类 ContextSingletonBeanFactoryLocator

  • 所有已实现的接口:
    BeanFactoryLocator
    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.

    • 构造器详细资料

      • ContextSingletonBeanFactoryLocator

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

      • getInstance

        public static BeanFactoryLocator getInstance()
                                      throws BeansException
        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.
        返回:
        the corresponding BeanFactoryLocator instance
        抛出:
        BeansException - in case of factory loading failure

      • getInstance

        public static BeanFactoryLocator getInstance​(String selector)
                                      throws BeansException
        Returns an instance which uses 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.
        参数:
        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.
        返回:
        the corresponding BeanFactoryLocator instance
        抛出:
        BeansException - in case of factory loading failure

      • createDefinition

        protected BeanFactory createDefinition​(String resourceLocation,
                                       String factoryKey)
        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 ClassPathXmlApplicationContext.

        覆盖:
        createDefinition 在类中 SingletonBeanFactoryLocator
        参数:
        resourceLocation - the resource location for this factory group
        factoryKey - the bean name of the factory to obtain
        返回:
        the corresponding BeanFactory reference
