Interface ConfigurableApplicationContext

All Superinterfaces:
  ApplicationContext, ApplicationEventPublisher, BeanFactory, HierarchicalBeanFactory, Lifecycle, ListableBeanFactory, MessageSource, ResourceLoader, ResourcePatternResolver

All Known Subinterfaces:
  ConfigurablePortletApplicationContext, ConfigurableWebApplicationContext

All Known Implementing Classes:
  AbstractApplicationContext, AbstractRefreshableApplicationContext, AbstractRefreshableConfigApplicationContext, AbstractRefreshablePortletApplicationContext, AbstractRefreshableWebApplicationContext, AbstractXmlApplicationContext, ClassPathXmlApplicationContext, FileSystemXmlApplicationContext, GenericApplicationContext, GenericWebApplicationContext, ResourceAdapterApplicationContext, StaticApplicationContext, StaticPortletApplicationContext, StaticWebApplicationContext, XmlPortletApplicationContext, XmlWebApplicationContext

    public interface ConfigurableApplicationContext

extends ApplicationContext, Lifecycle

SPI interface to be implemented by most if not all application contexts. Provides facilities to configure an application context in addition to the application context client methods in the `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.

`static String` `CONFIG_LOCATION_DELIMITERS` Any number of these characters are considered delimiters between multiple context config paths in a single String value.

Method Summary
`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 beanFactoryPostProcessor)` 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` `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.
`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 an XML file, properties file, or relational database schema.
`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` `setParent(ApplicationContext parent)` Set the parent of this application context.

Field Detail

### CONFIG_LOCATION_DELIMITERS

    static final String CONFIG_LOCATION_DELIMITERS

  Any number of these characters are considered delimiters between multiple context config paths in a single String value.

  See Also:
    `AbstractRefreshableConfigApplicationContext.setConfigLocation(java.lang.String)`, `ContextLoader.CONFIG_LOCATION_PARAM`, `FrameworkServlet.setContextConfigLocation(java.lang.String)`, Constant Field Values

### LOAD_TIME_WEAVER_BEAN_NAME

    static final String LOAD_TIME_WEAVER_BEAN_NAME

  Name of the LoadTimeWeaver bean in the factory. If such a bean is supplied, the context will use a temporary ClassLoader for type matching, in order to allow the LoadTimeWeaver to process all actual bean classes.

  See Also:
    `LoadTimeWeaver`, Constant Field Values

Method Detail

### setParent

    void setParent(ApplicationContext parent)

  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.

  Parameters:
    `parent` - the parent context
  See Also:
    `ConfigurableWebApplicationContext`

### addBeanFactoryPostProcessor

    void addBeanFactoryPostProcessor(BeanFactoryPostProcessor beanFactoryPostProcessor)

  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.

  Parameters:
    `beanFactoryPostProcessor` - the factory processor to register

### addApplicationListener

    void addApplicationListener(ApplicationListener listener)

  Add a new ApplicationListener that will be notified on context events such as context refresh and context shutdown.

  Note that any ApplicationListener registered here will be applied on refresh of this context. If a listener is added after the initial refresh, it will be applied on next refresh of the context.

  Parameters:
    `listener` - the ApplicationListener to register
  See Also:
    `ContextRefreshedEvent`, `ContextClosedEvent`

### refresh

    void refresh()
                 throws BeansException,
                        IllegalStateException

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

  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 that method, either all or no singletons at all should be instantiated.

  Throws:
    `BeansException` - if the bean factory could not be initialized
    `IllegalStateException` - if already initialized and multiple refresh attempts are not supported

### registerShutdownHook

    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.

  This method can be called multiple times. Only one shutdown hook (at max) will be registered for each context instance.

  See Also:
    `Runtime.addShutdownHook(java.lang.Thread)`, `close()`

### close

    void close()

  Close this application context, releasing all resources and locks that the implementation might hold. This includes destroying all cached singleton beans.

  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.

### isActive

    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.

  Returns:
    whether the context is still active
  See Also:
    `refresh()`, `close()`, `getBeanFactory()`

### getBeanFactory

    ConfigurableListableBeanFactory getBeanFactory()
                                                   throws IllegalStateException

  Return the internal bean factory of this application context. Can be used to access specific functionality of the underlying factory.

  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, inbetween `refresh()` and `close()`. The `isActive()` flag can be used to check whether the context is in an appropriate state.

  Returns:
    the underlying bean factory
  Throws:
    `IllegalStateException` - if the context does not hold an internal bean factory (usually if `refresh()` hasn't been called yet or if `close()` has already been called)
  See Also:
    `isActive()`, `refresh()`, `close()`, `addBeanFactoryPostProcessor(org.springframework.beans.factory.config.BeanFactoryPostProcessor)`
