In this chapter we have seen the important role of proxies on which all Spring AOP is based. We have seen how to use proxies in a programmatic way and with several implementations (JDK and CGLIB). We have seen how ProxyFactoryBean
simplifies and masks the work of proxies' creation and preparation. Then we saw how to reduce the configuration with the features provided by Spring for the automatic creation of beans with three types of autoproxy. Towards the end of the chapter we glanced at how Spring allows us to act on advised objects and target sources, to enable us to do advanced operations in our code.

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.
