Class DefaultListableBeanFactory
- All Implemented Interfaces:
Serializable,BeanFactory,AutowireCapableBeanFactory,ConfigurableBeanFactory,ConfigurableListableBeanFactory,SingletonBeanRegistry,HierarchicalBeanFactory,ListableBeanFactory,BeanDefinitionRegistry,AliasRegistry
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.

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

getBean
Description copied from interface:BeanFactoryReturn the bean instance that uniquely matches the given object type, if any.This method goes into
ListableBeanFactoryby-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, useListableBeanFactoryand/orBeanFactoryUtils.- Specified by:
getBeanin interfaceBeanFactory- 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 foundNoUniqueBeanDefinitionException- if more than one bean of the given type was foundBeansException- if the bean could not be created- See Also:
-
getBean
Description copied from interface:BeanFactoryReturn 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
ListableBeanFactoryby-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, useListableBeanFactoryand/orBeanFactoryUtils.- Specified by:
getBeanin interfaceBeanFactory- Parameters:
requiredType- type the bean must match; can be an interface or superclassargs- 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 definitionBeanDefinitionStoreException- if arguments have been given but the affected bean isn't a prototypeBeansException- if the bean could not be created
-
getBeanProvider
Description copied from interface:BeanFactoryReturn 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:
getBeanProviderin interfaceBeanFactory- Parameters:
requiredType- type the bean must match; can be an interface or superclass- Returns:
- a corresponding provider handle
- See Also:
-
getBeanProvider
Description copied from interface:BeanFactoryReturn 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 isavailablewith this variant.- Specified by:
getBeanProviderin interfaceBeanFactory- Parameters:
requiredType- type the bean must match; can be a generic type declaration- Returns:
- a corresponding provider handle
- See Also:
-
containsBeanDefinition
Description copied from class:AbstractBeanFactoryCheck if this bean factory contains a bean definition with the given name. Does not consider any hierarchy this factory may participate in. Invoked bycontainsBeanwhen 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:
containsBeanDefinitionin interfaceBeanDefinitionRegistry- Specified by:

getBeanNamesForType
Description copied from interface:ListableBeanFactoryReturn the names of beans matching the given type (including subclasses), judging from either bean definitions or the value ofgetObjectTypein 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'
beanNamesForTypeIncludingAncestorsto 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
getBeanNamesForTypematches all kinds of beans, be it singletons, prototypes, or FactoryBeans. In most implementations, the result will be the same as forgetBeanNamesForType(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:

registerResolvableDependency
Description copied from interface:ConfigurableListableBeanFactoryRegister 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:
registerResolvableDependencyin interfaceConfigurableListableBeanFactory- 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 theObjectFactoryinterface, which allows for lazy resolution of the actual target value.

getBeanDefinition
Description copied from class:AbstractBeanFactoryReturn 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.

registerSingleton
Description copied from interface:SingletonBeanRegistryRegister 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
afterPropertiesSetmethod). The given instance will not receive any destruction callbacks (like DisposableBean'sdestroymethod) 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.
