AnnotationAwareOrderComparator

getDependencyComparator

@Nullable
public Comparator<Object> getDependencyComparator()

Return the dependency comparator for this BeanFactory (may be null).

Since:

4.0

setAutowireCandidateResolver

public void setAutowireCandidateResolver(AutowireCandidateResolver autowireCandidateResolver)

Set a custom autowire candidate resolver for this BeanFactory to use when deciding whether a bean definition should be considered as a candidate for autowiring.

getAutowireCandidateResolver

public AutowireCandidateResolver getAutowireCandidateResolver()

Return the autowire candidate resolver for this BeanFactory (never null).

copyConfigurationFrom

public void copyConfigurationFrom(ConfigurableBeanFactory otherFactory)

Description copied from interface: ConfigurableBeanFactory

Copy all relevant configuration from the given other factory.

Should include all standard configuration settings as well as BeanPostProcessors, Scopes, and factory-specific internal settings. Should not include any metadata of actual bean definitions, such as BeanDefinition objects and bean name aliases.

Specified by:

copyConfigurationFrom in interface ConfigurableBeanFactory

Overrides:

copyConfigurationFrom in class AbstractAutowireCapableBeanFactory

Parameters:

otherFactory - the other BeanFactory to copy from

getBean

public <T> T getBean(Class<T> requiredType)
              throws BeansException

Description copied from interface: BeanFactory

Return the bean instance that uniquely matches the given object type, if any.

This method goes into ListableBeanFactory by-type lookup territory but may also be translated into a conventional by-name lookup based on the name of the given type. For more extensive retrieval operations across sets of beans, use ListableBeanFactory and/or BeanFactoryUtils.

Specified by:

getBean in interface BeanFactory

Parameters:

requiredType - type the bean must match; can be an interface or superclass

Returns:

an instance of the single bean matching the required type

Throws:

NoSuchBeanDefinitionException - if no bean of the given type was found

NoUniqueBeanDefinitionException - if more than one bean of the given type was found

BeansException - if the bean could not be created

See Also:

• ListableBeanFactory

getBean

public <T> T getBean(Class<T> requiredType,
 @Nullable
 Object... args)
              throws BeansException

Description copied from interface: BeanFactory

Return an instance, which may be shared or independent, of the specified bean.

Allows for specifying explicit constructor arguments / factory method arguments, overriding the specified default arguments (if any) in the bean definition.

This method goes into ListableBeanFactory by-type lookup territory but may also be translated into a conventional by-name lookup based on the name of the given type. For more extensive retrieval operations across sets of beans, use ListableBeanFactory and/or BeanFactoryUtils.

Specified by:

getBean in interface BeanFactory

Parameters:

requiredType - type the bean must match; can be an interface or superclass

args - arguments to use when creating a bean instance using explicit arguments (only applied when creating a new instance as opposed to retrieving an existing one)

Returns:

an instance of the bean

Throws:

NoSuchBeanDefinitionException - if there is no such bean definition

BeanDefinitionStoreException - if arguments have been given but the affected bean isn't a prototype

BeansException - if the bean could not be created

getBeanProvider

public <T> ObjectProvider<T> getBeanProvider(Class<T> requiredType)

Description copied from interface: BeanFactory

Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options.

For matching a generic type, consider BeanFactory.getBeanProvider(ResolvableType).

Specified by:

getBeanProvider in interface BeanFactory

Parameters:

requiredType - type the bean must match; can be an interface or superclass

Returns:

a corresponding provider handle

See Also:

• BeanFactory.getBeanProvider(ResolvableType)

getBeanProvider

public <T> ObjectProvider<T> getBeanProvider(ResolvableType requiredType)

Description copied from interface: BeanFactory

Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options. This variant allows for specifying a generic type to match, similar to reflective injection points with generic type declarations in method/constructor parameters.

Note that collections of beans are not supported here, in contrast to reflective injection points. For programmatically retrieving a list of beans matching a specific type, specify the actual bean type as an argument here and subsequently use ObjectProvider.orderedStream() or its lazy streaming/iteration options.

