public abstract class AbstractBeanFactory extends FactoryBeanRegistrySupport implements ConfigurableBeanFactory
BeanFactory
implementations, providing the full capabilities of the
ConfigurableBeanFactory
SPI.
Does not assume a listable bean factory: can therefore also be used
as base class for bean factory implementations which obtain bean definitions
from some backend resource (where bean definition access is an expensive operation).
This class provides a singleton cache (through its base class
DefaultSingletonBeanRegistry
,
singleton/prototype determination, FactoryBean
handling, aliases, bean definition merging for child bean definitions,
and bean destruction (DisposableBean
interface, custom destroy methods). Furthermore, it can manage a bean factory
hierarchy (delegating to the parent in case of an unknown bean), through implementing
the HierarchicalBeanFactory
interface.
The main template methods to be implemented by subclasses are
getBeanDefinition(java.lang.String)
and createBean(java.lang.String, org.springframework.beans.factory.support.RootBeanDefinition, java.lang.Object[])
, retrieving a bean definition
for a given bean name and creating a bean instance for a given bean definition,
respectively. Default implementations of those operations can be found in
DefaultListableBeanFactory
and AbstractAutowireCapableBeanFactory
.

BeanFactory
This method allows a Spring BeanFactory to be used as a replacement for the Singleton or Prototype design pattern. Callers may retain references to returned objects in the case of Singleton beans.
Translates aliases back to the corresponding canonical bean name. Will ask the parent factory if the bean cannot be found in this factory instance.

BeanFactory
Behaves the same as BeanFactory.getBean(String)
, but provides a measure of type
safety by throwing a BeanNotOfRequiredTypeException if the bean is not of the
required type. This means that ClassCastException can't be thrown on casting
the result correctly, as can happen with BeanFactory.getBean(String)
.
Translates aliases back to the corresponding canonical bean name. Will ask the parent factory if the bean cannot be found in this factory instance.

BeanFactory
If the given name is an alias, it will be translated back to the corresponding canonical bean name.
If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance.
If a bean definition or singleton instance matching the given name is found,
this method will return true
whether the named bean definition is concrete
or abstract, lazy or eager, in scope or not. Therefore, note that a true
return value from this method does not necessarily indicate that BeanFactory.getBean(java.lang.String)
will be able to obtain an instance for the same name.

Does not need to handle FactoryBeans specifically, since it is only
supposed to operate on the raw bean type.
This implementation is simplistic in that it is not able to handle factory methods and InstantiationAwareBeanPostProcessors. It only predicts the bean type correctly for a standard bean. To be overridden in subclasses, applying more sophisticated type detection.

The default implementation creates the FactoryBean via getBean
to call its getObjectType
method. Subclasses are encouraged to optimize
this, typically by just instantiating the FactoryBean but not populating it yet,
trying whether its getObjectType
method already returns a type.
If no type found, a full FactoryBean creation as performed by this implementation
should be used as fallback.

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.
