So all that is left is for Step 3 to resolve the <code>channel name</code> ('kermit') to an actual instance of the
<classname>MessageChannel</classname> identified by this name. That will be done via the default
<interface>ChannelResolver</interface> implementation which is a <classname>BeanFactoryChannelResolver</classname>. It
basically does a bean lookup for the name provided. So now all messages which contain the header/value pair as <code>testHeader=kermit</code>

for the name provided. So now all messages which contain the header/value pair as <code>testHeader=kermit</code>
are going to be routed to a <classname>MessageChannel</classname> whose bean name (id) is 'kermit'.
