Class ResourcesBeanDefinitionParser

java.lang.Object

org.springframework.web.servlet.config.ResourcesBeanDefinitionParser

All Implemented Interfaces:

BeanDefinitionParser

class ResourcesBeanDefinitionParser
extends java.lang.Object
implements BeanDefinitionParser

BeanDefinitionParser that parses a resources element to register a ResourceHttpRequestHandler and register a SimpleUrlHandlerMapping for mapping resource requests, and a HttpRequestHandlerAdapter. Will also create a resource handling chain with ResourceResolvers and ResourceTransformers.

Method Detail

parse

public BeanDefinition parse(org.w3c.dom.Element element,
                            ParserContext parserContext)

Description copied from interface: BeanDefinitionParser

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.

Specified by:

parse in interface BeanDefinitionParser

Parameters:

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

Returns:

the primary BeanDefinition
