setBodyExtractor(BodyExtractor<?,? super ClientHttpResponse> bodyExtractor)
Specify a

setEncodingMode(DefaultUriBuilderFactory.EncodingMode encodingMode)
Set the encoding mode to use.
|
void |
setPublisherElementType(Class<?> publisherElementType)
Configure a type for a request
Publisher elements. |
void |
setPublisherElementTypeExpression(Expression publisherElementTypeExpression)
Configure a SpEL expression to evaluate a request
Publisher elements type at runtime against
a request message. |
void |
setReplyPayloadToFlux(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. |
