Routers are components that pick messages from a channel and, depending on a set of pre-defined criteria, deliver them to different channels. Routers never change the message—they only route/reroute messages to the next destination. Spring Integration provides the following built-in routers:
Payload-type router

<int:payload-type-router input-channel="transformedChannel"> <int:mapping type="com.cpandey.siexample.pojo.SoFeed" channel="jdbcChannel" /> <int:mapping type="java.lang.String" channel="jmsChannel" /> <int:mapping type="org.springframework...
