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 used AOP and IoC with Spring to create in a minimal way an application with DDD Test Driver Development.

We've seen what DDD is and what its philosophy is, and how it can be applied using AOP and Spring to use IoC on domain objects instantiated outside Spring using AspectJ's weaver.

We've seen how to adopt Aspects to improve implementation by centralizing the logic of crosscutting functionalities among classes.

We've improved the application's speed, avoiding calls to the database in a transparent way, which without AOP would have been unavoidable for the application layer.

We've also employed AOP for the authorization part with Spring Security.

As an exercise, the reader will be able to apply the other aspects described in the previous chapters as well, which we left out for the sake of brevity in this partial application.

We've used JUnit, DbUnit, Spring, and SpringIDE AJDT in Eclipse.

In the next chapter will see in detail how to install the whole development environment...
