public interface ConfigurableApplicationContext extends ApplicationContext, Lifecycle, Closeable
ApplicationContext
interface.
Configuration and lifecycle methods are encapsulated here to avoid making them obvious to ApplicationContext client code. The present methods should only be used by startup and shutdown code.

Modifier and Type | Method and Description |
---|---|
void |
addApplicationListener(ApplicationListener<?> listener)
Add a new ApplicationListener that will be notified on context events
such as context refresh and context shutdown.
|
void |
addBeanFactoryPostProcessor(BeanFactoryPostProcessor postProcessor)
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.
|
void |
addProtocolResolver(ProtocolResolver resolver)
Register the given protocol resolver with this application context,
allowing for additional resource protocols to be handled.
|
void |
close()
Close this application context, releasing all resources and locks that the
implementation might hold.
|
ConfigurableListableBeanFactory |
getBeanFactory()
Return the internal bean factory of this application context.
|
ConfigurableEnvironment |
getEnvironment()
Return the
Environment for this application context in configurable
form, allowing for further customization. |
boolean |
isActive()
Determine whether this application context is active, that is,
whether it has been refreshed at least once and has not been closed yet.
|
void |
refresh()
Load or refresh the persistent representation of the configuration, which
might be from Java-based configuration, an XML file, a properties file, a
relational database schema, or some other format.
|
void |
registerShutdownHook()
Register a shutdown hook with the JVM runtime, closing this context
on JVM shutdown unless it has already been closed at that time.
|
void |
setEnvironment(ConfigurableEnvironment environment)
Set the
Environment for this application context. |
void |
setId(String id)
Set the unique id of this application context.
|
void |
setParent(ApplicationContext parent)
Set the parent of this application context.

void setParent(ApplicationContext parent)
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.

- the factory processor to registervoid addApplicationListener(ApplicationListener<?> listener)
Note that any ApplicationListener registered here will be applied on refresh if the context is not active yet, or on the fly with the current event multicaster in case of a context that is already active.

void addProtocolResolver(ProtocolResolver resolver)
Any such resolver will be invoked ahead of this context's standard resolution rules. It may therefore also override any default rules.
void refresh() throws BeansException, IllegalStateException
As this is a startup method, it should destroy already created singletons if it fails, to avoid dangling resources. In other words, after invocation of this method, either all or no singletons at all should be instantiated.
BeansException
- if the bean factory could not be initializedIllegalStateException
- if already initialized and multiple refresh
attempts are not supportedvoid registerShutdownHook()
This method can be called multiple times. Only one shutdown hook (at max) will be registered for each context instance.

close()
void close()
Note: Does not invoke close
on a parent context;
parent contexts have their own, independent lifecycle.
This method can be called multiple times without side effects: Subsequent
close
calls on an already closed context will be ignored.

getBeanFactory()
ConfigurableListableBeanFactory getBeanFactory() throws IllegalStateException
Note: Do not use this to post-process the bean factory; singletons will already have been instantiated before. Use a BeanFactoryPostProcessor to intercept the BeanFactory setup process before beans get touched.
Generally, this internal factory will only be accessible while the context
is active, that is, in-between refresh()
and close()
.
The isActive()
flag can be used to check whether the context
is in an appropriate state.

has already been called)isActive()
