Simple Expression in apache-camel uri

问题

I'm new to apache-camel and know i met a problem. I want to use simple expressions in my uri definition, but i don't know how.

For example:

from("foo://bar").to("foo://bar?var=${header.varName}");

Is there a way to use such expressions?

Use the Recipient List EIP pattern, which allows you to compute the dynamic URI using an Expression. For example using the Simple expression language as shown below:

recipientList(simple("freemarker://templateHome/${body.templateName}.ftl"))

Another way is to use the "CamelXsltResourceUri" property in the header.

.setHeader("CamelXsltResourceUri",simple("xslt:<path>/<to>/<template>"))

"recipientList(simple("freemarker://templateHome/${body.templateName}.ftl"))"

The selected answer did not work for me since I had to use a custom uriresolver
