This book adopts a unique approach to helping enterprise Java developers learn Spring 4 fast. Rather than filled with disjointed, piecemeal samples to show Spring features one at a time, it is designed to base your total Spring learning experience on a functioning, end-to-end integrated sample named SOBA (Secure Online Banking Application), which runs on any one of the three operating systems (Windows, Linux and Mac OS X), any one of the four Java App Servers (Tomcat, GlassFish, JBoss and WebLogic), and any one of the four RDBMS (MySQL, PostgreSQL, Oracle and SQL Server). The book also includes another standalone sample application named MyNotes, which is simpler than SOBA. Specifically, this book helps you learn the following latest Spring technologies: * Spring Core Framework * Spring MVC Web Framework * Spring Data Access Framework (JDBC and Hibernate) * Spring RESTful Web Services Framework * Spring Security Framework * Spring Transaction Management Framework * Spring Validation Framework * Spring Aspect Oriented Programming (AOP) Framework * Spring Testing * Spring Integration with EJB * Spring Web Flow Framework At the end of your learning experience with this book, you will gain truly applicable skills and will be able to start contributing to the success of your Spring-based enterprise application project immediately.
