Calling an operation from an event listener: how to inject dependencies ?

Antoine_Cordier — Thu, 04 Jun 2015 16:24:22 GMT

Hi,

I need to call the "ExportStructureToFS" operation from an event listener in order to trigger a scheduled export mys documents.

I found this explanation about how to call operations from java code, but I can't get the AutomationService and OperationContext injected as suggested in the example.

I use this declarations:

@Context
protected AutomationService service;

@Context
protected OperationContext context;

Both service and context end being set to null using this technique.

What's wrong ?

Thanks

I've just read about the @context annotation and it seems to precisely be out of context here. If i'm right dependency injection is not available in this case except for unit testing.

Dependency injection via the @context annotation works calling one operation from another.

In that case using:

AutomationService automationService = Framework.getService(AutomationService.class);

To get the service implementation

And

automationService.run(new OperationContext(), "ExportStructureToFS", parameters);

Solved my problem
