近日由于业务需要，接触了一些Flex下的东西，比如Mate框架（一个集成MVC和IOC的框架，其事件广播机制很强大），疏于整理spring.net学习资料，现在终于得闲，将心得梳理一下：
spring.net是java下大名鼎鼎的spring框架移植到.net的开源项目，且借助于.net强大的反射机制，甚至拥有比原java版本更强大的功能。
那它能用来做什么呢？核心功能就是IOC和AOP：
IOC（Inversion of Control），字面意思为“反转控制”，我更倾向于理解为“依赖注入”，意思就是说：在基于接口开发的情况下，我们会对需要的业务处理对象（数据访问，业务逻辑等）一一做上接口，前端使用时只是对接口的调用，而并不关心具体是什么类具体去实现了这个接口~听起来似乎不可能，是的，如果没有IOC，这是不可能的事情，我们的前端逻辑和后端实现是紧紧耦合的，做页面开发的人必须知道哪一个类（.cs文件）拥有哪些方法，即便是基于接口，我们也依然要在程序里去实例化它，形如：

无形中，基于接口开发成了鸡肋，前端开发人员几乎要知道一条龙的编码流程才能做业务开发！（当然，有的项目就是一个人在做）
好吧，那就使用IOC，它是怎么解开这个耦合关系的？
IOC框架一般会维护一个配置文件，它大概要完成的使命是：
1、将实现接口的对象进行列表，表示它们是被页面需要的；
2、把页面的以基于URL的形式进行列表，表示它们是需求方。
余下的事情，是框架来进行协调，在页面上声明一下某一个接口的对象，在它需要实例化时，IOC框架会自动将对应的接口实现进行注入。如下就是一个Spring.net的配置范例片断：

如果是初次接触IOC，可能理解起来会有些生涩，毕竟是个基于配置的框架，有些东西需要深入了解，这个以后可以一步步探个究竟。OK，接着就是AOP。
那么AOP又是做什么的呢？Aspect Oriented Programming，字面意思即为“面向切面的编程”。Aspect，就是切面，代表了我们很多项目中重复开发的模块，如邮件功能，日志功能等。
说起来是会让人很颓废的，我们花费在重复劳动上的时间，有时太多了。这个项目写日志，下一个还写日志，日志有区别吗？答案是没有，但它就是需要，哪怕是复制粘贴，还是需要！被需要当然是好事，说明它存在的价值，但能否把这样的东西做成一个组件，以后拿来就用，并且与新的项目系统人我两不犯，无缝集成？
当然是可以的，AOP在此时的价值会得到充分的体现。就我个人而言，对它的理解，更多的是一个监听器，侦测你的业务是否有相关的需要，只要你有需要发出，AOP框架就会在你需要的地方设一个断点，进行功能模块的切入，让它去做你希望它做的事。就这么神奇~
这里放出一个代码片断，小小注解一下以上比较让人头晕的概念：

这一代码片断实现的功能是：如果发现系统中新增了一个用户（即User的业务管理器调用了Save方法），那么在日志系统中，存储一下用户名，让管理员可以在翻日志时知道谁又加入了~
当然，就这么一段代码并不能完成这个监控功能，同样的，我们必须做配置（Spring.net把开发提高到了对配置进行管理的境地，你在配置管理上花的时间，将大于以往，好处是更关注和贴近业务而不是代码），告诉AOP框架，我们希望监听哪些对象的哪些动作，以及监听到后我们要调用哪些模块来采取行动：

也许这样的配置片断更让人犯晕，没关系，习惯了就好，有些事情需要我们自己去做（DB，ENTITY，DAO，BLL开发），有些事情需要的是我们去理解（AOP框架，通知，切面，代理对象），相信不需要多长时间，这些都不是问题。
关于IOC和AOP，以上只是寥寥几笔带过，在以后的实例系列中，将各个击破
实例主要围绕的是一个音乐网站的搭建（有点儿像AllMusic内样的，而不同于别的什么无聊SNS社区），会涉及的内容是：Spring.net、nHibernate、codeSmith模板、多对多表结构、Castle MonoRail（虽然有人强建不建议把MonoRail集成到Spring.net中，但我至今没找到.net 2.0下好的MVC解决方案，用用MonoRail有助于更好理解MVC，优化性能）。
