本书深入剖析了当前流行的轻量级开发框架Spring技术。本书总共分成3部分。第一部分，重点阐述Spring的架构。这部分内容循序渐进带领开发者进 入Spring中。主要在于阐述Spring IoC和Spring AOP。第二部分，重点阐述Spring的使用。这部分内容从简化Java/J2EE的角度出发，从J2EE平台各个技术层面分析、并给出大量的研究实 例，对Spring提供的API进行阐述。主要在于阐述Spring对J2EE API提供的服务抽象。第三部分，重点阐述Spring高级专题。这部分内容重点对视图技术进行了研究，因为对于开发Web应用而言，前端界面的开发往往 工作量很大。因此，使用合理的视图技术开发Web应用对于项目的成功与否很关键。另外，Web应用的安全性往往也是企业应用中最为重要的需求之一，而用于 Spring的Acegi安全框架很好地解决了这个问题，这也是第三部分重点研究的内容之一。-This book analyzes in depth the popular Spring fr a mework for lightweight development technologies. This book is divided into 3 parts total. The first part focuses on the Spring fr a mework. This part of the step by step into the Spring of leading developers. Spring IoC and mainly describes Spring AOP. The second part focuses on the use of Spring. This part of the content from the perspective of Java/J2EE simplified, from the various technical aspects of J2EE platform, and gives a lot of examples provided on the Spring API to elaborate. Spring is on the major J2EE API describes the services provided by the abstract. The third part focuses on the Spring advanced topics. This section focuses on the view of technology studies, as for the development of Web applications, front-end interface development is often a lot of work. Therefore, the use of reasonable view of technology development for Web applications is the key to the success of the project. In addition, Web application security is a
