- Method Detail
  - addFormatters
```
public void addFormatters(FormatterRegistry registry)
```
    Add Converters and Formatters in addition to the ones registered by default.
    This implementation is empty.
    
    Specified by:
    
    addFormatters in interface WebMvcConfigurer
  - configureMessageConverters
```
public void configureMessageConverters(List<HttpMessageConverter<?>> converters)
```
    Configure the HttpMessageConverters to use in argument resolvers and return value handlers that support reading and/or writing to the body of the request and response. If no message converters are added to the list, default converters are added instead.
    This implementation is empty.
    
    Specified by:
    
    configureMessageConverters in interface WebMvcConfigurer
    
    Parameters:
    converters - initially an empty list of converters
  - configureContentNegotiation
```
public void configureContentNegotiation(ContentNegotiationConfigurer configurer)
```
    Configure content negotiation options.
    This implementation is empty.
    
    Specified by:
    
    configureContentNegotiation in interface WebMvcConfigurer
  - configureAsyncSupport
```
public void configureAsyncSupport(AsyncSupportConfigurer configurer)
```
    Configure asynchronous request handling options.
    This implementation is empty.
    
    Specified by:
    
    configureAsyncSupport in interface WebMvcConfigurer
  - configurePathMatch
```
public void configurePathMatch(PathMatchConfigurer configurer)
```
    Helps with configuring HandlerMappings path matching options such as trailing slash match, suffix registration, path matcher and path helper. Configured path matcher and path helper instances are shared for:
    - RequestMappings
    - ViewControllerMappings
    - ResourcesMappings
    This implementation is empty.
    Specified by:
    
    configurePathMatch in interface WebMvcConfigurer
  - addArgumentResolvers
```
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers)
```
    Add resolvers to support custom controller method argument types.
    This does not override the built-in support for resolving handler method arguments. To customize the built-in support for argument resolution, configure RequestMappingHandlerAdapter directly.
    This implementation is empty.
    
    Specified by:
    
    addArgumentResolvers in interface WebMvcConfigurer
    
    Parameters:
    argumentResolvers - initially an empty list
  - addReturnValueHandlers
```
public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers)
```
    Add handlers to support custom controller method return value types.
    Using this option does not override the built-in support for handling return values. To customize the built-in support for handling return values, configure RequestMappingHandlerAdapter directly.
    This implementation is empty.
    
    Specified by:
    
    addReturnValueHandlers in interface WebMvcConfigurer
    
    Parameters:
    returnValueHandlers - initially an empty list
  - configureHandlerExceptionResolvers
```
public void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers)
```
    Configure the HandlerExceptionResolvers to handle unresolved controller exceptions. If no resolvers are added to the list, default exception resolvers are added instead.
    This implementation is empty.
    
    Specified by:
    
    configureHandlerExceptionResolvers in interface WebMvcConfigurer
    
    Parameters:
    exceptionResolvers - initially an empty list
  - addInterceptors
```
public void addInterceptors(InterceptorRegistry registry)
```
    Add Spring MVC lifecycle interceptors for pre- and post-processing of controller method invocations. Interceptors can be registered to apply to all requests or be limited to a subset of URL patterns.
    This implementation is empty.
    
    Specified by:
    
    addInterceptors in interface WebMvcConfigurer
  - addViewControllers
```
public void addViewControllers(ViewControllerRegistry registry)
```
    Add view controllers to create a direct mapping between a URL path and view name without the need for a controller in between.
    This implementation is empty.
    
    Specified by:
    
    addViewControllers in interface WebMvcConfigurer
  - addResourceHandlers
```
public void addResourceHandlers(ResourceHandlerRegistry registry)
```
    Add handlers to serve static resources such as images, js, and, css files from specific locations under web application root, the classpath, and others.
    This implementation is empty.
    
    Specified by:
    
    addResourceHandlers in interface WebMvcConfigurer
  - configureDefaultServletHandling
```
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer)
```
    Configure a handler to delegate unhandled requests by forwarding to the Servlet container's "default" servlet. A common use case for this is when the DispatcherServlet is mapped to "/" thus overriding the Servlet container's default handling of static resources.
    This implementation is empty.
    
    Specified by:
    
    configureDefaultServletHandling in interface WebMvcConfigurer
  - getValidator
```
public Validator getValidator()
```
    Provide a custom Validator instead of the one created by default. The default implementation, assuming JSR-303 is on the classpath, is: LocalValidatorFactoryBean. Leave the return value as null to keep the default.
    This implementation returns null.
    
    Specified by:
    
    getValidator in interface WebMvcConfigurer
  - getMessageCodesResolver
```
public MessageCodesResolver getMessageCodesResolver()
```
    Provide a custom MessageCodesResolver for building message codes from data binding and validation error codes. Leave the return value as null to keep the default.
    This implementation returns null.
    
    Specified by:
    
    getMessageCodesResolver in interface WebMvcConfigurer
