setChannelName

public void setChannelName(String channelName)

getChannelName

public String getChannelName(Method method)

Returns the channel name to which Messages should be published for this particular method invocation.

Specified by:

getChannelName in class AbstractExpressionSource

setPayloadExpression

public void setPayloadExpression(String payloadExpression)

getPayloadExpression

public String getPayloadExpression(Method method)

Returns the expression string to be evaluated for creating the Message payload.

Specified by:

getPayloadExpression in class AbstractExpressionSource

setHeaderExpressions

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

getHeaderExpressions

public Map<String,String> getHeaderExpressions(Method method)

Returns the map of expression strings to be evaluated for any headers that should be set on the published Message. The keys in the Map are header names, the values are the expression strings.
