## org.springframework.context.support
Class AbstractXmlApplicationContext

    java.lang.Object
      org.springframework.core.io.DefaultResourceLoader
          org.springframework.context.support.AbstractApplicationContext
              org.springframework.context.support.AbstractRefreshableApplicationContext
                  org.springframework.context.support.AbstractRefreshableConfigApplicationContext
                      org.springframework.context.support.AbstractXmlApplicationContext

All Implemented Interfaces:
  BeanFactory, BeanNameAware, DisposableBean, HierarchicalBeanFactory, InitializingBean, ListableBeanFactory, ApplicationContext, ApplicationEventPublisher, ConfigurableApplicationContext, Lifecycle, MessageSource, 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

### loadBeanDefinitions

    protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
                                throws 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:
    `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 beanDefinitionReader)

  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:
    `beanDefinitionReader` - 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
  See Also:
    `AbstractRefreshableConfigApplicationContext.getConfigLocations()`
