Now is the time for actual integration! Once the router has routed the message to the appropriate endpoints, it should be processed by them. For example, it can be persisted to a database, sent on a JMS channel, or sent as an e-mail. Depending on the payload type, the router will put the message on to one of the channels jdbcChannel, jmsChannel, or mailChannel. If it cannot understand the payload, it will route it to logChannel. Let's start with the endpoint attached to the channel jdbcChannel that is used for database integration.
