The documentation as it states a way of creating Enterprise Integration Patterns using simple messaging between spring applications. When using the Java DSL, there are two options. Ideally, the DSL should offer first class support for all of them, but it is a daunting task to implement all of these and keep up as new adapters are added to Spring Integration. The DSL introduces some fluent builders from which we can easily create a complete a Spring Integration pipeline purely in Java. It accepts a lambda, a SpEL expression, or any AbstractMessageSplitter implementation. Why dsl than xml?
