public class GenericWebApplicationContext
extends GenericApplicationContext
implements WebApplicationContext

Subclass of GenericApplicationContext, suitable for web environments. Implements the WebApplicationContext interface, but not ConfigurableWebApplicationContext, as it is not intended for declarative setup in web.xml. Instead, it is designed for programmatic setup, for example for building nested contexts.

If you intend to implement a WebApplicationContext that reads bean definitions from configuration files, consider deriving from AbstractRefreshableWebApplicationContext, reading the bean definitions in an implementation of the loadBeanDefinitions method.

Interprets resource paths as servlet context resources, i.e. as paths beneath the web application root. Absolute paths, e.g. for files outside the web app root, can be accessed via "file:" URLs, as implemented by AbstractApplicationContext.

In addition to the special beans detected by AbstractApplicationContext, this class detects a ThemeSource bean in the context, with the name "themeSource".

Constructor Detail

GenericWebApplicationContext

public GenericWebApplicationContext()
Create a new GenericWebApplicationContext.

See Also:
setServletContext(javax.servlet.ServletContext), GenericApplicationContext.registerBeanDefinition(java.lang.String, org.springframework.beans.factory.config.BeanDefinition), AbstractApplicationContext.refresh()

GenericWebApplicationContext

public GenericWebApplicationContext(DefaultListableBeanFactory beanFactory)
Create a new GenericWebApplicationContext with the given DefaultListableBeanFactory.

Parameters:
beanFactory - the DefaultListableBeanFactory instance to use for this context
See Also:
setServletContext(javax.servlet.ServletContext), GenericApplicationContext.registerBeanDefinition(java.lang.String, org.springframework.beans.factory.config.BeanDefinition), AbstractApplicationContext.refresh()
Method Detail

setServletContext

public void setServletContext(ServletContext servletContext)
Set the ServletContext that this WebApplicationContext runs in.

getServletContext

public ServletContext getServletContext()
Description copied from interface: WebApplicationContext
Return the standard Servlet API ServletContext for this application.

Specified by:
getServletContext in interface WebApplicationContext

postProcessBeanFactory

protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
Register ServletContextAwareProcessor.

Overrides:
postProcessBeanFactory in class AbstractApplicationContext
Parameters:
beanFactory - the bean factory used by the application context
See Also:
ServletContextAwareProcessor

getResourceByPath

protected Resource getResourceByPath(String path)
This implementation supports file paths beneath the root of the ServletContext.

Overrides:
getResourceByPath in class DefaultResourceLoader
Parameters:
path - path to the resource
Returns:
Resource handle
See Also:
ServletContextResource

getResourcePatternResolver

protected ResourcePatternResolver getResourcePatternResolver()
This implementation supports pattern matching in unexpanded WARs too.

Overrides:
getResourcePatternResolver in class AbstractApplicationContext
See Also:
ServletContextResourcePatternResolver

onRefresh

protected void onRefresh()
Initialize the theme capability.

Overrides:
onRefresh in class AbstractApplicationContext
See Also:
AbstractApplicationContext.refresh()

getTheme

public Theme getTheme(String themeName)
Description copied from interface: ThemeSource
Return the Theme instance for the given theme name. The returned Theme will resolve theme-specific messages, codes, file paths, etc (e.g. CSS and image files in a web environment).

Specified by:
getTheme in interface ThemeSource
Parameters:
themeName - name of the theme
Returns:
the respective Theme, or null if none defined
