Add Apache Camel to the list of applications

Apache Camel 2.17 ships with spring-boot support, and is able to work with the initializer project, so it can be listed in the choices.

There is some more details here https://github.com/spring-projects/spring-boot/pull/5426#issuecomment-197341210

And from the Camel website at http://camel.apache.org/spring-boot

What Camel 2.17 brings to the table is a camel-spring-boot-starter module that is similar to the other starter modules. So end users can just add this dependency and have Apache Camel enabled.

Then Camel routes can be created and automatic started by Camel such as adding java code as follows:

package com.example;

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;

@Component
public class MyRoutes extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("timer:foo")
            .setBody().constant("Hello Spring")
            .to("log:foo");
    }
}

Which when you run mvn spring-boot:run is starting Camel with the route:

I apologize again for continuing my comment. This is what happens when engineers got together without politics. 😃

It’s refreshing to see that Apache Camel is there along with Spring Integration in the choices. It just feels good. Back in the FuseSource days this would’ve been cool so now with Camel being a Red Hat project it’s even more awesome to see this happening (I also very much appreciate that Spring Boot has Undertow starter). Thanks @davsclaus for working on such an excellent software and making it easier and more accessible to Spring Boot projects and thanks @snicoll for making such collaboration possible. 👍
