Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`afterPropertiesSet()`	Invoked by the containing `BeanFactory` after it has set all bean properties and satisfied `BeanFactoryAware`, `ApplicationContextAware` etc.
`ArgumentResolverConfigurer`	`getArgumentResolverConfigurer()`	Return the configured resolvers for controller method arguments.
`List<HttpMessageReader<?>>`	`getMessageReaders()`	Return the configurer for HTTP message readers.
`ReactiveAdapterRegistry`	`getReactiveAdapterRegistry()`	Return the configured registry for adapting reactive types.
`WebBindingInitializer`	`getWebBindingInitializer()`	Return the configured WebBindingInitializer, or `null` if none.
`reactor.core.publisher.Mono<HandlerResult>`	`handle(ServerWebExchange exchange, Object handler)`	Handle the request with the given handler.
`void`	`setApplicationContext(ApplicationContext applicationContext)`	A `ConfigurableApplicationContext` is expected for resolving expressions in method argument default values as well as for detecting `@ControllerAdvice` beans.
`void`	`setArgumentResolverConfigurer(ArgumentResolverConfigurer configurer)`	Configure resolvers for controller method arguments.
`void`	`setMessageReaders(List<HttpMessageReader<?>> messageReaders)`	Configure HTTP message readers to de-serialize the request body with.
`void`	`setReactiveAdapterRegistry(ReactiveAdapterRegistry registry)`	Configure the registry for adapting various reactive types.
`void`	`setWebBindingInitializer(WebBindingInitializer webBindingInitializer)`	Provide a WebBindingInitializer with "global" initialization to apply to every DataBinder instance.
`boolean`	`supports(Object handler)`	Whether this `HandlerAdapter` supports the given `handler`.

public RequestMappingHandlerAdapter()
```
- Method Detail
  - setMessageReaders
```
public void setMessageReaders(List<HttpMessageReader<?>> messageReaders)
```
    Configure HTTP message readers to de-serialize the request body with.
    By default this is set to ServerCodecConfigurer's readers with defaults.
  - getMessageReaders
```
public List<HttpMessageReader<?>> getMessageReaders()
```
    Return the configurer for HTTP message readers.
  - setWebBindingInitializer
```
public void setWebBindingInitializer(@Nullable
                                     WebBindingInitializer webBindingInitializer)
```
    Provide a WebBindingInitializer with "global" initialization to apply to every DataBinder instance.
  - getWebBindingInitializer
```
@Nullable
public WebBindingInitializer getWebBindingInitializer()
```
    Return the configured WebBindingInitializer, or null if none.
  - setArgumentResolverConfigurer
```
public void setArgumentResolverConfigurer(@Nullable
                                          ArgumentResolverConfigurer configurer)
```
    Configure resolvers for controller method arguments.
  - getArgumentResolverConfigurer
```
@Nullable
public ArgumentResolverConfigurer getArgumentResolverConfigurer()
```
    Return the configured resolvers for controller method arguments.
  - setReactiveAdapterRegistry
```
public void setReactiveAdapterRegistry(@Nullable
                                       ReactiveAdapterRegistry registry)
```
    Configure the registry for adapting various reactive types.
    By default this is an instance of ReactiveAdapterRegistry with default settings.
  - getReactiveAdapterRegistry
```
@Nullable
public ReactiveAdapterRegistry getReactiveAdapterRegistry()
```
    Return the configured registry for adapting reactive types.
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    A ConfigurableApplicationContext is expected for resolving expressions in method argument default values as well as for detecting @ControllerAdvice beans.
    Specified by:
    setApplicationContext in interface ApplicationContextAware
    Parameters:
    applicationContext - the ApplicationContext object to be used by this object
    See Also:
    BeanInitializationException
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws Exception
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
    Throws:
    Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason
  - supports
```
public boolean supports(Object handler)
```
    Description copied from interface: HandlerAdapter
    Whether this HandlerAdapter supports the given handler.
    Specified by:
    supports in interface HandlerAdapter
    Parameters:
    handler - the handler object to check
    Returns:
    whether or not the handler is supported
  - handle
```
public reactor.core.publisher.Mono<HandlerResult> handle(ServerWebExchange exchange,
                                                         Object handler)
```
    Description copied from interface: HandlerAdapter
    Handle the request with the given handler.
    Implementations are encouraged to handle exceptions resulting from the invocation of a handler in order and if necessary to return an alternate result that represents an error response.
    Furthermore since an async HandlerResult may produce an error later during result handling implementations are also encouraged to set an exception handler on the HandlerResult so that may also be applied later after result handling.
    Specified by:
    handle in interface HandlerAdapter
    Parameters:
    exchange - current server exchange
    handler - the selected handler which must have been previously checked via HandlerAdapter.supports(Object)
    Returns:
    Mono that emits a single HandlerResult or none if the request has been fully handled and doesn't require further handling.
