public abstract class AbstractXmlApplicationContext
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 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.

protected void loadBeanDefinitions(XmlBeanDefinitionReader reader) throws BeansException, IOException
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.
