AbstractRefreshableWebApplicationContext (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版
org.springframework.web.context.support
Class AbstractRefreshableWebApplicationContext
java.lang.Object
org.springframework.core.io.DefaultResourceLoader
org.springframework.context.support.AbstractApplicationContext
org.springframework.context.support.AbstractRefreshableApplicationContext
org.springframework.web.context.support.AbstractRefreshableWebApplicationContext
- All Implemented Interfaces:
- BeanFactory, DisposableBean, HierarchicalBeanFactory, ListableBeanFactory, ApplicationContext, ApplicationEventPublisher, ConfigurableApplicationContext, Lifecycle, MessageSource, ResourceLoader, ResourcePatternResolver, ThemeSource, ConfigurableWebApplicationContext, WebApplicationContext
- Direct Known Subclasses:
- XmlWebApplicationContext
public abstract class AbstractRefreshableWebApplicationContext
- extends AbstractRefreshableApplicationContext
- 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
).

AbstractRefreshableWebApplicationContext
public AbstractRefreshableWebApplicationContext()
setServletContext
public void setServletContext(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
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(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
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(String namespace)
- Description copied from interface:
ConfigurableWebApplicationContext
- Set the namespace for this web application context,
to be used for building a default context config location.
The root web application context does not have a namespace.
- Specified by:
setNamespace
in interface ConfigurableWebApplicationContext
getNamespace
public String getNamespace()
- Description copied from interface:
ConfigurableWebApplicationContext
- Return the namespace for this web application context, if any.
- Specified by:
getNamespace
in interface ConfigurableWebApplicationContext
setConfigLocations
public void setConfigLocations(String[] locations)
- Description copied from interface:
ConfigurableWebApplicationContext
- Set the config locations for this web application context.
If not set, the implementation is supposed to use a default for the
given namespace or the root web application context, as appropriate.
- Specified by:
setConfigLocations
in interface ConfigurableWebApplicationContext
getConfigLocations
public String[] getConfigLocations()
- Description copied from interface:
ConfigurableWebApplicationContext
- Return the config locations for this web application context,
or
null
if none specified.
- Specified by:
getConfigLocations
in interface ConfigurableWebApplicationContext
getDefaultConfigLocations
protected String[] getDefaultConfigLocations()
- Return the default config locations to use, for the case where no
explicit config locations have been specified.
The default implementation returns null
,
requiring explicit config locations.
- See Also:
setConfigLocations(java.lang.String[])
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
resolvePath
protected String resolvePath(String path)
- Resolve the given path, replacing placeholders with corresponding
system property values if necessary. Applied to config locations.
- Parameters:
path
- the original file path
- Returns:
- the resolved file path
- See Also:
SystemPropertyUtils.resolvePlaceholders(java.lang.String)
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
- 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
- name of the theme
- Returns:
- the respective Theme, or
