Injecting from application.yml in camel processor

I'm trying to inject values from the application.properties file in a camel processor but it returns null. I also tried adding the @Component annotation but this breaks the application.

public class MyProcessor implements Processor {
 @Value("${myProperty.path}")
  public String path;
  public void process(Exchange exchange) throws Exception {
        System.out.println(path);
    }
}

I'm new to both camel and spring. What could I do to read properties from the application.properties file in the processor class?

Property injection with @Value only works with container managed beans.

Therefore, you are on the right track with @Component, but I suspect (as mentioned in the comments) that your MyProcessor is not such a bean.

If you do one of these in your Camel route, then your Processor is NOT such a bean.

.process(MyProcessor.class)
.process(new MyProcessor())

Instead you have to annotate your Processor with @Component, hold an instance variable of it in your Camel Route class and then reference the instance.

.process(myProcessorInstance) <-- variable
