Using Apache Camel from Groovy


Apache Camel is an open source integration framework that empowers you to quickly and easily integrate various systems consuming or producing data.

Apache Groovy is a Java-syntax-compatible object-orientedprogramming language for the Java platform. It is both a static and dynamic language with features similar to those of PythonRuby, and Smalltalk. It can be used as both a programming language and a scripting language for the Java Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates seamlessly with other Java code and libraries. Groovy uses a curly-bracket syntax similar to Java’s. Groovy supports closures, multiline strings, and expressions embedded in strings. Much of Groovy’s power lies in its AST transformations, triggered through annotations. [Wikipedia]

Create a file camel-test.groovy like the following


 import org.apache.camel.\*
 import org.apache.camel.impl.\*
 import org.apache.camel.builder.\*
 def camelContext = new DefaultCamelContext()
 camelContext.addRoutes(new RouteBuilder() {
	 def void configure() {
 addShutdownHook{ camelContext.stop() }
 synchronized(this){ this.wait() }

Test it with

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 groovy camel-test.groovy