Also, generics matching is strict here, as per the Java assignment rules. For lenient fallback matching with unchecked semantics (similar to the ´unchecked´ Java compiler warning), consider calling BeanFactory.getBeanProvider(Class) with the raw type as a second step if no full generic match is available with this variant.

Specified by:

getBeanProvider in interface BeanFactory

Parameters:

requiredType - type the bean must match; can be a generic type declaration

Returns:

a corresponding provider handle

See Also:

• ObjectProvider.iterator()
• ObjectProvider.stream()
• ObjectProvider.orderedStream()

containsBeanDefinition

public boolean containsBeanDefinition(String beanName)

Description copied from class: AbstractBeanFactory

Check if this bean factory contains a bean definition with the given name. Does not consider any hierarchy this factory may participate in. Invoked by containsBean when no cached singleton instance is found.

Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.

Specified by:

containsBeanDefinition in interface BeanDefinitionRegistry

Specified by:

containsBeanDefinition in interface ListableBeanFactory

Specified by:

containsBeanDefinition in class AbstractBeanFactory

Parameters:

beanName - the name of the bean to look for

Returns:

if this bean factory contains a bean definition with the given name

See Also:

• AbstractBeanFactory.containsBean(java.lang.String)
• ListableBeanFactory.containsBeanDefinition(java.lang.String)

getBeanDefinitionCount

public int getBeanDefinitionCount()

Description copied from interface: ListableBeanFactory

Return the number of beans defined in the factory.

Does not consider any hierarchy this factory may participate in, and ignores any singleton beans that have been registered by other means than bean definitions.

Specified by:

getBeanDefinitionCount in interface BeanDefinitionRegistry

Specified by:

getBeanDefinitionCount in interface ListableBeanFactory

Returns:

the number of beans defined in the factory

getBeanDefinitionNames

public String[] getBeanDefinitionNames()

Description copied from interface: ListableBeanFactory

Return the names of all beans defined in this factory.

Does not consider any hierarchy this factory may participate in, and ignores any singleton beans that have been registered by other means than bean definitions.

Specified by:

getBeanDefinitionNames in interface BeanDefinitionRegistry

Specified by:

getBeanDefinitionNames in interface ListableBeanFactory

Returns:

the names of all beans defined in this factory, or an empty array if none defined

public <T> ObjectProvider<T> getBeanProvider(Class<T> requiredType,
 boolean allowEagerInit)

Description copied from interface: ListableBeanFactory

Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options.

Specified by:

getBeanProvider in interface ListableBeanFactory

Parameters:

requiredType - type the bean must match; can be an interface or superclass

allowEagerInit - whether stream-based access may initialize lazy-init singletons and objects created by FactoryBeans (or by factory methods with a "factory-bean" reference) for the type check

Returns:

a corresponding provider handle

See Also:

• ListableBeanFactory.getBeanProvider(ResolvableType, boolean)
• BeanFactory.getBeanProvider(Class)
• ListableBeanFactory.getBeansOfType(Class, boolean, boolean)
• ListableBeanFactory.getBeanNamesForType(Class, boolean, boolean)

getBeanProvider

public <T> ObjectProvider<T> getBeanProvider(ResolvableType requiredType,
 boolean allowEagerInit)

Description copied from interface: ListableBeanFactory

Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options.

