public abstract class AbstractRefreshablePortletApplicationContext
extends AbstractRefreshableConfigApplicationContext
implements WebApplicationContext, ConfigurablePortletApplicationContext

AbstractRefreshableApplicationContext subclass which implements the ConfigurablePortletApplicationContext interface for portlet environments. Provides a "configLocations" property, to be populated through the ConfigurablePortletApplicationContext interface on portlet 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.

This is the portlet context to be subclassed for a different bean definition format. Such a context implementation can be specified as "contextClass" init-param for FrameworkPortlet, replacing the default XmlPortletApplicationContext. It will then automatically receive the "contextConfigLocation" init-param.

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

Constructor Detail

AbstractRefreshablePortletApplicationContext

public AbstractRefreshablePortletApplicationContext()
Method Detail

setParent

public void setParent(ApplicationContext parent)
Set the parent of this application context.

Note that the parent shouldn't be changed: It should only be set outside a constructor if it isn't available when an object of this class is created, for example in case of WebApplicationContext setup.

The parent environment is merged with this (child) application context environment if the parent is non-null and its environment is an instance of ConfigurableEnvironment.

The parent environment is delegated to this (child) context if the parent is a ConfigurableApplicationContext implementation.

The parent servlet context is delegated to this (child) context if the parent is a WebApplicationContext implementation.

Specified by:
setParent in interface ConfigurableApplicationContext
Overrides:
setParent in class AbstractApplicationContext
Parameters:
parent - the parent context
See Also:
ConfigurableEnvironment.merge(ConfigurableEnvironment)

getServletContext

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

Also available for a Portlet application, in addition to the PortletContext.

Specified by:
getServletContext in interface WebApplicationContext

setPortletContext

public void setPortletContext(PortletContext portletContext)
Description copied from interface: ConfigurablePortletApplicationContext
Set the PortletContext for this portlet application context.

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

Specified by:
setPortletContext in interface ConfigurablePortletApplicationContext
See Also:
ConfigurableApplicationContext.refresh()

getPortletContext

public PortletContext getPortletContext()
Description copied from interface: ConfigurablePortletApplicationContext
Return the standard Portlet API PortletContext for this application.

Specified by:
getPortletContext in interface ConfigurablePortletApplicationContext

setPortletConfig

public void setPortletConfig(PortletConfig portletConfig)
Description copied from interface: ConfigurablePortletApplicationContext
Set the PortletConfig for this portlet application context.

Specified by:
setPortletConfig in interface ConfigurablePortletApplicationContext
See Also:
ConfigurableApplicationContext.refresh()

getPortletConfig

public PortletConfig getPortletConfig()
Description copied from interface: ConfigurablePortletApplicationContext
Return the PortletConfig for this portlet application context, if any.

Specified by:
getPortletConfig in interface ConfigurablePortletApplicationContext

setNamespace

public void setNamespace(String namespace)
Description copied from interface: ConfigurablePortletApplicationContext
Set the namespace for this portlet application context, to be used for building a default context config location.

Specified by:
setNamespace in interface ConfigurablePortletApplicationContext

getNamespace

public String getNamespace()
Description copied from interface: ConfigurablePortletApplicationContext
Return the namespace for this web application context, if any.

Specified by:
getNamespace in interface ConfigurablePortletApplicationContext

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 ConfigurablePortletApplicationContext
Overrides:
getConfigLocations in class AbstractRefreshableConfigApplicationContext
Returns:
an array of resource locations, or null if none
See Also:
AbstractApplicationContext.getResources(java.lang.String), AbstractApplicationContext.getResourcePatternResolver()

postProcessBeanFactory

protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
Register request/session scopes, a PortletContextAwareProcessor, etc.

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

createEnvironment

protected ConfigurableEnvironment createEnvironment()
Create and return a new StandardPortletEnvironment.

Overrides:
createEnvironment in class AbstractApplicationContext

getResourceByPath

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

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

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:
PortletContextResourcePatternResolver

customizeBeanFactory

protected void customizeBeanFactory(DefaultListableBeanFactory beanFactory)
Description copied from class: AbstractRefreshableApplicationContext
Customize the internal bean factory used by this context. Called for each AbstractApplicationContext.refresh() attempt.

The default implementation applies this context's "allowBeanDefinitionOverriding" and "allowCircularReferences" settings, if specified. Can be overridden in subclasses to customize any of DefaultListableBeanFactory's settings.

Overrides:
customizeBeanFactory in class AbstractRefreshableApplicationContext
Parameters:
beanFactory - the newly created bean factory for this context
