    public class XmlPortletApplicationContext

extends AbstractRefreshablePortletApplicationContext

Portlet-based `WebApplicationContext` implementation which takes its configuration from XML documents, understood by an `XmlBeanDefinitionReader`. This is essentially the equivalent of `AbstractXmlApplicationContext` for a portlet environment.

By default, the configuration will be taken from "/WEB-INF/applicationContext.xml" for the root context, and "/WEB-INF/test-portlet.xml" for a context with the namespace "test-portlet" (like for a DispatcherPortlet instance with the portlet-name "test").

The config location defaults can be overridden via the "contextConfigLocation" portlet init-param of `FrameworkPortlet`. Config locations can either denote concrete files like "/WEB-INF/context.xml" or Ant-style patterns like "/WEB-INF/*-context.xml" (see `PathMatcher` javadoc for pattern details).

Note: In case of multiple config locations, later bean definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra XML file.

For a Portlet-based context that reads in a different bean definition format, create an analogous subclass of `AbstractRefreshablePortletApplicationContext`. Such a context implementation can be specified as "contextClass" init-param for a FrameworkPortlet instance.

Method Detail

### 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 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.setValidationMode(int)`, `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 refreshBeanFactory method; therefore this method is just supposed to load and/or register bean definitions.

  Delegates to a ResourcePatternResolver for resolving location patterns into Resource instances.

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

### getDefaultConfigLocations

    protected String[] getDefaultConfigLocations()

  The default location for the root context is "/WEB-INF/applicationContext.xml", and "/WEB-INF/test-portlet.xml" for a context with the namespace "test-portlet" (like for a DispatcherPortlet instance with the portlet-name "test").

  Overrides:
    `getDefaultConfigLocations` in class `AbstractRefreshableConfigApplicationContext`
  Returns:
    an array of default config locations, if any
  See Also:
    `AbstractRefreshableConfigApplicationContext.setConfigLocations(java.lang.String[])`
