Constructor Detail

BaseHttpInboundEndpoint

public BaseHttpInboundEndpoint(boolean expectReply)

Method Detail

setPayloadExpression

public void setPayloadExpression(Expression payloadExpression)

Specifies a SpEL expression to evaluate in order to generate the Message payload. The EvaluationContext will be populated with an HttpEntity instance as the root object, and it may contain variables:

• #pathVariables
• #requestParams
• #requestAttributes
• #requestHeaders
• #matrixVariables
• #cookies

Parameters:

payloadExpression - The payload expression.

setHeaderExpressions

public void setHeaderExpressions(Map<String,Expression> headerExpressions)

Specifies a Map of SpEL expressions to evaluate in order to generate the Message headers. The keys in the map will be used as the header names. When evaluating the expression, the EvaluationContext will be populated with an HttpEntity instance as the root object, and it may contain variables:

• #pathVariables
• #requestParams
• #requestAttributes
• #requestHeaders
• #matrixVariables
• #cookies

Parameters:

headerExpressions - The header expressions.

setRequestMapping

public void setRequestMapping(RequestMapping requestMapping)

Set the RequestMapping which allows you to specify a flexible RESTFul-mapping for this endpoint.

Parameters:

requestMapping - The request mapping.

getRequestMapping

public final RequestMapping getRequestMapping()

setCrossOrigin

public void setCrossOrigin(CrossOrigin crossOrigin)

Set the CrossOrigin to permit cross origin requests for this endpoint.

Parameters:

crossOrigin - the CrossOrigin config.

Since:

4.2

getCrossOrigin

public CrossOrigin getCrossOrigin()

getPayloadExpression

protected Expression getPayloadExpression()

getHeaderExpressions

protected Map<String,Expression> getHeaderExpressions()

isExpectReply

protected boolean isExpectReply()

Returns:

Whether to expect a reply.

setHeaderMapper

public void setHeaderMapper(HeaderMapper<HttpHeaders> headerMapper)

Set the HeaderMapper to use when mapping between HTTP headers and MessageHeaders.

Parameters:

headerMapper - The header mapper.

getHeaderMapper

protected HeaderMapper<HttpHeaders> getHeaderMapper()

setRequestPayloadTypeClass

public void setRequestPayloadTypeClass(Class<?> requestPayloadType)

Specify the type of payload to be generated when the inbound HTTP 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:

requestPayloadType - The payload type.

setRequestPayloadType

public void setRequestPayloadType(ResolvableType requestPayloadType)

Specify the type of payload to be generated when the inbound HTTP 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:

requestPayloadType - The payload type.

getRequestPayloadType

protected ResolvableType getRequestPayloadType()

setExtractReplyPayload

public void setExtractReplyPayload(boolean extractReplyPayload)

Specify whether only the reply Message's payload should be passed in the response. If this is set to 'false', the entire Message will be used to generate the response. The default is 'true'.

Parameters:

extractReplyPayload - true to extract the reply payload.

getExtractReplyPayload

protected boolean getExtractReplyPayload()

setStatusCodeExpressionString

public void setStatusCodeExpressionString(String statusCodeExpression)

Specify the Expression to resolve a status code for Response to override the default '200 OK' or '500 Internal Server Error' for a timeout.

Parameters:

statusCodeExpression - The status code Expression.

Since:

5.0

See Also:

setStatusCodeExpression(Expression)

setStatusCodeExpression

public void setStatusCodeExpression(Expression statusCodeExpression)

Specify the Expression to resolve a status code for Response to override the default '200 OK' or '500 Internal Server Error' for a timeout.

The statusCodeExpression is applied only for the one-way <http:inbound-channel-adapter/> or when no reply (timeout) is received for a gateway. The <http:inbound-gateway/> (or whenever expectReply is true) resolves an HttpStatus from the HttpHeaders.STATUS_CODE reply Message header.

Parameters:

statusCodeExpression - The status code Expression.

Since:

4.1

MessagingGatewaySupport.setReplyTimeout(long), HttpRequestHandlingEndpointSupport.HttpRequestHandlingEndpointSupport(boolean)

getStatusCodeExpression

protected Expression getStatusCodeExpression()

Parameters:

validator - the Validator to use.

Since:

5.2
