Use Exchange Property in Camel DSL "to"

Question

I want to set a property on a Camel Exchange and then use this property when saving the file. In my camel dsl I have the following: ``` .process(processorToSetExhangeProperty) // sets the property <uid> on the exchange .to("file:/tmp?fileName=file-" + property("uid") + ".xml") ``` The file is being saved as: ``` "file-property{uid}.xml" though ``` My processor is as follows: ``` @Override public void process(Exchange exchange) throws Exception { UUID uuid = UUID.randomUUID(); exchange.setProperty("uid", uuid.toString()); exchange.setOut(exchange.getIn()); } ``` Any thoughts on what may be going wrong or how I can achieve this?

Accepted Answer

The `to` in the Camel is not interpreted at runtime.

You should use recipientList if you want to construct your URI dynamically. See https://camel.apache.org/manual/latest/faq/how-to-use-a-dynamic-uri-in-to.html
