Method Details

replyPayloadToFlux

public WebFluxMessageHandlerSpec replyPayloadToFlux(boolean replyPayloadToFlux)

The boolean flag to identify if the reply payload should be as a Flux from the response body or as resolved value from the Mono of the response body. Defaults to false - simple value is pushed downstream. Makes sense when expectedResponseType is configured.

Parameters:

replyPayloadToFlux - represent reply payload as a Flux or as a value from the Mono.

Returns:

the spec

Since:

5.0.1

• WebFluxRequestExecutingMessageHandler.setReplyPayloadToFlux(boolean)

bodyExtractor

public WebFluxMessageHandlerSpec bodyExtractor(BodyExtractor<?,? super ClientHttpResponse> bodyExtractor)

Specify a BodyExtractor as an alternative to the expectedResponseType to allow to get low-level access to the received ClientHttpResponse.

Parameters:

bodyExtractor - the BodyExtractor to use.

Returns:

the spec

Since:

5.0.1

See Also:

• WebFluxRequestExecutingMessageHandler.setBodyExtractor(BodyExtractor)

publisherElementType

public WebFluxMessageHandlerSpec publisherElementType(Class<?> publisherElementType)

Configure a type for a request Publisher elements.

Parameters:

publisherElementType - the type of the request Publisher elements.

Returns:

the spec

Since:

5.2

See Also:

• WebFluxRequestExecutingMessageHandler.setPublisherElementType(java.lang.Class<?>)

publisherElementType

public WebFluxMessageHandlerSpec publisherElementType(ParameterizedTypeReference<?> publisherElementType)

Configure a ParameterizedTypeReference for a request Publisher elements.

Parameters:

publisherElementType - the type of the request Publisher elements.

Returns:

the spec

Since:

5.2

See Also:

• WebFluxRequestExecutingMessageHandler.setPublisherElementType(java.lang.Class<?>)

publisherElementTypeFunction

public <P> WebFluxMessageHandlerSpec publisherElementTypeFunction(Function<Message<P>,?> typeFunction)

Configure a Function to evaluate a request Publisher elements type at runtime against a request message.

Type Parameters:

P - the expected payload type.

Parameters:

typeFunction - the Function to evaluate a type for the request Publisher elements.

Returns:

the spec

Since:

5.2

See Also:

• WebFluxRequestExecutingMessageHandler.setPublisherElementTypeExpression(Expression)

publisherElementTypeExpression

public WebFluxMessageHandlerSpec publisherElementTypeExpression(Expression publisherElementTypeExpression)
