Major Description
The $simple{} syntax is useful to avoid clash with spring property placeholders. The camel-sql component does not recognize it, so when users create endpoints like:
<to id="_to1" uri="sql:select * from accounts where customerid = :#${header.xxx}?dataSource=dataSource"/>
I.e. use the id field and the "${header.xxx}" syntax, spring tries to find a property named "header.xxx" and crashes.
We should allow writing:
<to id="_to1" uri="sql:select * from accounts where customerid = :#$simple{header.xxx}?dataSource=dataSource"/>
