public class ContextSingletonBeanFactoryLocator extends SingletonBeanFactoryLocator
Variant of SingletonBeanFactoryLocator
which creates its internal bean factory reference as an
ApplicationContext
instead of
SingletonBeanFactoryLocator's simple BeanFactory. For almost all usage scenarios,
this will not make a difference, since within that ApplicationContext or BeanFactory
you are still free to define either BeanFactory or ApplicationContext instances.
The main reason one would need to use this class is if bean post-processing
(or other ApplicationContext specific features are needed in the bean reference
definition itself).
Note: This class uses classpath*:beanRefContext.xml as the default resource location for the bean factory reference definition files. It is not possible nor legal to share definitions with SingletonBeanFactoryLocator at the same time.

protected BeanFactory |
createDefinition(String resourceLocation,
String factoryKey)
Overrides the default method to create definition object as an ApplicationContext
instead of the default BeanFactory.

destroyDefinition(BeanFactory groupDef,
String selector)
Overrides the default method to operate on an ApplicationContext, invoking
ConfigurableApplicationContext.close() . |
static BeanFactoryLocator |
getInstance()
Returns an instance which uses the default "classpath*:beanRefContext.xml", as
the name of the definition file(s).
|
static BeanFactoryLocator |
getInstance(String selector)
Returns an instance which uses the specified selector, as the name of the
definition file(s).

protected void |
initializeDefinition(BeanFactory groupDef)
Overrides the default method to refresh the ApplicationContext, invoking
ConfigurableApplicationContext.refresh() . |

getResources
method will be called with this value to get
all resources having that name. These resources will then be combined to form a
definition. In the case where the name uses a Spring "classpath:" prefix, or
a standard URL prefix, then only one resource file will be loaded as the
definition.selector
- the location of the resource(s) which will be read and
combined to form the definition for the BeanFactoryLocator instance.
Any such files must form a valid ApplicationContext definition.BeansException
