> People using Spring XML as DSL is challenged with the fact they dont have a real programming language under the cover.
> And people do not want to hardcode values/options in the DSL directly. And spring property placeholder support is limited in what it can do.
> So we need for now our own properties component that can load a properties file from classpath. Leverage the spring resource endpoint that can do this.
> And let the simple language be able to access these properties as well so people can use it in expressions
> {code}
> <simple>${propertiesfile:foo:email}</simple>
> {code}
> And the properties file is could be define something like:
> {code}
> <endpoint id="foo" url="propertiesfile://META-INF/myprops.properties"/>
> {code}
> And the file content
> {code}
> email=someone@somewhere.org
> {code}
> Need to think a bit about how to define the properties file. If we can allow you to define it as a url or as a ref.
> For instance the simple expression could be:
> {code}
> <simple>${propertiesfile:classpath://META-INF/myprops.properties:email}</simple>
> {code}
> The above is for quick and dirty.
