Answer 1

If your bean is an implementation org.apache.camel.Processor, then there is no practical difference. However, using bean bindings gives you more flexibility. Among other things bean

• no need to implement org.apache.camel.Processor
• can offer any number of methods to call
• with arbitrary method signature
• , org.apache.camel.Body org.apache.camel.Header

beans bean .

java DSL .

from("direct:demo").process(new Processor() {
    public void process(Exchange exchange) throws Exception {
        // some stuff
   }
}).to("mock:demoEnd");

:

<route id="sample">
  <from uri="direct:demo"/>
  <process ref="firstProcessor"/>
  <to uri="mock:otherRoute"/>
  <process ref="secondProcessor"/>
  <to uri="mock:endTest"/>
</route>

Vs

<route id="sample">
  <from uri="direct:demo"/>
  <to uri="bean:firstProcessor"/>
  <to uri="mock:otherRoute"/>
  <to uri="bean:secondProcessor"/>
  <to uri="mock:endTest"/>
</route>
