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 org.springframework.web.servlet.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.

    • loadBeanDefinitions

      protected void loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory beanFactory) throws org.springframework.beans.BeansException, IOException
      Loads the bean definitions via an XmlBeanDefinitionReader.
      Specified by:
      loadBeanDefinitions in class org.springframework.context.support.AbstractRefreshableApplicationContext
      Throws:

      IOException

    • initBeanDefinitionReader

      protected void initBeanDefinitionReader(org.springframework.beans.factory.xml.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<? extends org.springframework.beans.factory.xml.BeanDefinitionDocumentReader>)

    • loadBeanDefinitions

      protected void loadBeanDefinitions(org.springframework.beans.factory.xml.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

    • 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").
