Spring致力于J2EE应用的各层的解决方案，而不是仅仅专注于某一层的方案。可以说Spring是企业应用开发的“一站式”选择，并贯穿表现层、业务层及持久层。然而，Spring并不想取代那些已有的框架，而是与它们无缝地整合。-Spring is committed to the layers of J2EE applications solutions rather than just focus on a particular layer of the program. Can be said that Spring is the enterprise application development of " one-stop"　choice, and through the presentation layer, business layer and persistence layer. However, Spring does not want to replace those existing framework, but with their seamless integration.
