Hi @Handler is not related to ConsumerTemplate.
You can use @Handler when you have a POJO with N+ methods, and you just want to tell Camel that it should always use this method when Camel is using this bean, such as when you send a message to the bean endpoint, or use bean(MyBeanClass.class) in the route etc. On the other hand @Consume is an annotation you can use on a bean to let Camel use the method as consumer, and this is more related to consumer template. Then you can do POJO messaging, eg if you use Spring Boot you can do this on beans you let Spring Boot manage. https://github.com/apache/camel/tree/master/examples/camel-example-pojo-messaging On Sun, Jul 7, 2019 at 4:48 PM Richard Flores <[email protected]> wrote: > > Hi, > > I’m new to Camel, trying to get my head wrapped around conventions and usages > and get some samples going.
