WireTap EIP - new message mode - Allow to set headers
-----------------------------------------------------
Key: CAMEL-3857
URL: https://issues.apache.org/jira/browse/CAMEL-3857
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Priority: Minor
Fix For: 2.8.0
If you use wiretap to send a new message to an endpoint, then you can only
provide headers if you use a Processor. However what people would like to do is
to provide headers in the DSL. Usually from XML DSL.
So what you can do now in Java DSL
{code:
.wireTap("direct:tap")
// create the new tap message body and headers
.newExchangeBody(constant("Bye World"))
.newExchangeHeader("id", constant(123))
.newExchangeHeader("date",
simple("${date:now:yyyyMMdd}"))
.end()
{code}
And in XML DSL (has a slight different names for body/header), to reuse the
existing <setHeader> element
{code:xml}
<wireTap uri="direct:tap">
<!-- create the new tap message body and headers -->
<body><constant>Bye World</constant></body>
<setHeader headerName="id"><constant>123</constant></setHeader>
<setHeader
headerName="date"><simple>${date:now:yyyyMMdd}</simple></setHeader>
</wireTap>
{code}
