public class GenericWebApplicationContext
extends GenericApplicationContext
implements WebApplicationContext, ThemeSource

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 - the path to the resource

Returns:

the corresponding Resource handle

See Also:

ServletContextResource

getResourcePatternResolver

protected ResourcePatternResolver getResourcePatternResolver()

This implementation supports pattern matching in unexpanded WARs too.

Overrides:

getResourcePatternResolver in class AbstractApplicationContext

Returns:

the ResourcePatternResolver for this context

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 - the name of the theme

Returns:

the corresponding Theme, or null if none defined. Note that, by convention, a ThemeSource should at least be able to return a default Theme for the default theme name "theme" but may also return default Themes for other theme names.

AbstractThemeResolver.ORIGINAL_DEFAULT_THEME_NAME
