java.lang.Object
   org.springframework.beans.factory.access.SingletonBeanFactoryLocator
      org.springframework.context.access.ContextSingletonBeanFactoryLocator

ContextSingletonBeanFactoryLocator
public class ContextSingletonBeanFactoryLocator extends SingletonBeanFactoryLocator (Code)

Variant of org.springframework.beans.factory.access.SingletonBeanFactoryLocator which creates its internal bean factory reference as an org.springframework.context.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.

Constructor Summary
protected  ContextSingletonBeanFactoryLocator(String resourceLocation)
     Constructor which uses the the specified name as the resource name of the definition file(s).

Method Summary
protected  BeanFactorycreateDefinition(String resourceLocation, String factoryKey)
     Overrides the default method to create definition object as an ApplicationContext instead of the default BeanFactory.
protected  voiddestroyDefinition(BeanFactory groupDef, String selector)
     Overrides the default method to operate on an ApplicationContext, invoking ConfigurableApplicationContext.refresh ConfigurableApplicationContext.close() .
public static  BeanFactoryLocatorgetInstance()
     Returns an instance which uses the default "classpath*:beanRefContext.xml", as the name of the definition file(s).
public static  BeanFactoryLocatorgetInstance(String selector)
     Returns an instance which uses the the specified selector, as the name of the definition file(s).
protected  voidinitializeDefinition(BeanFactory groupDef)
     Overrides the default method to refresh the ApplicationContext, invoking ConfigurableApplicationContext.refresh ConfigurableApplicationContext.refresh() .


Constructor Detail
ContextSingletonBeanFactoryLocator
protected ContextSingletonBeanFactoryLocator(String resourceLocation)(Code)
Constructor which uses the the specified name as the resource name of the definition file(s).
Parameters:
  resourceLocation - the Spring resource location to use(either a URL or a "classpath:" / "classpath*:" pseudo URL)




Method Detail
createDefinition
protected BeanFactory createDefinition(String resourceLocation, String factoryKey)(Code)
Overrides the default method to create definition object as an ApplicationContext instead of the default BeanFactory. This does not affect what can actually be loaded by that definition.

The default implementation simply builds a org.springframework.context.support.ClassPathXmlApplicationContext .




destroyDefinition
protected void destroyDefinition(BeanFactory groupDef, String selector)(Code)
Overrides the default method to operate on an ApplicationContext, invoking ConfigurableApplicationContext.refresh ConfigurableApplicationContext.close() .



getInstance
public static BeanFactoryLocator getInstance() throws BeansException(Code)
Returns an instance which uses the default "classpath*:beanRefContext.xml", as the name of the definition file(s). All resources returned by the current thread's context class loader's getResources method with this name will be combined to create a definition, which is just a BeanFactory. the corresponding BeanFactoryLocator instance
throws:
  BeansException - in case of factory loading failure



getInstance
public static BeanFactoryLocator getInstance(String selector) throws BeansException(Code)
Returns an instance which uses the the specified selector, as the name of the definition file(s). In the case of a name with a Spring "classpath*:" prefix, or with no prefix, which is treated the same, the current thread's context class loader's 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.
Parameters:
  selector - the location of the resource(s) which will be read andcombined to form the definition for the BeanFactoryLocator instance.Any such files must form a valid ApplicationContext definition. the corresponding BeanFactoryLocator instance
throws:
  BeansException - in case of factory loading failure



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