public interface BeanDefinitionParser
```
Interface used by the DefaultBeanDefinitionDocumentReader to handle custom, top-level (directly under <beans/>) tags.
Implementations are free to turn the metadata in the custom tag into as many BeanDefinitions as required.
The parser locates a BeanDefinitionParser from the associated NamespaceHandler for the namespace in which the custom tag resides.

```
@Nullable
BeanDefinition parse(Element element,
                     ParserContext parserContext)
```
    Parse the specified Element and register the resulting BeanDefinition(s) with the BeanDefinitionRegistry embedded in the supplied ParserContext.
    Implementations must return the primary BeanDefinition that results from the parse if they will ever be used in a nested fashion (for example as an inner tag in a <property/> tag). Implementations may return null if they will not be used in a nested fashion.
    参数:
    element - the element that is to be parsed into one or more BeanDefinitions
    parserContext - the object encapsulating the current state of the parsing process; provides access to a BeanDefinitionRegistry
    返回:
    the primary BeanDefinition
