类 AbstractRefreshableApplicationContext

构造器详细资料

• AbstractRefreshableApplicationContext

  public AbstractRefreshableApplicationContext()

  Create a new AbstractRefreshableApplicationContext with no parent.

• AbstractRefreshableApplicationContext

  public AbstractRefreshableApplicationContext​(ApplicationContext parent)

  Create a new AbstractRefreshableApplicationContext with the given parent context.

  参数:

  parent - the parent context

方法详细资料

• setAllowBeanDefinitionOverriding

  public void setAllowBeanDefinitionOverriding​(boolean allowBeanDefinitionOverriding)

  Set whether it should be allowed to override bean definitions by registering a different definition with the same name, automatically replacing the former. If not, an exception will be thrown. Default is "true".

  另请参阅:

  DefaultListableBeanFactory.setAllowBeanDefinitionOverriding(boolean)

• setAllowCircularReferences

  public void setAllowCircularReferences​(boolean allowCircularReferences)

  Set whether to allow circular references between beans - and automatically try to resolve them.

  Default is "true". Turn this off to throw an exception when encountering a circular reference, disallowing them completely.

  AbstractAutowireCapableBeanFactory.setAllowCircularReferences(boolean)

• refreshBeanFactory

  protected final void refreshBeanFactory()
                                   throws BeansException

  This implementation performs an actual refresh of this context's underlying bean factory, shutting down the previous bean factory (if any) and initializing a fresh bean factory for the next phase of the context's lifecycle.

  指定者:

  refreshBeanFactory 在类中 AbstractApplicationContext

  抛出:

  BeansException - if initialization of the bean factory failed

• cancelRefresh

  protected void cancelRefresh​(BeansException ex)

  从类复制的说明: AbstractApplicationContext
  Cancel this context's refresh attempt, resetting the active flag after an exception got thrown.

  覆盖:

  cancelRefresh 在类中 AbstractApplicationContext

  参数:

  ex - the exception that led to the cancellation

• closeBeanFactory

  protected final void closeBeanFactory()

  从类复制的说明: AbstractApplicationContext
  Subclasses must implement this method to release their internal bean factory. This method gets invoked by AbstractApplicationContext.close() after all other shutdown work.

  Should never throw an exception but rather log shutdown failures.

  指定者:

  closeBeanFactory 在类中 AbstractApplicationContext

• hasBeanFactory

  protected final boolean hasBeanFactory()

  Determine whether this context currently holds a bean factory, i.e. has been refreshed at least once and not been closed yet.

• getBeanFactory

  public final ConfigurableListableBeanFactory getBeanFactory()

  从类复制的说明: AbstractApplicationContext
  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

  指定者:

  getBeanFactory 在类中 AbstractApplicationContext

  返回:

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

  另请参阅:

  AbstractApplicationContext.refreshBeanFactory(), AbstractApplicationContext.closeBeanFactory()

• assertBeanFactoryActive

  protected void assertBeanFactoryActive()

  Overridden to turn it into a no-op: With AbstractRefreshableApplicationContext, getBeanFactory() serves a strong assertion for an active context anyway.

  覆盖:

  assertBeanFactoryActive 在类中 AbstractApplicationContext

• createBeanFactory

  protected DefaultListableBeanFactory createBeanFactory()

  Create an internal bean factory for this context. Called for each AbstractApplicationContext.refresh() attempt.

  The default implementation creates a DefaultListableBeanFactory with the internal bean factory of this context's parent as parent bean factory. Can be overridden in subclasses, for example to customize DefaultListableBeanFactory's settings.

  返回:

  the bean factory for this context

• customizeBeanFactory

  protected void customizeBeanFactory​(DefaultListableBeanFactory beanFactory)

  Customize the internal bean factory used by this context. Called for each AbstractApplicationContext.refresh() attempt.

  The default implementation applies this context's "allowBeanDefinitionOverriding" and "allowCircularReferences" settings, if specified. Can be overridden in subclasses to customize any of DefaultListableBeanFactory's settings.

  参数:

  beanFactory - the newly created bean factory for this context

• loadBeanDefinitions

  protected abstract void loadBeanDefinitions​(DefaultListableBeanFactory beanFactory)
                                       throws BeansException,
                                              IOException

  Load bean definitions into the given bean factory, typically through delegating to one or more bean definition readers.

  参数:

  beanFactory - the bean factory to load bean definitions into

  抛出:

  BeansException - if parsing of the bean definitions failed

  IOException - if loading of bean definition files failed
