Description copied from class: WebMvcConfigurationSupport

Override this method to configure content negotiation.

Overrides:

configureContentNegotiation in class WebMvcConfigurationSupport

See Also:

• DefaultServletHandlerConfigurer

configureAsyncSupport

protected void configureAsyncSupport(AsyncSupportConfigurer configurer)

Description copied from class: WebMvcConfigurationSupport

See Also:

• AsyncSupportConfigurer

configureDefaultServletHandling

protected void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer)

Description copied from class: WebMvcConfigurationSupport

Override this method to configure "default" Servlet handling.

Overrides:

See Also:

• DefaultServletHandlerConfigurer

addFormatters

protected void addFormatters(FormatterRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to add custom Converter and/or Formatter delegates to the common FormattingConversionService.

Overrides:

addFormatters in class WebMvcConfigurationSupport

See Also:

• WebMvcConfigurationSupport.mvcConversionService()

addInterceptors

protected void addInterceptors(InterceptorRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to add Spring MVC interceptors for pre- and post-processing of controller invocation.

Overrides:

addInterceptors in class WebMvcConfigurationSupport

See Also:

• InterceptorRegistry

addResourceHandlers

protected void addResourceHandlers(ResourceHandlerRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to add resource handlers for serving static resources.

Overrides:

addResourceHandlers in class WebMvcConfigurationSupport

See Also:

• ResourceHandlerRegistry

addCorsMappings

protected void addCorsMappings(CorsRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to configure cross-origin requests processing.

Overrides:

addCorsMappings in class WebMvcConfigurationSupport

See Also:

• CorsRegistry

addViewControllers

protected void addViewControllers(ViewControllerRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to add view controllers.

Overrides:

addViewControllers in class WebMvcConfigurationSupport

See Also:

• ViewControllerRegistry

configureViewResolvers

protected void configureViewResolvers(ViewResolverRegistry registry)

Description copied from class: WebMvcConfigurationSupport

Override this method to configure view resolution.

Overrides:

configureViewResolvers in class WebMvcConfigurationSupport

See Also:

• ViewResolverRegistry

addArgumentResolvers

protected void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers)

Description copied from class: WebMvcConfigurationSupport

Add custom HandlerMethodArgumentResolvers to use in addition to the ones registered by default.

Custom argument resolvers are invoked before built-in resolvers except for those that rely on the presence of annotations (for example, @RequestParameter, @PathVariable, etc). The latter can be customized by configuring the RequestMappingHandlerAdapter directly.

Overrides:

addArgumentResolvers in class WebMvcConfigurationSupport

Parameters:

argumentResolvers - the list of custom converters (initially an empty list)

addReturnValueHandlers

protected void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers)

Description copied from class: WebMvcConfigurationSupport

Add custom HandlerMethodReturnValueHandlers in addition to the ones registered by default.

Custom return value handlers are invoked before built-in ones except for those that rely on the presence of annotations (for example, @ResponseBody, @ModelAttribute, etc). The latter can be customized by configuring the RequestMappingHandlerAdapter directly.

Overrides:

addReturnValueHandlers in class WebMvcConfigurationSupport

Parameters:

returnValueHandlers - the list of custom handlers (initially an empty list)

configureMessageConverters

protected void configureMessageConverters(List<HttpMessageConverter<?>> converters)

Description copied from class: WebMvcConfigurationSupport

Override this method to add custom HttpMessageConverters to use with the RequestMappingHandlerAdapter and the ExceptionHandlerExceptionResolver.

Adding converters to the list turns off the default converters that would otherwise be registered by default. Also see WebMvcConfigurationSupport.addDefaultHttpMessageConverters(java.util.List<org.springframework.http.converter.HttpMessageConverter<?>>) for adding default message converters.

Overrides:

configureMessageConverters in class WebMvcConfigurationSupport

Parameters:

converters - a list to add message converters to (initially an empty list)

extendMessageConverters

protected void extendMessageConverters(List<HttpMessageConverter<?>> converters)

Description copied from class: WebMvcConfigurationSupport

Override this method to extend or modify the list of converters after it has been configured. This may be useful for example to allow default converters to be registered and then insert a custom converter through this method.

Overrides:

extendMessageConverters in class WebMvcConfigurationSupport

Parameters:

converters - the list of configured converters to extend

configureHandlerExceptionResolvers

protected void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers)

Description copied from class: WebMvcConfigurationSupport

Override this method to configure the list of HandlerExceptionResolvers to use.

Adding resolvers to the list turns off the default resolvers that would otherwise be registered by default. Also see WebMvcConfigurationSupport.addDefaultHandlerExceptionResolvers(java.util.List<org.springframework.web.servlet.HandlerExceptionResolver>, org.springframework.web.accept.ContentNegotiationManager) that can be used to add the default exception resolvers.

Overrides:

configureHandlerExceptionResolvers in class WebMvcConfigurationSupport

Parameters:

exceptionResolvers - a list to add exception resolvers to (initially an empty list)

extendHandlerExceptionResolvers

protected void extendHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers)

Description copied from class: WebMvcConfigurationSupport

Override this method to extend or modify the list of HandlerExceptionResolvers after it has been configured.

This may be useful for example to allow default resolvers to be registered and then insert a custom one through this method.

Overrides:

extendHandlerExceptionResolvers in class WebMvcConfigurationSupport

Parameters:

exceptionResolvers - the list of configured resolvers to extend.

configureErrorResponseInterceptors

protected void configureErrorResponseInterceptors(List<ErrorResponse.Interceptor> interceptors)

Description copied from class: WebMvcConfigurationSupport
