Apache Camel is a rule-based routing and mediation engine that provides the Enterprise Integration Patterns using an API or declarative Java domain-specific language to configure routing and mediation rules.
In this recipe, we will use the Java Camel library. So, you need to add the org.apache.camel/camel-core
to your project.clj
:
(defproject chapter04 "0.1.0" :dependencies [[org.clojure/clojure "1.8.0"] [org.apache.camel/camel-core "2.16.1"]
Here, we will learn basic uses of Camel from Clojure.
The following code imports the Camel classes that we will use:
(ns chapter04.camel (:import [org.apache.camel.impl DefaultCamelContext] [org.apache.camel.builder RouteBuilder] [org.apache.camel.main Main] [org.apache.camel Exchange] [org.apache.camel Processor] ))
