```
public WebMvcConfigurerAdapter()
```
- 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 for reading or writing to the body of the request or response. If no converters are added, a default list of converters is registered.
    Note that adding converters to the list, turns off default converter registration. To simply add a converter without impacting default registration, consider using the method WebMvcConfigurer.extendMessageConverters(java.util.List) instead.
    This implementation is empty.
    
    Specified by:
    
    configureMessageConverters in interface WebMvcConfigurer
    
    Parameters:
    
    converters - initially an empty list of converters
  - extendMessageConverters
```
public void extendMessageConverters(List<HttpMessageConverter<?>> converters)
```
    A hook for extending or modifying 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.
    This implementation is empty.
    
    Specified by:
    
    extendMessageConverters in interface WebMvcConfigurer
    
    Parameters:
    
    converters - the list of configured converters to extend.
  - 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: OptionalValidatorFactoryBean. Leave the return value as null to keep the default.
    This implementation returns null
    
    Specified by:
    
    getValidator in interface WebMvcConfigurer
  - 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
  - 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 is empty.
    
    Specified by:
    
    getMessageCodesResolver in interface WebMvcConfigurer
  - 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.
    Note that interceptors registered here only apply to controllers and not to resource handler requests. To intercept requests for static resources either declare a MappedInterceptor bean or switch to advanced configuration mode by extending WebMvcConfigurationSupport and then override resourceHandlerMapping.
    This implementation is empty.
    
    Specified by:
    
    addInterceptors in interface WebMvcConfigurer
  - addViewControllers
```
public void addViewControllers(ViewControllerRegistry registry)
```
    Configure simple automated controllers pre-configured with the response status code and/or a view to render the response body. This is useful in cases where there is no need for custom controller logic -- e.g. render a home page, perform simple site URL redirects, return a 404 status with HTML content, a 204 with no content, and more.
    This implementation is empty.
    
    Specified by:
    
    addViewControllers in interface WebMvcConfigurer
  - configureViewResolvers
```
public void configureViewResolvers(ViewResolverRegistry registry)
```
    Configure view resolvers to translate String-based view names returned from controllers into concrete View implementations to perform rendering with.
    This implementation is empty.
    
    Specified by:
    
    configureViewResolvers 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