Specified by:

getBeanProvider in interface ListableBeanFactory

Parameters:

requiredType - type the bean must match; can be a generic type declaration. Note that collection types are not supported here, in contrast to reflective injection points. For programmatically retrieving a list of beans matching a specific type, specify the actual bean type as an argument here and subsequently use ObjectProvider.orderedStream() or its lazy streaming/iteration options.

allowEagerInit - whether stream-based access may initialize lazy-init singletons and objects created by FactoryBeans (or by factory methods with a "factory-bean" reference) for the type check

Returns:

a corresponding provider handle

See Also:

• BeanFactory.getBeanProvider(ResolvableType)
• ObjectProvider.iterator()
• ObjectProvider.stream()
• ObjectProvider.orderedStream()
• ListableBeanFactory.getBeanNamesForType(ResolvableType, boolean, boolean)

getBeanNamesForType

public String[] getBeanNamesForType(ResolvableType type)

Description copied from interface: ListableBeanFactory

Return the names of beans matching the given type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

This version of getBeanNamesForType matches all kinds of beans, be it singletons, prototypes, or FactoryBeans. In most implementations, the result will be the same as for getBeanNamesForType(type, true, true).

Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

Specified by:

getBeanNamesForType in interface ListableBeanFactory

Parameters:

type - the generically typed class or interface to match

Returns:

the names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

See Also:

• BeanFactory.isTypeMatch(String, ResolvableType)
• FactoryBean.getObjectType()
• BeanFactoryUtils.beanNamesForTypeIncludingAncestors(ListableBeanFactory, ResolvableType)

getBeanNamesForType

public String[] getBeanNamesForType(ResolvableType type,
 boolean includeNonSingletons,
 boolean allowEagerInit)

Description copied from interface: ListableBeanFactory

Return the names of beans matching the given type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

Does consider objects created by FactoryBeans if the "allowEagerInit" flag is set, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type. If "allowEagerInit" is not set, only raw FactoryBeans will be checked (which doesn't require initialization of each FactoryBean).

Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

Specified by:

getBeanNamesForType in interface ListableBeanFactory

Parameters:

type - the generically typed class or interface 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 names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

See Also:

• FactoryBean.getObjectType()
• BeanFactoryUtils.beanNamesForTypeIncludingAncestors(ListableBeanFactory, ResolvableType, boolean, boolean)

getBeanNamesForType

NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

This version of getBeanNamesForType matches all kinds of beans, be it singletons, prototypes, or FactoryBeans. In most implementations, the result will be the same as for getBeanNamesForType(type, true, true).

Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

Specified by:

getBeanNamesForType in interface ListableBeanFactory

Parameters:

type - the class or interface to match, or null for all bean names

Returns:

the names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

• BeanFactoryUtils.beanNamesForTypeIncludingAncestors(ListableBeanFactory, Class)

getBeanNamesForType

public String[] getBeanNamesForType(@Nullable
 Class<?> type,
 boolean includeNonSingletons,
 boolean allowEagerInit)

Description copied from interface: ListableBeanFactory

Return the names of beans matching the given type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

Does consider objects created by FactoryBeans if the "allowEagerInit" flag is set, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type. If "allowEagerInit" is not set, only raw FactoryBeans will be checked (which doesn't require initialization of each FactoryBean).

Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

Specified by:

getBeanNamesForType in interface ListableBeanFactory

Parameters:

type - the class or interface to match, or null for all bean names

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 names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

registerResolvableDependency

public void registerResolvableDependency(Class<?> dependencyType,
 @Nullable
 Object autowiredValue)

Description copied from interface: ConfigurableListableBeanFactory

Register a special dependency type with corresponding autowired value.

This is intended for factory/context references that are supposed to be autowirable but are not defined as beans in the factory: e.g. a dependency of type ApplicationContext resolved to the ApplicationContext instance that the bean is living in.

Note: There are no such default types registered in a plain BeanFactory, not even for the BeanFactory interface itself.

Specified by:

registerResolvableDependency in interface ConfigurableListableBeanFactory

Parameters:

dependencyType - the dependency type to register. This will typically be a base interface such as BeanFactory, with extensions of it resolved as well if declared as an autowiring dependency (e.g. ListableBeanFactory), as long as the given value actually implements the extended interface.

autowiredValue - the corresponding autowired value. This may also be an implementation of the ObjectFactory interface, which allows for lazy resolution of the actual target value.

isAutowireCandidate

public boolean isAutowireCandidate(String beanName,
 DependencyDescriptor descriptor)
                            throws NoSuchBeanDefinitionException

Determine whether the specified bean qualifies as an autowire candidate, to be injected into other beans which declare a dependency of matching type.

