Method Detail

onStatus

WebClient.ResponseSpec onStatus(Predicate<HttpStatus> statusPredicate,
                                Function<ClientResponse,reactor.core.publisher.Mono<? extends Throwable>> exceptionFunction)

Register a custom error function that gets invoked when the given HttpStatus predicate applies. The exception returned from the function will be returned from bodyToMono(Class) and bodyToFlux(Class).

By default, an error handler is registered that throws a WebClientResponseException when the response status code is 4xx or 5xx.

Parameters:

statusPredicate - a predicate that indicates whether exceptionFunction applies

NOTE: if the response is expected to have content, the exceptionFunction should consume it. If not, the content will be automatically drained to ensure resources are released.

exceptionFunction - the function that returns the exception

Returns:

this builder

bodyToMono

<T> reactor.core.publisher.Mono<T> bodyToMono(Class<T> bodyType)

Extract the body to a Mono. By default, if the response has status code 4xx or 5xx, the Mono will contain a WebClientException. This can be overridden with onStatus(Predicate, Function).

Type Parameters:

T - response body type

Parameters:

bodyType - the expected response body type

Returns:

a mono containing the body, or a WebClientResponseException if the status code is 4xx or 5xx

bodyToMono

<T> reactor.core.publisher.Mono<T> bodyToMono(ParameterizedTypeReference<T> typeReference)

Extract the body to a Mono. By default, if the response has status code 4xx or 5xx, the Mono will contain a WebClientException. This can be overridden with onStatus(Predicate, Function).

Type Parameters:

T - response body type

Parameters:

typeReference - a type reference describing the expected response body type

Returns:

a mono containing the body, or a WebClientResponseException if the status code is 4xx or 5xx

bodyToFlux

<T> reactor.core.publisher.Flux<T> bodyToFlux(Class<T> elementType)

Extract the body to a Flux. By default, if the response has status code 4xx or 5xx, the Flux will contain a WebClientException. This can be overridden with onStatus(Predicate, Function).

Type Parameters:

T - the type of elements in the response

Parameters:

elementType - the type of element in the response

Returns:

a flux containing the body, or a WebClientResponseException if the status code is 4xx or 5xx

bodyToFlux

<T> reactor.core.publisher.Flux<T> bodyToFlux(ParameterizedTypeReference<T> typeReference)

Extract the body to a Flux. By default, if the response has status code 4xx or 5xx, the Flux will contain a WebClientException. This can be overridden with onStatus(Predicate, Function).

Type Parameters:

T - the type of elements in the response

Parameters:

typeReference - a type reference describing the expected response body type

Returns:

a flux containing the body, or a WebClientResponseException if the status code is 4xx or 5xx
