public abstract class AbstractApplicationContext
extends org.springframework.core.io.DefaultResourceLoader
implements ConfigurableApplicationContext

Abstract implementation of the ApplicationContext interface. Doesn't mandate the type of storage used for configuration; simply implements common context functionality. Uses the Template Method design pattern, requiring concrete subclasses to implement abstract methods.

In contrast to a plain BeanFactory, an ApplicationContext is supposed to detect special beans defined in its internal bean factory: Therefore, this class automatically registers BeanFactoryPostProcessors, BeanPostProcessors, and ApplicationListeners which are defined as beans in the context.

A MessageSource may also be supplied as a bean in the context, with the name "messageSource"; otherwise, message resolution is delegated to the parent context. Furthermore, a multicaster for application events can be supplied as an "applicationEventMulticaster" bean of type ApplicationEventMulticaster in the context; otherwise, a default multicaster of type SimpleApplicationEventMulticaster will be used.

Implements resource loading by extending DefaultResourceLoader. Consequently treats non-URL resource paths as class path resources (supporting full class path resource names that include the package path, e.g. "mypackage/myresource.dat"), unless the DefaultResourceLoader.getResourceByPath(java.lang.String) method is overridden in a subclass.

Called by both close() and a JVM shutdown hook, if any.

另请参阅:

ContextClosedEvent, destroyBeans(), close(), registerShutdownHook()

destroyBeans

protected void destroyBeans()

Template method for destroying all beans that this context manages. The default implementation destroy all cached singletons in this context, invoking DisposableBean.destroy() and/or the specified "destroy-method".

Template method which can be overridden to add context-specific shutdown work. The default implementation is empty.

                         String defaultMessage,
                         Locale locale)

从接口复制的说明: MessageSource

Try to resolve the message. Return default message if no message was found.

指定者:

getMessage 在接口中 MessageSource

参数:

code - the code to lookup up, such as 'calculator.noRateSet'. Users of this class are encouraged to base message names on the relevant fully qualified class name, thus avoiding conflict and ensuring maximum clarity.

args - an array of arguments that will be filled in for params within the message (params look like "{0}", "{1,date}", "{2,time}" within a message), or null if none.

defaultMessage - a default message to return if the lookup fails

locale - the locale in which to do the lookup

返回:

the resolved message if the lookup was successful; otherwise the default message passed as a parameter

code - the code to lookup up, such as 'calculator.noRateSet'

args - an array of arguments that will be filled in for params within the message (params look like "{0}", "{1,date}", "{2,time}" within a message), or null if none.

public String getMessage(MessageSourceResolvable resolvable,
                         Locale locale)
                  throws NoSuchMessageException

从接口复制的说明: MessageSource

Try to resolve the message using all the attributes contained within the MessageSourceResolvable argument that was passed in.

NOTE: We must throw a NoSuchMessageException on this method since at the time of calling this method we aren't able to determine if the defaultMessage property of the resolvable is null or not.

指定者:

getMessage 在接口中 MessageSource

参数:

resolvable - the value object storing attributes required to resolve a message

locale - the locale in which to do the lookup

返回:

the resolved message

抛出:

NoSuchMessageException - if the message wasn't found

getInternalParentMessageSource

抛出:

start

public void start()

从接口复制的说明: Lifecycle

Start this component.

Should not throw an exception if the component is already running.

In the case of a container, this will propagate the start signal to all components that apply.

指定者:

start 在接口中 Lifecycle

另请参阅:

SmartLifecycle.isAutoStartup()

stop

public void stop()

从接口复制的说明: Lifecycle

Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.

Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, a given bean's destroy method will be called without any consideration of stop signals upfront.

Should not throw an exception if the component is not running (not started yet).

In the case of a container, this will propagate the stop signal to all components that apply.

指定者:

stop 在接口中 Lifecycle

另请参阅:

SmartLifecycle.stop(Runnable), DisposableBean.destroy()

isRunning

public boolean isRunning()

从接口复制的说明: Lifecycle

Check whether this component is currently running.

In the case of a container, this will return true only if all components that apply are currently running.

指定者:

isRunning 在接口中 Lifecycle

返回:

whether the component is currently running

refreshBeanFactory

protected abstract void refreshBeanFactory()
                                    throws org.springframework.beans.BeansException,
                                           IllegalStateException

Subclasses must implement this method to perform the actual configuration load. The method is invoked by refresh() before any other initialization work.

A subclass will either create a new bean factory and hold a reference to it, or return a single BeanFactory instance that it holds. In the latter case, it will usually throw an IllegalStateException if refreshing the context more than once.

抛出:

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

IllegalStateException - if already initialized and multiple refresh attempts are not supported

closeBeanFactory

protected abstract void closeBeanFactory()

Subclasses must implement this method to release their internal bean factory. This method gets invoked by close() after all other shutdown work.

Should never throw an exception but rather log shutdown failures.

getBeanFactory

public abstract org.springframework.beans.factory.config.ConfigurableListableBeanFactory getBeanFactory()
                                                                                                 throws IllegalStateException

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

返回:

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

抛出:

IllegalStateException - if the context does not hold an internal bean factory yet (usually if refresh() has never been called) or if the context has been closed already

另请参阅:

refreshBeanFactory(), closeBeanFactory()

toString

public String toString()

Return information about this context.

覆盖:
