> Annotation-based injection of ServiceContext in Ignite services.
> ----------------------------------------------------------------
>
> Key: IGNITE-15801
> URL: https://issues.apache.org/jira/browse/IGNITE-15801
> Project: Ignite
> Issue Type: Improvement
> Components: managed services
> Reporter: Pavel Pereslegin
> Assignee: Pavel Pereslegin
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Inject ServiceContext using special annotation.
> Suggested approach for Java services:
> _1. Add init/execute/cancel methods without parameters._
> _2. Add default no-op implementations for the new methods (this is required_
> _to preserve compatibility)._
> _3. For old methods that take ServiceContext as a parameter, add default_
> _implementations that delegate to new methods._
> _4. Deprecate the old methods on the API._
> _5. On the implementation level, still use the old methods (again - for_
> _compatibility)._
> _6. Finally, add a @ServiceContextResource annotation to inject_
> _ServiceContext._
> Pros:
> 1. The annotation-based injection is a user-friendly approach widely used in
> Ignite.
> 2. The user does not need to implement all the lifecycle methods every time.
> Cons:
> 1. Duplication of methods in the Service interface for an indefinite period.
> 2. Someday we need to remove the old methods, and this will break all ignite
> services that use the old approach.
