public class XmlWebApplicationContext
- extends AbstractRefreshableWebApplicationContext
WebApplicationContext implementation that takes configuration from an XML document,
understood by an XmlBeanDefinitionReader. This is essentially the equivalent of
AbstractXmlApplicationContext and its subclasses 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 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.

XmlWebApplicationContext
public XmlWebApplicationContext()
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.setValidating(boolean),
XmlBeanDefinitionReader.setParserClass(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(),
AbstractRefreshableWebApplicationContext.getConfigLocations(),
AbstractApplicationContext.getResources(java.lang.String),
AbstractRefreshableWebApplicationContext.getResourcePatternResolver()
getDefaultConfigLocations
protected String[] getDefaultConfigLocations()
- The default location for the root context is "/WEB-INF/applicationContext.xml",
and "/WEB-INF/test-servlet.xml" for a context with the namespace "test-servlet"
(like for a DispatcherServlet instance with the servlet-name "test").
- Overrides:
getDefaultConfigLocations in class AbstractRefreshableWebApplicationContext
- See Also:
AbstractRefreshableWebApplicationContext.setConfigLocations(java.lang.String[])
