Claus Ibsen resolved CAMEL-24917.
---------------------------------
Resolution: Fixed
> camel-yaml-dsl-validator: a to: uri that holds an expression says to use toD:
> -----------------------------------------------------------------------------
>
> Key: CAMEL-24917
> URL: https://issues.apache.org/jira/browse/CAMEL-24917
> Project: Camel
> Issue Type: Improvement
> Components: camel-yaml-dsl
> Reporter: Claus Ibsen
> Priority: Major
>
> From the same benchmark runs: two runs of the http-client rung called
> {noformat}
> http://localhost:8080/stock/$%7Bbody.sku%7D
> {noformat}
> The route used {{to:}} with a uri that holds {{$\{body.sku\}}}. A static
> {{to:}} does not evaluate the expression, so the placeholder is url-encoded
> into the path and every call fails - hundreds of redeliveries before anyone
> reads the log.
> A uri with {{$\{...\}}} in it on {{to:}} is almost always meant to be
> {{toD:}} (or {{toD}} with the uri in {{$\{...\}}}). Proposal: the YAML DSL
> validator says so, so {{camel validate}} and the camel-jbang MCP write/edit
> tools catch it before the route ever runs:
> {noformat}
> to: the uri holds an expression ($\{body.sku\}) but to: sends to a fixed
> endpoint; write toD: to build the uri per message
> {noformat}
> The same check would fit as a startup WARN in core for the cases the
> validator does not see (Java DSL, XML), but the static check is where it pays.