This method checks ancestor factories as well.

Specified by:

isAutowireCandidate in interface ConfigurableListableBeanFactory

Parameters:

beanName - the name of the bean to check

descriptor - the descriptor of the dependency to resolve

Returns:

whether the bean should be considered as autowire candidate

Throws:

NoSuchBeanDefinitionException - if there is no bean with the given name

isAutowireCandidate

protected boolean isAutowireCandidate(String beanName,
 DependencyDescriptor descriptor,
 AutowireCandidateResolver resolver)
                               throws NoSuchBeanDefinitionException

Determine whether the specified bean definition qualifies as an autowire candidate, to be injected into other beans which declare a dependency of matching type.

Parameters:

beanName - the name of the bean definition to check

descriptor - the descriptor of the dependency to resolve

resolver - the AutowireCandidateResolver to use for the actual resolution algorithm

Returns:

whether the bean should be considered as autowire candidate

Throws:

NoSuchBeanDefinitionException

Determine whether the specified bean definition qualifies as an autowire candidate, to be injected into other beans which declare a dependency of matching type.

Parameters:

beanName - the name of the bean definition to check

mbd - the merged bean definition to check

descriptor - the descriptor of the dependency to resolve

resolver - the AutowireCandidateResolver to use for the actual resolution algorithm

Returns:

whether the bean should be considered as autowire candidate

getBeanDefinition

public BeanDefinition getBeanDefinition(String beanName)
                                 throws NoSuchBeanDefinitionException

Description copied from class: AbstractBeanFactory

Return the bean definition for the given bean name. Subclasses should normally implement caching, as this method is invoked by this class every time bean definition metadata is needed.

Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.

Specified by:

getBeanDefinition in interface BeanDefinitionRegistry

Specified by:

getBeanDefinition in interface ConfigurableListableBeanFactory

Specified by:

getBeanDefinition in class AbstractBeanFactory

Parameters:

beanName - the name of the bean to find a definition for

Returns:

the BeanDefinition for this prototype name (never null)

Throws:

NoSuchBeanDefinitionException - if the bean definition cannot be resolved

See Also:

• RootBeanDefinition
• ChildBeanDefinition
• ConfigurableListableBeanFactory.getBeanDefinition(java.lang.String)

getBeanNamesIterator

public Iterator<String> getBeanNamesIterator()

Description copied from interface: ConfigurableListableBeanFactory

Return a unified view over all bean names managed by this factory.

Includes bean definition names as well as names of manually registered singleton instances, with bean definition names consistently coming first, analogous to how type/annotation specific retrieval of bean names works.

Specified by:

getBeanNamesIterator in interface ConfigurableListableBeanFactory

Returns:

the composite iterator for the bean names view

registerSingleton

public void registerSingleton(String beanName,
 Object singletonObject)
                       throws IllegalStateException

Description copied from interface: SingletonBeanRegistry

Register the given existing object as singleton in the bean registry, under the given bean name.

The given instance is supposed to be fully initialized; the registry will not perform any initialization callbacks (in particular, it won't call InitializingBean's afterPropertiesSet method). The given instance will not receive any destruction callbacks (like DisposableBean's destroy method) either.

When running within a full BeanFactory: Register a bean definition instead of an existing instance if your bean is supposed to receive initialization and/or destruction callbacks.

Typically invoked during registry configuration, but can also be used for runtime registration of singletons. As a consequence, a registry implementation should synchronize singleton access; it will have to do this anyway if it supports a BeanFactory's lazy initialization of singletons.

Specified by:

registerSingleton in interface SingletonBeanRegistry

Overrides:

registerSingleton in class DefaultSingletonBeanRegistry

Parameters:

beanName - the name of the bean

singletonObject - the existing singleton object

Throws:

IllegalStateException
