Why should I use Spring Integration?
Spring Integration enables lightweight messaging within Spring-based applications and supports integration with external systems via declarative adapters. Those adapters provide a higher-level of abstraction over Spring’s support for remoting, messaging, and scheduling.
What is aggregator in Spring Integration?
Basically a mirror-image of the splitter, the aggregator is a type of message handler that receives multiple messages and combines them into a single message. In fact, an aggregator is often a downstream consumer in a pipeline that includes a splitter.
