Class AnnotationDrivenBeanDefinitionParser

java.lang.Object
  org.springframework.web.servlet.config.AnnotationDrivenBeanDefinitionParser

All Implemented Interfaces:

BeanDefinitionParser

public class AnnotationDrivenBeanDefinitionParser
extends Object
implements BeanDefinitionParser

BeanDefinitionParser that parses the annotation-driven element to configure a Spring MVC web application.

Responsible for:

1. Registering a DefaultAnnotationHandlerMapping bean for mapping HTTP Servlet Requests to @Controller methods using @RequestMapping annotations.
2. Registering a AnnotationMethodHandlerAdapter bean for invoking annotated @Controller methods. Will configure the HandlerAdapter's webBindingInitializer property for centrally configuring @Controller DataBinder instances:
   • Configures the conversionService if specified, otherwise defaults to a fresh ConversionService instance created by the default FormattingConversionServiceFactoryBean.
   • Configures the validator if specified, otherwise defaults to a fresh Validator instance created by the default LocalValidatorFactoryBean if the JSR-303 API is present on the classpath.
   • Configures standard HttpMessageConverters, including the Jaxb2RootElementHttpMessageConverter if JAXB2 is present on the classpath, and the MappingJacksonHttpMessageConverter if Jackson is present on the classpath.

public BeanDefinition parse(Element element,
                            ParserContext parserContext)

Description copied from interface: BeanDefinitionParser

Parse the specified Element and register the resulting BeanDefinition(s) with the ParserContext.getRegistry() 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
