接口 ConfigurableApplicationContext

字段详细资料

• 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.

• CONVERSION_SERVICE_BEAN_NAME

  static final String CONVERSION_SERVICE_BEAN_NAME

  Name of the ConversionService bean in the factory. If none is supplied, default conversion rules apply.

  从以下版本开始:

  3.0

  ConversionService, 常量字段值

• 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.

  从以下版本开始:

  2.5

• ENVIRONMENT_BEAN_NAME

  static final String ENVIRONMENT_BEAN_NAME

  Name of the Environment bean in the factory.

  3.1

• SYSTEM_PROPERTIES_BEAN_NAME

  static final String SYSTEM_PROPERTIES_BEAN_NAME

  Name of the System properties bean in the factory.

方法详细资料

• setId

  void setId​(String id)

  Set the unique id of this application context.

  从以下版本开始:

  3.0

• 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.

  参数:

  parent - the parent context

  另请参阅:

  ConfigurableWebApplicationContext

• setEnvironment

  void setEnvironment​(ConfigurableEnvironment environment)

  Set the Environment for this application context.

  参数:

  environment - the new environment

  从以下版本开始:

  3.1

• getEnvironment

  ConfigurableEnvironment getEnvironment()

  Return the Environment for this application context in configurable form, allowing for further customization.

  指定者:

  getEnvironment 在接口中 EnvironmentCapable

  从以下版本开始:

  3.1

• addBeanFactoryPostProcessor

  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. To be invoked during context configuration.

  参数:

  postProcessor - 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 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.

  参数:

  listener - the ApplicationListener to register

  ContextRefreshedEvent, ContextClosedEvent

• addProtocolResolver

  void addProtocolResolver​(ProtocolResolver resolver)

  Register the given protocol resolver with this application context, allowing for additional resource protocols to be handled.

  Any such resolver will be invoked ahead of this context's standard resolution rules. It may therefore also override any default rules.

  从以下版本开始:

  4.3

• refresh

  void refresh()
        throws BeansException,
               IllegalStateException

  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.

  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.

  抛出:

  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.

  另请参阅:

  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.

  指定者:

  close 在接口中 AutoCloseable

  指定者:

  close 在接口中 Closeable

• 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.

  返回:

  whether the context is still active

  另请参阅:

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

  返回:

  the underlying bean factory

  抛出:

  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)

  isActive(), refresh(), close(), addBeanFactoryPostProcessor(org.springframework.beans.factory.config.BeanFactoryPostProcessor)
