- All Implemented Interfaces:
    Closeable, AutoCloseable, Aware, BeanFactory, BeanNameAware, DisposableBean, HierarchicalBeanFactory, InitializingBean, ListableBeanFactory, ApplicationContext, ApplicationEventPublisher, ConfigurableApplicationContext, Lifecycle, MessageSource, EnvironmentCapable, ResourceLoader, ResourcePatternResolver
  Direct Known Subclasses:
    ClassPathXmlApplicationContext, FileSystemXmlApplicationContext

      public abstract class AbstractXmlApplicationContext
      extends AbstractRefreshableConfigApplicationContext

  Convenient base class for `ApplicationContext` implementations, drawing configuration from XML documents containing bean definitions understood by an `XmlBeanDefinitionReader`.

  Subclasses just have to implement the `getConfigResources()` and/or the `AbstractRefreshableConfigApplicationContext.getConfigLocations()` method. Furthermore, they might override the `DefaultResourceLoader.getResourceByPath(java.lang.String)` hook to interpret relative paths in an environment-specific fashion, and/or `AbstractApplicationContext.getResourcePatternResolver()` for extended pattern resolution.

- - ### Constructor Detail

    - #### AbstractXmlApplicationContext

          public AbstractXmlApplicationContext()

      Create a new AbstractXmlApplicationContext with no parent.

    - #### AbstractXmlApplicationContext

          public AbstractXmlApplicationContext(ApplicationContext parent)

      Create a new AbstractXmlApplicationContext with the given parent context.
      Parameters:
        `parent` - the parent context

  - ### Method Detail

    - #### setValidating

          public void setValidating(boolean validating)

      Set whether to use XML validation. Default is `true`.

    - #### loadBeanDefinitions

          protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
                                      throws BeansException,
                                             IOException

      Loads the bean definitions via an XmlBeanDefinitionReader.
      Specified by:
        `loadBeanDefinitions` in class `AbstractRefreshableApplicationContext`
      Parameters:
        `beanFactory` - the bean factory to load bean definitions into
      Throws:
        `BeansException` - if parsing of the bean definitions failed
        `IOException` - if loading of bean definition files failed
      See Also:
        `XmlBeanDefinitionReader`, `initBeanDefinitionReader(org.springframework.beans.factory.xml.XmlBeanDefinitionReader)`, `loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory)`

    - #### initBeanDefinitionReader

          protected void initBeanDefinitionReader(XmlBeanDefinitionReader reader)

      Initialize the bean definition reader used for loading the bean definitions of this context. Default implementation is empty.

      Can be overridden in subclasses, e.g. for turning off XML validation or using a different XmlBeanDefinitionParser implementation.

      Parameters:
        `reader` - the bean definition reader used by this context
      See Also:
        `XmlBeanDefinitionReader.setDocumentReaderClass(java.lang.Class<?>)`

    - #### loadBeanDefinitions

          protected void loadBeanDefinitions(XmlBeanDefinitionReader reader)
                                      throws BeansException,
                                             IOException

      Load the bean definitions with the given XmlBeanDefinitionReader.

      The lifecycle of the bean factory is handled by the `AbstractRefreshableApplicationContext.refreshBeanFactory()` method; hence this method is just supposed to load and/or register bean definitions.

      Parameters:
        `reader` - the XmlBeanDefinitionReader to use
      Throws:
        `BeansException` - in case of bean registration errors
        `IOException` - if the required XML document isn't found
      See Also:
        `AbstractRefreshableApplicationContext.refreshBeanFactory()`, `AbstractRefreshableConfigApplicationContext.getConfigLocations()`, `AbstractApplicationContext.getResources(java.lang.String)`, `AbstractApplicationContext.getResourcePatternResolver()`

    - #### getConfigResources

          protected Resource[] getConfigResources()

      Return an array of Resource objects, referring to the XML bean definition files that this context should be built with.

      The default implementation returns `null`. Subclasses can override this to provide pre-built Resource objects rather than location Strings.

      Returns:
        an array of Resource objects, or `null` if none

        `AbstractRefreshableConfigApplicationContext.getConfigLocations()`
