Introduction

This chapter explains how to make use of Camel's built-in EIPs (Enterprise Integration Patterns) to write typical integration logic. Once a message is consumed from an endpoint, you will want to make decisions about what steps should be taken to process it (such as routing), and these EIPs provide you with many different message routing options. The EIPs are used within routes defined by the Camel DSLs (Domain Specific Language).

The EIPs are first class constructs within the DSL. As such, your integration logic will be able to more clearly express how the message is being routed–that is, which EIP is being used. The more you can use these EIP DSL statements within your Camel code, versus doing a lot of routing within custom Java processors, the easier it will be for you and others to understand what the Camel route is doing for future maintenance. This is a key value of Camel, so take full advantage of it within your code, and you will find that you have gained more flexibility...
