  • Method Details

    • setMessageReaders

      public void setMessageReaders(List<org.springframework.http.codec.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<org.springframework.http.codec.HttpMessageReader<?>> getMessageReaders()
      Return the configurer for HTTP message readers.

    • setWebBindingInitializer

      public void setWebBindingInitializer(@Nullable org.springframework.web.bind.support.WebBindingInitializer webBindingInitializer)
      Provide a WebBindingInitializer with "global" initialization to apply to every DataBinder instance.

    • getWebBindingInitializer

      @Nullable public org.springframework.web.bind.support.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.

    • setBlockingExecutor

      public void setBlockingExecutor(@Nullable Executor executor)
      Configure an executor to invoke blocking controller methods with.

      By default, this is not set in which case controller methods are invoked without the use of an Executor.

      Parameters:
      executor - the task executor to use
      Since:
      6.1

    • setBlockingMethodPredicate

      public void setBlockingMethodPredicate(Predicate<org.springframework.web.method.HandlerMethod> predicate)
      Provide a predicate to decide which controller methods to invoke through the configured blockingExecutor.

      If an executor is configured, the default predicate matches controller methods whose return type is not recognized by the configured ReactiveAdapterRegistry.

      Parameters:
      predicate - the predicate to use
      Since:
      6.1

    • setReactiveAdapterRegistry

      public void setReactiveAdapterRegistry(@Nullable org.springframework.core.ReactiveAdapterRegistry registry)
      Configure the registry for adapting various reactive types.

      By default this is an instance of ReactiveAdapterRegistry with default settings.

    • getReactiveAdapterRegistry

      @Nullable public org.springframework.core.ReactiveAdapterRegistry getReactiveAdapterRegistry()
      Return the configured registry for adapting reactive types.

    • setApplicationContext

      public void setApplicationContext(org.springframework.context.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 org.springframework.context.ApplicationContextAware

    • afterPropertiesSet

      public void afterPropertiesSet() throws Exception
      Specified by:
      afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean
      Throws:
      Exception

    • 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(org.springframework.web.server.ServerWebExchange exchange, Object handler)
      Description copied from interface: HandlerAdapter
      Handle the request with the given handler, previously checked via HandlerAdapter.supports(Object).

      Implementations should consider the following for exception handling:

      • Handle invocation exceptions within this method.
      • Set an exception handler on the returned HandlerResult to handle deferred exceptions from asynchronous return values, and to handle exceptions from response rendering.
      • Implement DispatchExceptionHandler to extend exception handling to exceptions that occur before a handler is selected.
      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 HandlerResult, or completes empty if the request is fully handled; any error signal would not be handled within the DispatcherHandler, and would instead be processed by the chain of registered WebExceptionHandlers at the end of the WebFilter chain

    • handleError

      public reactor.core.publisher.Mono<HandlerResult> handleError(org.springframework.web.server.ServerWebExchange exchange, Throwable ex)
      Description copied from interface: DispatchExceptionHandler
      Handle the given exception, mapping it to a HandlerResult that can then be used to render an HTTP response.
      Specified by:
      handleError in interface DispatchExceptionHandler
      Parameters:
      exchange - the current exchange
      ex - the exception to handle
      Returns:
      a Mono that emits a HandlerResult or an error signal with the original exception if it remains not handled
