```
public abstract class AbstractBeanFactory
extends FactoryBeanRegistrySupport
implements ConfigurableBeanFactory
```
Abstract base class for 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.

public Object getBean(String name)
               throws BeansException
```
    Description copied from interface: BeanFactory
    Return an instance, which may be shared or independent, of the specified bean.
    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.
    Specified by:
    getBean in interface BeanFactory
    Parameters:
    name - the name of the bean to retrieve
    Returns:
    an instance of the bean
    Throws:
    NoSuchBeanDefinitionException - if there is no bean with the specified name
    BeansException - if the bean could not be obtained

              throws BeansException
```
    Description copied from interface: BeanFactory
    Return an instance, which may be shared or independent, of the specified bean.
    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.
    Specified by:
    getBean in interface BeanFactory
    Parameters:
    name - the name of the bean to retrieve
    requiredType - type the bean must match. Can be an interface or superclass of the actual class, or null for any match. For example, if the value is Object.class, this method will succeed whatever the class of the returned instance.
    Returns:
    an instance of the bean
    Throws:
    NoSuchBeanDefinitionException - if there is no such bean definition
    BeanNotOfRequiredTypeException - if the bean is not of the required type
    BeansException - if the bean could not be created

    Return an instance, which may be shared or independent, of the specified bean.
    Parameters:
    name - the name of the bean to retrieve

    Returns:
    an instance of the bean
    Throws:

```
public boolean containsBean(String name)
```
    Description copied from interface: BeanFactory
    Does this bean factory contain a bean definition or externally registered singleton instance with the given name?
    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.
    Specified by:
    containsBean in interface BeanFactory
    Parameters:
    name - the name of the bean to query
    Returns:
    whether a bean with the given name is present
  - isSingleton
```
public boolean isSingleton(String name)
                    throws NoSuchBeanDefinitionException
```
    Description copied from interface: BeanFactory
    Is this bean a shared singleton? That is, will BeanFactory.getBean(java.lang.String) always return the same instance?
    Note: This method returning false does not clearly indicate independent instances. It indicates non-singleton instances, which may correspond to a scoped bean as well. Use the BeanFactory.isPrototype(java.lang.String) operation to explicitly check for independent instances.
    Translates aliases back to the corresponding canonical bean name. Will ask the parent factory if the bean cannot be found in this factory instance.
    Specified by:
    isSingleton in interface BeanFactory
    Parameters:
    name - the name of the bean to query
    Returns:
    whether this bean corresponds to a singleton instance
    Throws:
    NoSuchBeanDefinitionException - if there is no bean with the given name

                    throws NoSuchBeanDefinitionException
```
    Description copied from interface: BeanFactory
    Is this bean a prototype? That is, will BeanFactory.getBean(java.lang.String) always return independent instances?
    Note: This method returning false does not clearly indicate a singleton object. It indicates non-independent instances, which may correspond to a scoped bean as well. Use the BeanFactory.isSingleton(java.lang.String) operation to explicitly check for a shared singleton instance.
    Translates aliases back to the corresponding canonical bean name. Will ask the parent factory if the bean cannot be found in this factory instance.
    Specified by:
    isPrototype in interface BeanFactory
    Parameters:
    name - the name of the bean to query
    Returns:

    Note that this class loader will only apply to bean definitions that do not carry a resolved bean class yet. This is the case as of Spring 2.0 by default: Bean definitions only carry bean class names, to be resolved once the factory processes the bean definition.
    Specified by:
    setBeanClassLoader in interface ConfigurableBeanFactory
    Parameters:
    beanClassLoader - the class loader to use, or null to suggest the default class loader
  - getBeanClassLoader
```
public ClassLoader getBeanClassLoader()
```
    Description copied from interface: ConfigurableBeanFactory
    Return this factory's class loader for loading bean classes.
    Specified by:
    getBeanClassLoader in interface ConfigurableBeanFactory
  - setTempClassLoader
```
public void setTempClassLoader(ClassLoader tempClassLoader)
```
    Description copied from interface: ConfigurableBeanFactory
    Specify a temporary ClassLoader to use for type matching purposes. Default is none, simply using the standard bean ClassLoader.
    A temporary ClassLoader is usually just specified if load-time weaving is involved, to make sure that actual bean classes are loaded as lazily as possible. The temporary loader is then removed once the BeanFactory completes its bootstrap phase.
    Specified by:
    setTempClassLoader in interface ConfigurableBeanFactory

  - addPropertyEditorRegistrar
```
public void addPropertyEditorRegistrar(PropertyEditorRegistrar registrar)
```
    Description copied from interface: ConfigurableBeanFactory
    Add a PropertyEditorRegistrar to be applied to all bean creation processes.
    Such a registrar creates new PropertyEditor instances and registers them on the given registry, fresh for each bean creation attempt. This avoids the need for synchronization on custom editors; hence, it is generally preferable to use this method instead of ConfigurableBeanFactory.registerCustomEditor(java.lang.Class<?>, java.lang.Class<? extends java.beans.PropertyEditor>).
    Specified by:
    addPropertyEditorRegistrar in interface ConfigurableBeanFactory
    Parameters:

