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, ornull
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)
AConfigurableApplicationContext
is expected for resolving expressions in method argument default values as well as for detecting@ControllerAdvice
beans.- Specified by:
setApplicationContext
in interfaceApplicationContextAware
- 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 containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,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 interfaceInitializingBean
- 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 thisHandlerAdapter
supports the givenhandler
.- Specified by:
supports
in interfaceHandlerAdapter
- 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 toset an exception handler
on theHandlerResult
so that may also be applied later after result handling.- Specified by:
handle
in interfaceHandlerAdapter
- Parameters:
exchange
- current server exchangehandler
- the selected handler which must have been previously checked viaHandlerAdapter.supports(Object)
- Returns:
Mono
that emits a singleHandlerResult
or none if the request has been fully handled and doesn't require further handling.
