Direct Known Subclasses:
AbstractRefreshableConfigApplicationContext
```
public abstract class AbstractRefreshableApplicationContext
extends AbstractApplicationContext
```
Base class for ApplicationContext implementations which are supposed to support multiple calls to AbstractApplicationContext.refresh(), creating a new internal bean factory instance every time. Typically (but not necessarily), such a context will be driven by a set of config locations to load bean definitions from.
The only method to be implemented by subclasses is loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory), which gets invoked on each refresh. A concrete implementation is supposed to load bean definitions into the given DefaultListableBeanFactory, typically delegating to one or more specific bean definition readers.
Note that there is a similar base class for WebApplicationContexts.AbstractRefreshableWebApplicationContext provides the same subclassing strategy, but additionally pre-implements all context functionality for web environments. There is also a pre-defined way to receive config locations for a web context.
Concrete standalone subclasses of this base class, reading in a specific bean definition format, are ClassPathXmlApplicationContext and FileSystemXmlApplicationContext, which both derive from the common AbstractXmlApplicationContext base class; AnnotationConfigApplicationContext supports @Configuration-annotated classes as a source of bean definitions.

`AbstractRefreshableApplicationContext(ApplicationContext parent)`	Create a new AbstractRefreshableApplicationContext with the given parent context.

Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected void`	`assertBeanFactoryActive()`	Overridden to turn it into a no-op: With AbstractRefreshableApplicationContext, `getBeanFactory()` serves a strong assertion for an active context anyway.
`protected void`	`cancelRefresh(BeansException ex)`	Cancel this context's refresh attempt, resetting the `active` flag after an exception got thrown.
`protected void`	`closeBeanFactory()`	Subclasses must implement this method to release their internal bean factory.
`protected DefaultListableBeanFactory`	`createBeanFactory()`	Create an internal bean factory for this context.
`protected void`	`customizeBeanFactory(DefaultListableBeanFactory beanFactory)`	Customize the internal bean factory used by this context.
`ConfigurableListableBeanFactory`	`getBeanFactory()`	Subclasses must return their internal bean factory here.
`protected boolean`	`hasBeanFactory()`	Determine whether this context currently holds a bean factory, i.e.
`protected abstract void`	`loadBeanDefinitions(DefaultListableBeanFactory beanFactory)`	Load bean definitions into the given bean factory, typically through delegating to one or more bean definition readers.
`protected void`	`refreshBeanFactory()`	This implementation performs an actual refresh of this context's underlying bean factory, shutting down the previous bean factory (if any) and initializing a fresh bean factory for the next phase of the context's lifecycle.
`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.
`void`	`setAllowCircularReferences(boolean allowCircularReferences)`	Set whether to allow circular references between beans - and automatically try to resolve them.

