Apache Camel 是一個非常強大的基於規則的路由以及媒介引擎，該引擎提供了一個基於POJO的 企業應用模式(Enterprise Integration Patterns)的實現，你可以採用其異常強大且十分易用的API (可以說是一種Java的領域定義語言 Domain Specific Language)來配置其路由或者中介的規則。 通過這種領域定義語言，你可以在你的IDE中用簡單的Java Code就可以寫出一個類型安全並具有一定智能的規則描述文件。這與那種複雜的XML配置相比極大簡化了規則定義開發。 當然Apache Camel也提供了一個對Spring 配置文件的支持。
Apache Camel 採用URI來描述各種組件，這樣你可以很方便地與各種傳輸或者消息模塊進行交互，其中包含的模塊有 HTTP, ActiveMQ, JMS, JBI, SCA, MINA or CXF Bus API。 這些模塊是採用可插拔的方式進行工作的。Apache Camel的核心十分小巧你可以很容易地將其集成在各種Java應用中。
Book DescriptionApache Camel is a Java framework that lets you implement the standard enterprise integration patterns in a few lines of code. With a concise but sophisticated DSL you snap integration logic into your app, Lego-style, using Java, XML, or Scala. Camel supports over 80 common transports such as HTTP, REST, JMS, and Web Services.
Camel in Action is a Camel tutorial full of small examples showing how to work with the integration patterns. It starts with core concepts like sending, receiving, routing, and transforming data. It then shows you the entire lifecycle and goes in depth on how to test, deal with errors, scale, deploy, and even monitor your app— details you can find only in the Camel code itself. Written by the developers of Camel, this book distills their experience and practical insights so that you can tackle integration tasks like a pro.
