| Aspect-oriented programming (AOP) is a programming paradigm that was defined at the
Xerox Palo Alto Research Center (PARC) in the mid-1990s. The roots of this paradigm can be
traced back to several works designed to improve code modularity and facilitate reuse and
maintenance.
The benefits of AOP for modularizing code have drawn attention from many application
developers, especially those in the domain of web applications. Indeed, AOP is an excellent
complement to Internet-oriented application servers such as Sun Microsystems’s J2EE or
Microsoft’s .NET. With AOP, developers can facilitate the development and boost the productivity
of these types of applications. However, AOP is not limited to the domain of web-centric
applications. Similar to other programming paradigms (such as objects), AOP is a general technique
that can be applied to any kind of application.
This book defines and explains the concepts of AOP. The implementation of these
concepts is illustrated by a presentation of four major existing AOP products (AspectJ, JAC,
JBoss AOP, and Spring AOP). In addition, this book shows how you can use AOP for programming
J2EE applications. |
