【移动应用开发技术】如何在Android环境下支持Spring框架下得AOP，DI，Aspect等

大家都知道，Spring在JavaEE开发中扮演着非常重要的地位。

可以利用它的依赖注入（DI）很好的实现各个模块直接的解耦。

可以利用它的AOP很好的实现面向方面的编程，实现与事务无关的业务逻辑（事务代码写在切面中）

可以使用不同的注解（@Controller；@Service；@Repository）很好的实现分成架构，表明各个模块的作用

可以用MVC实现的Controller很好的处理请求和响应客户端请求

可以轻松的使用集成其他第三方组件实现的功能等。

那这么好的功能，如何能在Android上使用呢，服务于Android开发者呢？

现在给大家推荐一个第三方库，可以很方便的集成到您的应用里面，获取以上这些功能
