Bertrand Delacretaz created SLING-3342:
------------------------------------------
Summary: Do not use SlingBindings in Java code
Key: SLING-3342
URL: https://issues.apache.org/jira/browse/SLING-3342
Project: Sling
Issue Type: Task
Components: Best practices
Reporter: Bertrand Delacretaz
Assignee: Bertrand Delacretaz
Priority: Minor
**DRAFT** - to be reviewed, and we need to update the SlingBindings javadocs as
well.
SlingBindings is meant to be used in Sling scripts.
It might be available as a Request attribute in some cases, as Sling sets that
before running scripts, but one cannot rely on that in java code.
There’s usually no reason to use it in Java code anyway, all the services that
it provides are available directly, for example via an @Reference annotation.
Here’s a typical counter-example which should use an @Reference to the FooBar
service instead:
// Do NOT do that!
SlingBindings bindings
(SlingBindings)request.getAttribute(SlingBindings.class.getName());
SlingScriptHelper scriptHelper = bindings.getSling();
FooBar fb = scriptHelper.getService(FoorBar.class);
