All Implemented Interfaces:

org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean, MessageHandler

public class XPathSingleChannelRouter
extends AbstractXPathRouter

Router that evaluates the payload using XPathExpression.evaluateAsString(Node) to extract a channel name. The payload is extracted as a node using the provided XmlPayloadConverter with DefaultXmlPayloadConverter being the default.

The provided XPathExpression must evaluate to a non-empty String.
