This chapter showcased the simplicity and abstraction that Spring Integration provides when it comes to handling complicated integrations, be it file-based, HTTP, JMS, or any other integration mechanism. Do not panic; I promise that the next few chapters are going to be smaller, and we will cover the testability of Spring Integration, performance, management, and then wrap up with an end-to-end example. In the next chapter, we will cover how Spring Batch and Spring Integration can be integrated to leverage the best of each framework.
