Replace SpringContext.getBean() with Dependency Injection about openelis-global-2

[mozzy11]

SpringContext.getBean() is used mostly in non beans , ie Classes not handled by Spring.

we can replace it in all Spring beans

Thank you @konavivekramakrishna for creating this issue.
I agree with the suggested changes. On a similar note, we should also consider replacing usages of SpringContext.getBean() with constructor-based injection wherever possible in our codebase.
I will help to review and implement these changes if needed.

@konavivekramakrishna it may make testing a bit easire but it will make the code less readable and more Verbose.

Then as @rahul6603 said should we consider replacing the usage SpringContext.getBean() and modify this issue, @mozzy11 ?
