Spring 2.5 Aspect Oriented Programming

Overview of this book

Developing powerful web applications with clean, manageable code makes the maintenance process much easier. Aspect-Oriented Programming (AOP) is the easiest and quickest way to achieve such results. Spring is the only Java framework to offer AOP features. The combined power of Spring and AOP gives a powerful and flexible platform to develop and maintain feature-rich web applications quickly. This book will help you to write clean, manageable code for your Java applications quickly, utilizing the combined power of Spring and AOP. You will master the concepts of AOP by developing several real-life AOP-based applications with the Spring Framework, implementing the basic components of Spring AOP: Advice, Joinpoint, Pointcut, and Advisor. This book will teach you everything you need to know to use AOP with Spring. It starts by explaining the AOP features of Spring and then moves ahead with configuring Spring AOP and using its core classes, with lot of examples. It moves on to explain the AspectJ support in Spring. Then you will develop a three-layered example web application designed with Domain-Driven Design (DDD) and built with Test-Driven Development methodology using the full potential of AOP for security, concurrency, caching, and transactions.

Summary


In this chapter we've seen how to implement crosscutting functionalities, such as concurrency control, the employment of a cache, and security management. Without AOP those functionalities would be scattered across the application, with the same code duplicated in different modules. With AOP we can have cleaner code, much more concise and easier to maintain and debug. We've seen how it is possible to implement these functionalities without having tangled or scattered code, implementing functionalities with aspects and advices.

Other important functionalities are transactions management, application logging, exception management, layout, and others. They will be illustrated in the next two chapters in a complete and working application.
