             Summary: Route Template local beans 
                 Key: CAMEL-16394
                 URL: https://issues.apache.org/jira/browse/CAMEL-16394
             Project: Camel
          Issue Type: New Feature
          Components: camel-core
            Reporter: Luca Burgazzoli
             Fix For: 3.x


Now that we have route templates and kamelets, we should explore the option to 
have route local beans in addition to route local properties. This would be 
very useful when dealing with EIPs or endpoints that require specific beans.

As example, assuming I have the following template:

{code:java}
routeTemplate()
  .from("direct:start")
  .to("aws2-s3:...?amazonS3Client=#myClient")
{code}

Then myClient need to be created at global scope and there's no way to create 
one that is specific for the template.

We should provide something like:

{code:java}
routeTemplate()
    .templateParameter("region")
    .templateParameter("bucket")
    .configure((RouteTemplateContext context) -> { 
        context.bind(
            "myClient", 
            S3Client.builder().region(context.getProperty("region")).build()
        );
    })
    .from("direct:start")
    .to("aws2-s3:{{bucket}}?amazonS3Client=#myClient")
{code}

So when the route is materialized, the configure method is invoked, the 
myClient bean is registered to the current template context and retrieved by 
the reifier to materialize the route.
