For enterprise Java developers, Spring Framework provides remarkable improvements in developer productivity, runtime performance, and overall application quality. Its unique blend of a complete, lightweight container that allows you to build a complex application from loosely-coupled POJOs and a set of easily understood abstractions that simplify construction, testing, and deployment make Spring both powerful and easy-to-use—a hard-to-beat combination. With this power comes the potential for a wide range of uses in both common and not-so-common scenarios. That's where Spring in Practice comes in.
