public class XmlWebApplicationContext extends AbstractRefreshableWebApplicationContext
WebApplicationContext
implementation which takes its configuration from XML documents, understood by anXmlBeanDefinitionReader
. This is essentially the equivalent ofGenericXmlApplicationContext
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 ofFrameworkServlet
. Config locations can either denote concrete files like "/WEB-INF/context.xml" or Ant-style patterns like "/WEB-INF/*-context.xml" (seePathMatcher
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.- Author:

Method Detail
loadBeanDefinitions
protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory) throws BeansException, IOException
Loads the bean definitions via an XmlBeanDefinitionReader.- Specified by:
loadBeanDefinitions
in classAbstractRefreshableApplicationContext
- Parameters:
beanFactory
- the bean factory to load bean definitions into- Throws:
BeansException
- if parsing of the bean definitions failedIOException
- 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 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:
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 classAbstractRefreshableConfigApplicationContext
- Returns:
- an array of default config locations, if any
- See Also:
AbstractRefreshableConfigApplicationContext.setConfigLocations(java.lang.String...)
