Additional Camel Quarkus configuration

Quarkiverse Freemarker and its configuration

Camel Quarkus Freemarker uses dev/index.html[Quarkiverse Freemarker] under the hood. This means in particular, that the freemarker.template.Configuration bean produced by Quarkiverse Freemarker is used by Camel Quarkus. The bean can be configured via quarkus.freemarker.* properties - check Freemarker Configuration Reference for more details.

If you wish to use your custom Configuration bean instead of the default provided by Quarkiverse Freemarker, you can let CDI to do the required wiring:

import jakarta.enterprise.context.ApplicationScoped;
import jakarta.enterprise.inject.Produces;
import jakarta.inject.Named;
import freemarker.template.Configuration;
import io.quarkus.arc.Unremovable;
import org.apache.camel.builder.RouteBuilder;

public class MyRoutes extends RouteBuilder {

    Configuration produceFreemarkerConfig() {
        Configuration result = new Configuration();
        return result;

    public void configure() {
