Hello, I'm using Camel 2.23.1 to create camel based application.
I use velocity component of camel. My requirement is to somehow override template reading logic, so I can inject a template from DB if it's defined and if not - use a file, the usual way. Also, the camel velocity cache should be used to speed things up, so the injection should be pretty high in the call tree. I've decided to try to use the functionality of overriding VelocityEngine as described here: https://github.com/apache/camel/blob/master/components/camel-velocity/src/main/docs/velocity-component.adoc So I've added this into the properties file: camel: component: velocity: velocity-engine: pl.altkom.software.dpc.camelrider.cc.module.dpc.dpcapi.route.VelocityEngineTest And I've created this VelocityEngine implementation: ============================================= package pl.altkom.software.dpc.camelrider.cc.module.dpc.dpcapi.route; import org.apache.velocity.Template; import org.apache.velocity.app.VelocityEngine; import org.apache.velocity.exception.ParseErrorException; import org.apache.velocity.exception.ResourceNotFoundException; import lombok.extern.slf4j.Slf4j; @Slf4j public class VelocityEngineTest extends VelocityEngine { @Override public Template getTemplate(String name) throws ResourceNotFoundException, ParseErrorException { log.error("TEST"); return super.getTemplate(name); } @Override public Template getTemplate(String name, String encoding) throws ResourceNotFoundException, ParseErrorException { log.error("TEST"); return super.getTemplate(name, encoding); } } ========================================================= Unfortunately, the test message isn't shown. I've done some more tests, and the class is not used by camel. I tried to search the source code of camel to find this property and figure out how to properly use it. It seems as it's not used by camel to initialize the velocity engine:( Am I wrong? Is it a bug or I just can't properly use it? Can you guys help me use it properly? Or maybe can you guide me on how to do the thing I want to do some other way? I'll be very grateful. Piotr Kaczmarski
