public class XmlWebApplicationContext extends AbstractRefreshableWebApplicationContext
WebApplicationContext
implementation
which takes its configuration from XML documents, understood by an
XmlBeanDefinitionReader
.
This is essentially the equivalent of
GenericXmlApplicationContext
for a web environment.
By default, the configuration will be taken from "/WEB-INF/applicationContext.xml" for the root context, and "/WEB-INF/test-servlet.xml" for a context with the namespace "test-servlet" (like for a DispatcherServlet instance with the servlet-name "test").
The config location defaults can be overridden via the "contextConfigLocation"
context-param of ContextLoader
and servlet
init-param of FrameworkServlet
. 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 WebApplicationContext that reads in a different bean definition format,
create an analogous subclass of AbstractRefreshableWebApplicationContext
.
Such a context implementation can be specified as "contextClass" context-param
for ContextLoader or "contextClass" init-param for FrameworkServlet.

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.
