Rabbitmq Mule Amqp插件和Mel

我想用路由密钥将邮件发送到exchange。我要发送的消息来自有效负载，但我正在入站属性的消息中设置路由密钥，然后我设置： routingKey=“#[message.inboundProperties.routingKey]”但它不工作

<flow name="ExportToFk" doc:name="ExportToFk">
        <vm:inbound-endpoint exchange-pattern="one-way" path="rabbitSenderVM" doc:name="SendToRabbit"/>
        <scripting:component doc:name="Groovy">
            <scripting:script engine="Groovy"><![CDATA[import org.mule.api.transport.PropertyScope

def xml = payload.xml
def routingKey = payload.routing

println "XML: $xml"
println "ROUTINGKEY: $routingKey"

message.setProperty('routingKey', routingKey, PropertyScope.INBOUND)

return xml]]></scripting:script>
        </scripting:component>
        <amqp:outbound-endpoint exchangeName="${amqp.exchange}" routingKey="#[message.inboundProperties.routingKey]" responseTimeout="10000" connector-ref="AMQP_Connector" doc:name="AMQP"/>
    </flow>
