type save body() unboxing

[zappee <ar...@gmail.com>]

Hi,

I want to send emails with an smtp endpoint. Source endpoint: message queue.
Source message type: Person.class bean.
I need to read the Person.email parameter somehow at the beginning of my
route and save the value of the email bean parameter for the further
processing. I want to use this value as a "to" parameter of my smtp
endpoint.

I suppose that I can read the bean (which is on the body at the beginning of
my route) via Simple like this: simple("${header.email}"). But if I rename
the email member variable with my IDE (and getter/setter methods are renamed
as well) then my code still correct syntactically because "email" is
referenced as a string and my IDE wont rename this part of my code.

Can I do something like this: setHeader("to",
body().convertTo(Person.class).getEmail()) ?


String emailEndpoint =
"smtp://smtp.gmail.com:587?username=..&password=...&*to=%s*";

from(queueEndpointUrl)
   .log(LoggingLevel.DEBUG, LOGGER, "email sending...")
   .*setHeader("to", simple("${header.email}"))*
   .to("velocity:file:/....)
   .convertBodyTo(String.class)
   .log("Email is ready for send")
   .to( String.format(emailEndpoint, header("to"))
   .log("Email successfully sent");

Thanks for the answer. Honestly I am looking for a simple, "one line"
solution instead of create a new Processor class or Bean or use inline
Processor definition.

Hi zappee,

I think If you want manage some header and class syntactically (compile
time)
you should use Processor feature [1]

from("....").process(new Processor() {
    public void process(Exchange exchange) throws Exception {
        Person payload = exchange.getIn().getBody(Person.class);
        // do something with the payload and/or exchange here
       exchange.getIn().setHeader("to", payload.getEmail());
   }
}).to("....");

Best Regards, Bien à vous,  どうぞお元気で,
