[jira] Created: (CAMEL-3171) Allow property placeholders to be used
anywhere in Spring XML (and blueprint as well)
Allow property placeholders to be used anywhere in Spring XML (and blueprint as well)
-------------------------------------------------------------------------------------
Key: CAMEL-3171
URL: https://issues.apache.org/activemq/browse/CAMEL-3171
Project: Apache Camel
Issue Type: Improvement
Components: camel-blueprint, camel-core, camel-spring
Affects Versions: 2.4.0
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 3.0.0
When using Spring XML or blueprint there is a XSD defining what types the EIP attributes uses.
For example a timeout would be xs:int, and there could be xs:boolean etc.
But you may want to use property placeholders so you can do
{code}
timeout="{{foo.myTimeout}}"
{code}
Where {{foo.myTimeout}} is the properties stuff.

------------------------------------
We could have special type converter which converts from String -> String and detects any property placeholders and does the lookup.
This allows you to use the properties placeholders in any xs:string type in the XSD.

----------------------------------------
Not sure to understand the issue. Is the issue in the xsd (which defines for example xsd:int, so can't be validated) or in the namespace handler?
The only way to fix the xsd would be to relax the schema generation and use strings somehow (i guess there are jaxb2 annotation to enforce the xsd:type to use).
Not sure what the problem / limitations with placeholders you're talking about are.

------------------------------------
Yeah its primary the XSD. Because it will spit our xs:int, xs:boolean etc.
The 2nd objective (we should maybe create a new ticket for that) is to let Camel be able to support property placeholders in any attribute in the XSD.
For example <convertBodyTo charset="{{myCoolCharset}}"/> is not possible today. To support this we need to do this custom on the EIP pattern. Instead it would be nice with a more generic solution.

------------------------------------
Defining the routes in the <routeContext> tag allow us to be in control. Where as inside the <camelContext> we are in the mercy of Spring namespace handler which has some serious limitations in terms of property placeholders resolution.
