Chapter 8. Spring Integration

In this chapter, you will learn the principles behind enterprise application integration, used by many modern applications to decouple dependencies between components. The Spring framework provides a powerful and extensible framework called Spring Integration, which provides the same level of decoupling to enterprise applications and data that the core Spring framework provides to components within an application.

This chapter aims to give you all the required knowledge to understand the patterns involved in enterprise application integration (EAI), what an enterprise service bus (ESB) is, and how to build solutions using Spring Integration.

Upon finishing this chapter, you will be able to write fairly sophisticated ...
