public abstract class AbstractRefreshableWebApplicationContext
extends AbstractRefreshableConfigApplicationContext
implements ConfigurableWebApplicationContext, ThemeSource

AbstractRefreshableApplicationContext subclass which implements the ConfigurableWebApplicationContext interface for web environments. Provides a "configLocations" property, to be populated through the ConfigurableWebApplicationContext interface on web application startup.

This class is as easy to subclass as AbstractRefreshableApplicationContext: All you need to implements is the AbstractRefreshableApplicationContext.loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory) method; see the superclass javadoc for details. Note that implementations are supposed to load bean definitions from the files specified by the locations returned by the getConfigLocations() 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 DefaultResourceLoader.

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

This is the web context to be subclassed for a different bean definition format. Such a context implementation can be specified as "contextClass" context-param for ContextLoader or as "contextClass" init-param for FrameworkServlet, replacing the default XmlWebApplicationContext. It will then automatically receive the "contextConfigLocation" context-param or init-param, respectively.

Note that WebApplicationContext implementations are generally supposed to configure themselves based on the configuration received through the ConfigurableWebApplicationContext interface. In contrast, a standalone application context might allow for configuration in custom startup code (for example, GenericApplicationContext).

Method Detail

setServletContext

public void setServletContext(@Nullable
                              ServletContext servletContext)

Description copied from interface: ConfigurableWebApplicationContext

Set the ServletContext for this web application context.

Does not cause an initialization of the context: refresh needs to be called after the setting of all configuration properties.

Specified by:

setServletContext in interface ConfigurableWebApplicationContext

See Also:

ConfigurableApplicationContext.refresh()

getServletContext

@Nullable
public ServletContext getServletContext()

Description copied from interface: WebApplicationContext

Return the standard Servlet API ServletContext for this application.

Specified by:

getServletContext in interface WebApplicationContext

setServletConfig

public void setServletConfig(@Nullable
                             ServletConfig servletConfig)

Description copied from interface: ConfigurableWebApplicationContext

Set the ServletConfig for this web application context. Only called for a WebApplicationContext that belongs to a specific Servlet.

Specified by:

setServletConfig in interface ConfigurableWebApplicationContext

See Also:

ConfigurableApplicationContext.refresh()

getServletConfig

@Nullable
public ServletConfig getServletConfig()

Description copied from interface: ConfigurableWebApplicationContext

Return the ServletConfig for this web application context, if any.

Specified by:

getServletConfig in interface ConfigurableWebApplicationContext

setNamespace

public void setNamespace(@Nullable
                         String namespace)

Description copied from interface: ConfigurableWebApplicationContext

getNamespace

@Nullable
public String getNamespace()

Description copied from interface: ConfigurableWebApplicationContext

Return the namespace for this web application context, if any.

Specified by:

getConfigLocations

public String[] getConfigLocations()

Description copied from class: AbstractRefreshableConfigApplicationContext

Return an array of resource locations, referring to the XML bean definition files that this context should be built with. Can also include location patterns, which will get resolved via a ResourcePatternResolver.

The default implementation returns null. Subclasses can override this to provide a set of resource locations to load bean definitions from.

Specified by:

getConfigLocations in interface ConfigurableWebApplicationContext

Overrides:

getConfigLocations in class AbstractRefreshableConfigApplicationContext

Returns:

an array of resource locations, or null if none

Specified by:

getApplicationName in interface ApplicationContext

Overrides:

getApplicationName in class AbstractApplicationContext

Returns:

a name for the deployed application, or the empty String by default

createEnvironment

protected ConfigurableEnvironment createEnvironment()

Create and return a new StandardServletEnvironment. Subclasses may override in order to configure the environment or specialize the environment type returned.

Overrides:

createEnvironment in class AbstractApplicationContext

postProcessBeanFactory

protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)

Register request/session scopes, a ServletContextAwareProcessor, etc.

Overrides:

postProcessBeanFactory in class AbstractApplicationContext

Parameters:

beanFactory - the bean factory used by the application context

getResourceByPath

path - the path to the resource

Returns:

the corresponding Resource handle

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()

initPropertySources

protected void initPropertySources()

Replace any stub property sources with actual instances.

Replace Servlet-related property sources.

Overrides:

initPropertySources in class AbstractApplicationContext

getTheme

@Nullable
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.
