What is AOP in general ?

[Ravi Kiran Va]

Hi ,
New to spring Framework , I am trying to learn this .
This is from a site
In Spring, AOP is a little different than other AOP frameworks in that it brings with it a consistent AOP infrastructure that can be applied for other AOP technical solutions.

I just wanted to know what is AOP in general

In short the intention is to solve cross-cutting concerns (concerns that cut across many functionality).
Examples of cross-cutting concerns are logging, transaction management, security. Some of us just don't want to put similar or nearly identical logging code in 200 methods.

Thanks a lot

Hi ,I just want to add some few words , on this . Logging, transaction management, security are implemented in various technologies but there are differences in implementing one with another, which leads to concern wich to use and whether one can be enhanced to another.

Such concerns are cut down by spring framework, so that it can fit into all persistant technologies, and transaction related issues and as well as security issues

please guide me If I go wrong

I don't think so. We use AOP because we want to separate concerns. For example, business logic, transaction, security are separated concerns, but in traditional programming we have to mix it together.
Using AOP solves this problem, the code looks cleaner, business logic, transaction, security are clearly separated.
