-------------------------------------------
> Create a DataSourceResourceLoader that can be wired to the datasource with IoC
> ------------------------------------------------------------------------------
>
> Key: VELOCITY-267
> URL: https://issues.apache.org/jira/browse/VELOCITY-267
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.5
> Environment: Operating System: other
> Platform: Other
> Reporter: Matt Raible
> Priority: Minor
> Fix For: 1.5
>
> Attachments: DatabaseResourceLoader.java, resource_ioc.patch,
> resourceinstance.zip
>
>
> I'd like to create a ResourceLoader similar to DataSourceResourceLoader,
> except that I'd like to set
> the DataSource via IoC (in Spring). The main reason for this is so my
> database-loading of templates
> does not depend on a JNDI connection.
> The main problem is how to manage a ResourceLoader with Spring and then set
> it declaratively on its
> VelocityEngine - rather than via properties.
> <suggested patch from Will Glass-Husain>
> Does this mean that you'd need to pass in an instance of a resource manager
> (initialized with the datasource) to VelocityEngine, rather than just set
> the class name as a property? (MR - Yes)
> As I understand the source code, this doesn't seem possible. But I think a
> patch wouldn't be difficult. (a change to
> RuntimeInstance.initializeResourceManager) to look for an instance of the
> class as well as the class name. Something similar to
> LogManager.createLogSystem which accepts as a property the class name of a
> class that implements LogSystem, or an instance of the class itself.
> </suggested patch>
