java - Property placeholder doesn't convert

Question

I'm injecting into my route a map where key is a property which is different every time and value which is endpoint where I want to send next my exchange, The problem is that when I'm sending placeholder to get method of map it doesn't convert.

from(REMOVE_FAILED_FILE_FROM_SFTP).routeId(REMOVE_FAILED_FILE_FROM_SFTP_ID)
            .to(buildSftpUri("${body.getFilePath()}", "${exchangeProperty.NetworkName}"))


private String buildSftpUri(String filePath, String network) {
    return format(
            map.get(network),
            filePath
    );

When I'm injecting special case and using it instead of map everything is working

private String buildSftpUri(String filePath, String network) {
    return format(
            sftpUri,
            filePath
    );

Answer 1

The to URI is computed at Camel startup and then statically "baked" into your route. It does not change on runtime.

To use dynamic URIs in a route, you have to use the dynamic TO (.toD) or (as mentioned in the comments) an EIP like Recipient List.