```
    Description copied from interface: ConfigurableBeanFactory
    Register the given custom property editor for all properties of the given type. To be invoked during factory configuration.
    Note that this method will register a shared custom editor instance; access to that instance will be synchronized for thread-safety. It is generally preferable to use ConfigurableBeanFactory.addPropertyEditorRegistrar(org.springframework.beans.PropertyEditorRegistrar) instead of this method, to avoid for the need for synchronization on custom editors.
    Specified by:
    registerCustomEditor in interface ConfigurableBeanFactory
    Parameters:
    requiredType - type of the property
    propertyEditorClass - the PropertyEditor class to register

                                   Class<?>... typesToMatch)
```
    Predict the eventual bean type (of the processed bean instance) for the specified bean. Called by getType(java.lang.String) and isTypeMatch(java.lang.String, org.springframework.core.ResolvableType). 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.
    Parameters:
    beanName - the name of the bean
    mbd - the merged bean definition to determine the type for
    typesToMatch - the types to match in case of internal type matching purposes (also signals that the returned Class will never be exposed to application code)

  - isFactoryBean
```
protected boolean isFactoryBean(String beanName,
                                RootBeanDefinition mbd)

    Check whether the given bean is defined as a FactoryBean.
    Parameters:
    beanName - the name of the bean
    mbd - the corresponding bean definition
  - getTypeForFactoryBean
```
protected Class<?> getTypeForFactoryBean(String beanName,
                                         RootBeanDefinition mbd)
```
    Determine the bean type for the given FactoryBean definition, as far as possible. Only called if there is no singleton instance registered for the target bean already.
    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.
    Parameters:
    beanName - the name of the bean
    mbd - the merged bean definition for the bean
    Returns:
    the type for the bean if determinable, or null otherwise
    See Also:
    FactoryBean.getObjectType(), getBean(String)
  - markBeanAsCreated
```
protected void markBeanAsCreated(String beanName)

    Parameters:
    beanName - the name of the bean
  - cleanupAfterBeanCreationFailure
```
protected void cleanupAfterBeanCreationFailure(String beanName)
```
    Perform appropriate cleanup of cached metadata after bean creation failed.

```
    Determine whether the specified bean is eligible for having its bean definition metadata cached.
    Parameters:
    beanName - the name of the bean
    Returns:
    true if the bean's metadata may be cached at this point already
  - removeSingletonIfCreatedForTypeCheckOnly
```
protected boolean removeSingletonIfCreatedForTypeCheckOnly(String beanName)
```
    Remove the singleton instance (if any) for the given bean name, but only if it hasn't been used for other purposes than type checking.
    Parameters:
    beanName - the name of the bean
    Returns:
    true if actually removed, false otherwise
  - hasBeanCreationStarted
```
protected boolean hasBeanCreationStarted()
```
    Check whether this factory's bean creation phase already started, i.e. whether any bean has been marked as created in the meantime.

    name - name that may include factory dereference prefix
    beanName - the canonical bean name
    mbd - the merged bean definition
    Returns:
    the object to expose for the bean
  - isBeanNameInUse
```
public boolean isBeanNameInUse(String beanName)
```
    Determine whether the given bean name is already in use within this factory, i.e. whether there is a local bean or alias registered under this name or an inner bean created with this name.
    Parameters:
    beanName - the name to check
  - requiresDestruction
```
protected boolean requiresDestruction(Object bean,
                                      RootBeanDefinition mbd)
```
    Determine whether the given bean requires destruction on shutdown.
    The default implementation checks the DisposableBean interface as well as a specified destroy method and registered DestructionAwareBeanPostProcessors.
    Parameters:
    bean - the bean instance to check
    mbd - the corresponding bean definition
    See Also:
    DisposableBean, AbstractBeanDefinition.getDestroyMethodName(), DestructionAwareBeanPostProcessor
  - registerDisposableBeanIfNecessary
```
protected void registerDisposableBeanIfNecessary(String beanName,
                                                 Object bean,
                                                 RootBeanDefinition mbd)
```
    Add the given bean to the list of disposable beans in this factory, registering its DisposableBean interface and/or the given destroy method to be called on factory shutdown (if applicable). Only applies to singletons.
    Parameters:
    beanName - the name of the bean
    bean - the bean instance
    mbd - the bean definition for the bean
    See Also:
    AbstractBeanDefinition.isSingleton(), AbstractBeanDefinition.getDependsOn(), DefaultSingletonBeanRegistry.registerDisposableBean(java.lang.String, org.springframework.beans.factory.DisposableBean), DefaultSingletonBeanRegistry.registerDependentBean(java.lang.String, java.lang.String)
  - containsBeanDefinition
```
protected abstract boolean containsBeanDefinition(String beanName)
```
    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.
    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:
    containsBean(java.lang.String), ListableBeanFactory.containsBeanDefinition(java.lang.String)
  - getBeanDefinition
```
protected abstract BeanDefinition getBeanDefinition(String beanName)
                                             throws BeansException
```
    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.

    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
    BeansException - in case of errors

                                     Object[] args)
                              throws BeanCreationException
```
    Create a bean instance for the given merged bean definition (and arguments). The bean definition will already have been merged with the parent definition in case of a child definition.
    All bean retrieval methods delegate to this method for actual bean creation.
    Parameters:
    beanName - the name of the bean
    mbd - the merged bean definition for the bean
    args - explicit arguments to use for constructor or factory method invocation
    Returns:
    a new instance of the bean
    Throws:
    BeanCreationException - if the bean could not be created

Constructor	Description
`AbstractBeanFactory()`	Create a new AbstractBeanFactory.
`AbstractBeanFactory(BeanFactory parentBeanFactory)`	Create a new AbstractBeanFactory with the given parent.
