Groovy Camel extensions

The camel-groovy module of Apache Camel extended to accept Groovy closures as arguments to the Camel DSL.

To include camel-groovy, add the following dependency to the pom.xml file:

    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-groovy</artifactId>
        <version>${camel-version}</version>
        <!-- Exclude Groovy bundle in favor of a explicit groovy dependency -->
        <!-- in order to avoid version conflicts -->
        <exclusions>
            <exclusion>
                <groupId>org.codehaus.groovy</groupId>
                <artifactId>groovy-all</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-impl</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Now it is possible to use Groovy closures as argument to Camel processors, filters, transformers, etc.

Some examples:

    // Processor closure
    from('direct:input1')
        .process {exchange ->
            exchange.in.body = exchange.in.body.reverse()
        }
        .to('mock:output')

    // Filter closure
    from('direct:input2')
        .filter {exchange ->
            exchange.in.body == 'blah'
        }
        .to('mock:output')

    // Transform closure
    from('direct:input3')
        .transform {exchange ->
            exchange.in.body.reverse()
        }
