Spring Framework
维基百科，自由的百科全书
Spring Framework 是一个 Java/Java EE/.NET 的分层应用程序框架。该框架基于 Expert One-on-One Java EE Design and Development（ISBN 0-7645-4385-7）一文中的代码，并最初由 Rod Johnson 和 Juergen Hoeller et al 开发。Spring Framework 提供了一个简易的开发方式，这种开发方式，将避免那些可能致使底层代码变得繁杂混乱的大量的属性文件和帮助类。
Spring 中包含的关键特性：
- 强大的基于 JavaBeans 的采用控制翻转（Inversion of Control，IoC）原则的配置管理，使得应用程序的组建更加快捷简易。
- 数据库事务的一般化抽象层，允许插件式事务管理器，简化事务的划分使之与底层无关。
- JDBC abstraction layer that offers a meaningful exception hierarchy (no more pulling vendor codes out of SQLException), simplifies error handling, and greatly reduces the amount of code programmers need to write. You'll never need to write another 'finally' block to use JDBC again. The JDBC-oriented exceptions comply with Spring's generic DAO (Data Access Object) exception hierarchy.
- 以资源容器，DAO 实现和事务策略等形式与 Hibernate，JDO 和 iBATIS SQL Maps 集成。First-class Hibernate support with lots of IoC convenience features, addressing many typical Hibernate integration issues. All of these comply with Spring's generic transaction and DAO exception hierarchies.
- 灵活的基于核心 Spring 功能的 MVC 网页应用程序框架。开发者通过策略接口将拥有对该框架的高度控制，因而该框架将适应于多种呈现技术，例如 JSP，FreeMarker，Velocity，Tiles，iText 以及 POI。值得注意的是，Spring 中间层可以轻易地结合于任何基于 MVC 框架的网页层，例如 Struts，WebWork，或 Tapestry。
- 提供诸如事务管理等服务的面向方面编程框架。
As MVC patterns (such as Struts) often have difficulty in providing a clear framework for designing the Model part of an application, Spring's ability to work easily with such patterns means that developers can quickly refactor many unsuccessful approaches to make use of Spring's JDBC abstraction layer.
