Claus Ibsen updated CAMEL-8723:
-------------------------------
Fix Version/s: (was: 2.16.0)
2.17.0
> Add desired message type to ProducerTemplate.sendBody methods
> -------------------------------------------------------------
>
> Key: CAMEL-8723
> URL: https://issues.apache.org/jira/browse/CAMEL-8723
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Affects Versions: 2.15.1
> Reporter: Geert Schuring
> Labels: pojo, type-converter
> Fix For: 3.0.0, 2.17.0
>
> Attachments: camel-8723.patch
>
>
> Using Pojo Messaging annotations, Camel automatically uses the Type Converter
> system to unmarshall XML messages to JAXB objects in the following scenario:
> {code:java}
> public class CamelPojoDemo {
>
> @Produce(uri = "amq:camelpojodemo.reply")
> private ProducerTemplate producer;
>
> @Consume(uri = "amq:camelpojodemo.request")
> public void trigger(UpdateMarketDataMessage message) {
> String result = "Processed prices: " +
> message.getMarketData().getPrices().size();
> producer.sendBody(result);
> }
> }
> {code}
> However, handing the producer a JAXB object and expecting it to marshall it
> to XML before sending it does not seem possible in the current API.
> I would like to propose to add the following method to the ProducerTemplate:
> {code}
> /**
> * Sends the body to the default endpoint after converting it to the
> given type
> * <br/><br/>
> * <p/><b>Notice:</b> that if the processing of the exchange failed with
> an Exception
> * it is thrown from this method as a {@link
> org.apache.camel.CamelExecutionException} with
> * the caused exception wrapped.
> *
> * @param body the payload to send
> * @param type the type which the body should be converted to before
> sending
> * @throws CamelExecutionException if the processing of the exchange
> failed
> */
> void sendBody(Object body, Class type) throws CamelExecutionException;
> {code}
> This would allow users to send a JAXB object and instruct Camel to use its
> Type Converter system to marshall the object to XML:
> {code}
> producer.sendBody(jaxbObject, String.class);
> {code}
> Note: The sendBody, sendBodyAndHeader and sendBodyAndProperty methods are all
> overloaded several times which could mean quite a number of new methods.
