Answer 1

Does your SaleRoom class implement some interface? If yes, then you should use interface and not class in you code:

ISaleRoom saleRoom = (ISaleRoom) context.getBean(saleName);

Because if your bean implements some interface then Spring by default will create proxy based on this interface.

Here is a good article about proxy creation in Spring.

Also you can change proxying mechanism for Spring AOP if you want to create proxy for target class. This is described here in reference documentation.