- Constructor Detail
  - AbstractRefreshableApplicationContext
```
public AbstractRefreshableApplicationContext()
```
    Create a new AbstractRefreshableApplicationContext with no parent.
  - AbstractRefreshableApplicationContext
```
public AbstractRefreshableApplicationContext(ApplicationContext parent)
```
    Create a new AbstractRefreshableApplicationContext with the given parent context.
    Parameters:
    parent - the parent context
- Method Detail
  - 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. Default is "true".
    See Also:
    DefaultListableBeanFactory.setAllowBeanDefinitionOverriding(boolean)
  - setAllowCircularReferences
```
public void setAllowCircularReferences(boolean allowCircularReferences)
```
    Set whether to allow circular references between beans - and automatically try to resolve them.
    Default is "true". Turn this off to throw an exception when encountering a circular reference, disallowing them completely.
    See Also:
    AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean)
  - refreshBeanFactory
```
protected final void refreshBeanFactory()
                                 throws BeansException
```
    This implementation performs an actual refresh of this context's underlying bean factory, shutting down the previous bean factory (if any) and initializing a fresh bean factory for the next phase of the context's lifecycle.
    Specified by:
    refreshBeanFactory in class AbstractApplicationContext
    Throws:
    BeansException - if initialization of the bean factory failed
  - cancelRefresh
```
protected void cancelRefresh(BeansException ex)
```
    Description copied from class: AbstractApplicationContext
    Cancel this context's refresh attempt, resetting the active flag after an exception got thrown.
    Overrides:
    cancelRefresh in class AbstractApplicationContext
    Parameters:
    ex - the exception that led to the cancellation
  - closeBeanFactory
```
protected final void closeBeanFactory()
```
    Description copied from class: AbstractApplicationContext
    Subclasses must implement this method to release their internal bean factory. This method gets invoked by AbstractApplicationContext.close() after all other shutdown work.
    Should never throw an exception but rather log shutdown failures.
    Specified by:
    closeBeanFactory in class AbstractApplicationContext
  - hasBeanFactory
```
protected final boolean hasBeanFactory()
```
    Determine whether this context currently holds a bean factory, i.e. has been refreshed at least once and not been closed yet.
  - getBeanFactory
```
public final ConfigurableListableBeanFactory getBeanFactory()
```
    Description copied from class: AbstractApplicationContext
    Subclasses must return their internal bean factory here. They should implement the lookup efficiently, so that it can be called repeatedly without a performance penalty.
    Note: Subclasses should check whether the context is still active before returning the internal bean factory. The internal factory should generally be considered unavailable once the context has been closed.
    Specified by:
    getBeanFactory in interface ConfigurableApplicationContext
    Specified by:
    getBeanFactory in class AbstractApplicationContext
    Returns:
    this application context's internal bean factory (never null)
    See Also:
    AbstractApplicationContext.refreshBeanFactory(), AbstractApplicationContext.closeBeanFactory()
  - assertBeanFactoryActive
```
protected void assertBeanFactoryActive()
```
    Overridden to turn it into a no-op: With AbstractRefreshableApplicationContext, getBeanFactory() serves a strong assertion for an active context anyway.
    Overrides:
    assertBeanFactoryActive in class AbstractApplicationContext
  - createBeanFactory
```
protected DefaultListableBeanFactory createBeanFactory()
```
    Create an internal bean factory for this context. Called for each AbstractApplicationContext.refresh() attempt.
    The default implementation creates a DefaultListableBeanFactory with the internal bean factory of this context's parent as parent bean factory. Can be overridden in subclasses, for example to customize DefaultListableBeanFactory's settings.
    Returns:
    the bean factory for this context
    See Also:
    DefaultListableBeanFactory.setAllowBeanDefinitionOverriding(boolean), DefaultListableBeanFactory.setAllowEagerClassLoading(boolean), AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean), AbstractAutowireCapableBeanFactory.setAllowRawInjectionDespiteWrapping(boolean)
  - customizeBeanFactory
```
protected void customizeBeanFactory(DefaultListableBeanFactory beanFactory)
```
    Customize the internal bean factory used by this context. Called for each AbstractApplicationContext.refresh() attempt.
    The default implementation applies this context's "allowBeanDefinitionOverriding" and "allowCircularReferences" settings, if specified. Can be overridden in subclasses to customize any of DefaultListableBeanFactory's settings.
    Parameters:
    beanFactory - the newly created bean factory for this context
    See Also:
    DefaultListableBeanFactory.setAllowBeanDefinitionOverriding(boolean), AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean), AbstractAutowireCapableBeanFactory.setAllowRawInjectionDespiteWrapping(boolean), DefaultListableBeanFactory.setAllowEagerClassLoading(boolean)
  - loadBeanDefinitions
```
protected abstract void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
                                     throws BeansException,
                                            IOException
```
    Load bean definitions into the given bean factory, typically through delegating to one or more bean definition readers.
    Parameters:
    beanFactory - the bean factory to load bean definitions into
    Throws:
    BeansException - if parsing of the bean definitions failed
    IOException - if loading of bean definition files failed
