直接已知子类:

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. org.springframework.web.context.support.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.

构造器详细资料

AbstractRefreshableApplicationContext

public AbstractRefreshableApplicationContext()

Create a new AbstractRefreshableApplicationContext with no parent.

AbstractRefreshableApplicationContext

public AbstractRefreshableApplicationContext(@Nullable
                                             ApplicationContext parent)

Create a new AbstractRefreshableApplicationContext with the given parent context.

参数:

parent - the parent context

方法详细资料

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".

另请参阅:

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.

另请参阅:

AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean)

refreshBeanFactory

protected final void refreshBeanFactory()
                                 throws org.springframework.beans.BeansException

方法实现说明:是AbstractApplicationContext对象的子类,用于springmvc来刷新容器调用

指定者:

refreshBeanFactory 在类中 AbstractApplicationContext

抛出:

org.springframework.beans.BeansException - if initialization of the bean factory failed

cancelRefresh

protected void cancelRefresh(org.springframework.beans.BeansException ex)

从类复制的说明: AbstractApplicationContext

Cancel this context's refresh attempt, resetting the active flag after an exception got thrown.

覆盖:

cancelRefresh 在类中 AbstractApplicationContext

参数:

ex - the exception that led to the cancellation

closeBeanFactory

protected final void closeBeanFactory()

从类复制的说明: 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.

指定者:

closeBeanFactory 在类中 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 org.springframework.beans.factory.config.ConfigurableListableBeanFactory getBeanFactory()

从类复制的说明: 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.

指定者:

getBeanFactory 在接口中 ConfigurableApplicationContext

指定者:

getBeanFactory 在类中 AbstractApplicationContext

返回:

this application context's internal bean factory (never null)

另请参阅:

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.

覆盖:

assertBeanFactoryActive 在类中 AbstractApplicationContext

createBeanFactory

protected org.springframework.beans.factory.support.DefaultListableBeanFactory createBeanFactory()

方法实现说明:为我们的spring 上下文创建我们的内置的beanFactory

customizeBeanFactory

protected void customizeBeanFactory(org.springframework.beans.factory.support.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.

参数:

beanFactory - the newly created bean factory for this context

另请参阅:

DefaultListableBeanFactory.setAllowBeanDefinitionOverriding(boolean), AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean), AbstractAutowireCapableBeanFactory.setAllowRawInjectionDespiteWrapping(boolean), DefaultListableBeanFactory.setAllowEagerClassLoading(boolean)

loadBeanDefinitions

protected abstract void loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory beanFactory)
                                     throws org.springframework.beans.BeansException,
                                            IOException

Load bean definitions into the given bean factory, typically through delegating to one or more bean definition readers.

参数:

beanFactory - the bean factory to load bean definitions into

抛出:

org.springframework.beans.BeansException - if parsing of the bean definitions failed

IOException - if loading of bean definition files failed
