As you can see Spring Integration posts are going to be continued! This time I would like to share with you small hint of code which will help you to route your message based on existing or not key Signature in your headers.
<int:router id="headerRouter" expression="headers.containsKey('Signature')" default-output-channel="processFurther"> <int:mapping value="false" channel="drop"/> <int:mapping value="true" channel="processFurther"/> </int:router>
