Kishor,

I am looking at your questions, and most of the times there are small little mistakes. Like for example, here is it should be context:component-scan base-package and not context:component-scan basepackage


I would humbly suggest that it might be more effective for you to pay attention to detail before you post. It will not only be faster for you to fix problems, paying attention to detail is ont of the skills that is expected out of every programmer
 
It is sorta covered in the JavaRanch Style Guide.
