What is Spring AOP (Aspect Oriented Programming)?
Spring AOP is a new programming paradigm, which is implemented in pure java and there is no need of special compilation process. It does not need to control the class loader hierarchy, and is thus suitable for use in a Java EE web container or application server. It is another way of thinking about program structure in terms of aspects or concern. If we compare AOP with OOP (Object oriented Programming), the OOP decomposes the application into hierarchy of objects where as the AOP decomposes the application into Aspect or Concern.
