public class RSocketInboundGateway
extends MessagingGatewaySupport
implements IntegrationRSocketEndpoint

The MessagingGatewaySupport implementation for the IntegrationRSocketEndpoint. Represents an inbound endpoint for RSocket requests.

May be configured with the AbstractRSocketConnector for mapping registration. Or existing AbstractRSocketConnector bean(s) will perform detection automatically.

An inbound DataBuffer (either single or as a Publisher element) is converted to the target expected type which can be configured by the setRequestElementClass(java.lang.Class<?>) or setRequestElementType(ResolvableType). If it is not configured, then target type is determined by the contentType header: If it is a text, then target type is String, otherwise - byte[].

An inbound Publisher is used as is in the message to send payload. It is a target application responsibility to process that payload any possible way.

A reply payload is encoded to the Flux according a type of the payload or a Publisher element type.

Since:

5.2

Constructor Details

RSocketInboundGateway

public RSocketInboundGateway(String... pathArg)

Instantiate based on the provided path patterns to map this endpoint for incoming RSocket requests.

Parameters:

pathArg - the mapping patterns to use.

Method Details

setRSocketStrategies

public void setRSocketStrategies(RSocketStrategies rsocketStrategies)

Configure an RSocketStrategies instead of a default one. Note: if AbstractRSocketConnector is provided, then its RSocketStrategies have a precedence.

Parameters:

rsocketStrategies - the RSocketStrategies to use.

See Also:

• RSocketStrategies.builder()

setRSocketConnector

public void setRSocketConnector(AbstractRSocketConnector rsocketConnector)

Provide an AbstractRSocketConnector reference for an explicit endpoint mapping.

Parameters:

rsocketConnector - the AbstractRSocketConnector to use.

setInteractionModels

public void setInteractionModels(RSocketInteractionModel... interactionModelsArg)

Configure a set of RSocketInteractionModel this endpoint is mapped onto.

Parameters:

interactionModelsArg - the RSocketInteractionModels for mapping.

Since:

5.2.2

getInteractionModels

public RSocketInteractionModel[] getInteractionModels()

Description copied from interface: IntegrationRSocketEndpoint

Obtain RSocketInteractionModels this ReactiveMessageHandler is going to be mapped onto. Defaults to all the RSocketInteractionModels.

Specified by:

getInteractionModels in interface IntegrationRSocketEndpoint

Returns:

the interaction models for mapping.

getPath

public String[] getPath()

Get an array of the path patterns this endpoint is mapped onto.

Specified by:

getPath in interface IntegrationRSocketEndpoint

Returns:

the mapping path

setRequestElementClass

public void setRequestElementClass(Class<?> requestElementClass)

Specify a type of payload to be generated when the inbound RSocket request content is read by the encoders. By default this value is null which means at runtime any "text" Content-Type will result in String while all others default to byte[].class.

Parameters:

requestElementClass - The payload type.

setRequestElementType

public void setRequestElementType(ResolvableType requestElementType)

Specify the type of payload to be generated when the inbound RSocket request content is read by the converters/encoders. By default, this value is null which means at runtime any "text" Content-Type will result in String while all others default to byte[].class.

Parameters:

requestElementType - The payload type.

setDecodeFluxAsUnit

public void setDecodeFluxAsUnit(boolean decodeFluxAsUnit)

Configure an option to decode an incoming Flux as a single unit or each its event separately. Defaults to false for consistency with Spring Messaging @MessageMapping. The target Flux decoding logic depends on the Decoder selected. For example a StringDecoder requires a new line separator to be present in the stream to indicate a byte buffer end.

Parameters:

decodeFluxAsUnit - decode incoming Flux as a single unit or each event separately.

Since:

5.3

See Also:

• Decoder.decode(Publisher, ResolvableType, MimeType, java.util.Map)

onInit

protected void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class MessagingGatewaySupport

doStart

protected void doStart()

Description copied from class: AbstractEndpoint

Subclasses must implement this method with the start behavior. This method will be invoked while holding the AbstractEndpoint.lifecycleLock.

Overrides:

doStart in class MessagingGatewaySupport

handleMessage

public reactor.core.publisher.Mono<Void> handleMessage(Message<?> requestMessage)

Specified by:

handleMessage in interface ReactiveMessageHandler
