Direct Known Subclasses:

AbstractRefreshableApplicationContext, GenericApplicationContext

public abstract class AbstractApplicationContext

extends DefaultResourceLoader

implements ConfigurableApplicationContext

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

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

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

Implements resource loading through extending DefaultResourceLoader. Therefore, treats plain resource paths as class path resources (only supporting full class path resource names that include the package path, e.g. "mypackage/myresource.dat").

public AbstractApplicationContext(ApplicationContext parent)

Create a new AbstractApplicationContext with the given parent context.

Parameters:

parent - the parent context

Method Detail

getParent

public ApplicationContext getParent()

Return the parent context, or null if there is no parent (that is, this context is the root of the context hierarchy).

Specified by:

getParent in interface ApplicationContext

Returns:

the parent context, or null if there is no parent

setDisplayName

protected void setDisplayName(String displayName)

Set a friendly name for this context. Typically done during initialization of concrete context implementations.

getDisplayName

public String getDisplayName()

Return a friendly name for this context.

Specified by:

getDisplayName in interface ApplicationContext

Returns:

a display name for this context

getStartupDate

public long getStartupDate()

Return the timestamp (ms) when this context was first loaded.

Specified by:

getStartupDate in interface ApplicationContext

Returns:

the timestamp (ms) when this context was first loaded

publishEvent

public void publishEvent(ApplicationEvent event)

Publish the given event to all listeners.

Note: Listeners get initialized after the MessageSource, to be able to access it within listener implementations. Thus, MessageSource implementation cannot publish events.

Specified by:

publishEvent in interface ApplicationContext

Parameters:

event - event to publish (may be application-specific or a standard framework event)

See Also:

RequestHandledEvent

setParent

public void setParent(ApplicationContext parent)

Description copied from interface: ConfigurableApplicationContext

Set the parent of this application context.

Note that the parent shouldn't be changed: It should only be set outside a constructor if it isn't available when an object of this class is created, for example in case of WebApplicationContext setup.

Specified by:

setParent in interface ConfigurableApplicationContext

Parameters:

parent - the parent context

See Also:

ConfigurableWebApplicationContext

addBeanFactoryPostProcessor

public void addBeanFactoryPostProcessor(BeanFactoryPostProcessor beanFactoryPostProcessor)

Description copied from interface: ConfigurableApplicationContext

Add a new BeanFactoryPostProcessor that will get applied to the internal bean factory of this application context on refresh, before any of the bean definitions get evaluated. To be invoked during context configuration.

Specified by:

addBeanFactoryPostProcessor in interface ConfigurableApplicationContext

Parameters:

beanFactoryPostProcessor - the factory processor to register

getBeanFactoryPostProcessors

public List getBeanFactoryPostProcessors()

Return the list of BeanPostProcessors that will get applied to beans created with this factory.

refresh

public void refresh()
             throws BeansException,
                    IllegalStateException

Description copied from interface: ConfigurableApplicationContext

Load or refresh the persistent representation of the configuration, which might an XML file, properties file, or relational database schema.

Specified by:

refresh in interface ConfigurableApplicationContext

Throws:

BeansException - if the bean factory could not be initialized

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

getResourcePatternResolver

protected ResourcePatternResolver getResourcePatternResolver()

Return the ResourcePatternResolver to use for resolving location patterns into Resource instances. Default is PathMatchingResourcePatternResolver, supporting Ant-style location patterns.

Can be overridden in subclasses, for extended resolution strategies, for example in a web environment.

Do not call this when needing to resolve a location pattern. Call the context's getResources method instead, which will delegate to the ResourcePatternResolver.

See Also:

getResources(java.lang.String), PathMatchingResourcePatternResolver

postProcessBeanFactory

protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
                               throws BeansException

Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for registering special BeanPostProcessors etc in certain ApplicationContext implementations.

Parameters:

beanFactory - the bean factory used by the application context

Throws:

BeansException - in case of errors

onRefresh

protected void onRefresh()
                  throws BeansException

refresh()

addListener

protected void addListener(ApplicationListener listener)

Subclasses can invoke this method to register a listener. Any beans in the context that are listeners are automatically added.

Parameters:

listener - the listener to register

close

public void close()

Destroy the singletons in the bean factory of this application context.

Specified by:

close in interface ConfigurableApplicationContext

getBean

public Object getBean(String name)
               throws BeansException

Description copied from interface: BeanFactory

Return an instance, which may be shared or independent, of the given bean name. This method allows a Spring bean factory 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.

This method delegates to 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 return

Returns:

the instance of the bean

Throws:

BeansException - if the bean could not be obtained

getBean

public Object getBean(String name,
                      Class requiredType)
               throws BeansException

Description copied from interface: BeanFactory

Return an instance (possibly shared or independent) of the given bean name.

Behaves the same as getBean(String), but provides a measure of type safety by throwing a Spring BeansException 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 getBean(String).

Specified by:

getBean in interface BeanFactory

Parameters:

name - the name of the bean to return

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 (never null)

Throws:

BeansException - if the bean could not be created

containsBean

public boolean containsBean(String name)

Description copied from interface: BeanFactory

Does this bean factory contain a bean definition with the given name?

Will ask the parent factory if the bean cannot be found in this factory instance.

Specified by:

containsBean in interface BeanFactory

Parameters:

name - the name of the bean to query

Returns:

whether a bean with the given name is defined

isSingleton

public boolean isSingleton(String name)
                    throws NoSuchBeanDefinitionException

Description copied from interface: BeanFactory

Is this bean a singleton? That is, will getBean() always return the same object?

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:

is this bean a singleton

Specified by:

getType in interface BeanFactory

Parameters:

name - the name of the bean to query

Returns:

the type of the bean, or null if not determinable

Throws:

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 bean factory instance that it holds. In the latter case, it will usually throw an IllegalStateException if refreshing the context more than once.

Throws:

BeansException - if initialization of the bean factory failed

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

See Also:

refresh()

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.

Specified by:

getBeanFactory in interface ConfigurableApplicationContext

Returns:

this application context's internal bean factory

Throws:

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

See Also:

refresh()

toString

public String toString()

Return information about this context.
