But the main pieces from a Spring Integration perspective are here. We will however need to create a bean to back our new transformer endpoint. Please see the code download for details.With that, we've established a baseline system. We're injecting the newLeadChannel into the input end of the service activator. It's the pipe by which messages are relayed from one system to another. This will allow us to send the files that are being read from the source folder to multiple destinations. If you don't see it, you might check your SMTP configuration in jetty-env.xml, or else check your spam folder. This is a fertile area for enterprise integration because there are typically multiple systems that need to play nicely together in order to pull the whole thing off. This will allow us to publish to all 3 of the direct channels that we created earlier. We will be needing the basic Spring jars in the classpath. Although JavaBeans helped in the development of user interface (UI) components, they were not able to provide services, such as transaction management and security, which were required for developing robust and secure enterprise applications. LeadGateway.java, a gateway offering access to the messaging system. I will cover following along with code snippet.

The Adapter is an enterprise integration pattern-based component that allows one to “plug-in” to a system or data source. Along with it we will also require Spring Integration jars. We're autowiring the gateway into the @Controller, and we have methods for serving up the empty form and for processing the submitted form. No surprises there.Figure 4 is slightly misleading since it's actually the POJO itself that we're going to call LeadToEmailTransformer; the endpoint is really just a bean adapter that the messaging infrastructure provides so we can place the POJO on the message bus. This isn't an industrial-strength controller as it doesn't do HTTP parameter whitelisting (for example, via an @InitBinder method) and form validation, both of which you would expect from a real implementation. The point of this tier is to orchestrate independent services into meaningful business solutions in a loosely-coupled fashion, which makes it easy to rearrange things in the face of changing business needs.
