HTTP POST body - simple transformer?

[davison]

hi,

I'm trying to transform an x-www-form-urlencoded POST body to a JMS message. The POST parameters contain both the destination name and the payload. I'm using SI 2.1.0 so that I have dynamic destination expression available on the outbound-channel-adapter.

Example POST body might look like this. The 'body' param should become the message payload.

 queue=TESTQUEUE&body=<foo>hello world</foo>

I'm hoping I can somehow do this with SpEL rather than writing transformer classes..

    <int-http:inbound-channel-adapter 
        id="httpIn" 
        channel="httpRcvdChannel"
        name="/tojms"
        supported-methods="POST"
        />
    <int:channel id="httpRcvdChannel"/>
    
    <!-- what goes in the expression attribute?? -->
    <int:transformer
        input-channel="httpRcvdChannel"
        output-channel="jmsOutChannel"
        expression="payload"  
        />
    
    <int-jms:outbound-channel-adapter 
        id="jmsOut"
        destination-expression="header.queue"
        channel="jmsOutChannel"
        />
    <int:channel id="jmsOutChannel"/>

What's the simplest way to do the transformation?

Hello.

Try this:

<chain  input-channel="httpRcvdChannel"  output-channel="jmsOutChannel">
	<transformer expression="payload.toSingleValueMap()"/>
	<header-enricher>
		<header name="queue" value="payload.queue"/>
	</header-enricher>
	<transformer expression="payload.body"/>
</chain>
