Advice - specifies what to do at a join point. In the case of Spring, this is the additional behavior that Spring will inject around a method invocation. It is most often defined in a method interceptor, which will be invoked as part of an interceptor chain wrapping the method invocation.
The key to AOP is providing a different way of thinking about application structure.
This structural thinking is captured in the form of pointcuts. Pointcuts are predicates determining which joinpoints a piece of advice should apply to. It's more intuitive â although not entirely accurate â to think of a pointcut as a set of joinpoints: for example, a set of methods that might be targeted by an advice.
These two books from Wrox, are a good starting point - it's hard to understand these terms and/or their logic without understanding the Spring approach.

Object oriented programming has become mainstream over the last years, having almost completely replaced the procedural approach. One of the biggest advantages of object orientation is that a software system can be seen as being built of a collection of discrete classes. Each of these classes has a well defined task, its responsibilities are clearly defined.
