    • 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.

      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.

      @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:

    • 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 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.
