Apache Camel Java DSL + Spring Integration Hello World Example

In this post we will integrate Apache Camel Java DSL and Spring. In previous Apache Camel Java DSL Example we had written a simple Java DSL route to transfer from one folder to another.
We will now use Spring configuration to call a similar Java DSL route. With this we can take advantage of Spring features like dependency injection, Transaction Management etc.

This tutorial is explained in the below Youtube Video.

Lets Begin

The project structure we would be creating will be as follows-

Apache Camel Java DSL Spring Integration Example

The pom.xml will be as follows-
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">





Create the camel processor as follows-
package com.javainuse.processor;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;

public class MyProcessor implements Processor {

    public void process(Exchange exchange) throws Exception {


Create the SimpleRouteBuilder class that extends RouteBuilder and configures the camel route.
package com.javainuse.route;

import org.apache.camel.builder.RouteBuilder;
import com.javainuse.processor.MyProcessor;

public class SimpleRouteBuilder extends RouteBuilder {

    public void configure() throws Exception {
        from("file:C:/inputFolder?noop=true").process(new MyProcessor()).to("file:C:/outputFolder");

Create the application context that calls the Java DSL RouteBuilder class using the routeBuilder
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring"

	<bean id="routeBuilder" class="com.javainuse.route.SimpleRouteBuilder" />

	<camelContext xmlns="http://camel.apache.org/schema/spring">
		<routeBuilder ref="routeBuilder" />
Finally load the context file to start the Java DSL camel route.
package com.javainuse.main;

import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {

    public static void main(String[] args) {
        AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-camel.xml");
        System.out.println("Application context started");
        try {
            Thread.sleep(5 * 60 * 1000);
        catch (InterruptedException e) {

The files will be copied from inputfolder to the outputfolder.
