A few years back, Spring arrived as is a fresh breeze blowing over the Java landscape. Based on the principles of dependency injection, interface-oriented design, and aspect-oriented programming, Spring combines enterprise application power with the simplicity of plain-old Java objects (POJOs). Now, Spring has grown into a full suite of technologies, including dedicated projects for integration, OSGI-based development, and more. Spring in Action, Third Edition has been completely revised to reflect the latest features, tools, practices Spring offers to java developers. It begins by introducing the core concepts of Spring and then quickly launches into a hands-on exploration of the framework. Combining short code snippets and an ongoing example developed throughout the book, it shows you how to build simple and efficient J2EE applications. Inside, you'll see how to: Solve persistence problems Handle asynchronous messaging Create and consume remote services Build web applications Integrate with most popular web frameworks In short, you'll learn how to use Spring to write simpler, easier to maintain code so that you can focus on what really matters your critical business needs. The revised Third Edition explores the core Spring Framework issues, as well as the latest updates to other Spring portfolio projects such as Spring WebFlow and Spring Security. The result is a book that's both broader and deeper than previous editions. You'll learn the full range of new features available with Spring 3, including: More annotation-oriented options to reduce the amount of XML configuration Full-featured support for REST A new Spring Expression Language (SpEL) that makes short work of wiring complex values. Examples that illustrate the current best practices developed in the Spring community. This book assumes that you know your way around Java, but no previous experience with Spring is required.
