spring配置文件最全面的详解

转自： http://book.51cto.com/art/201004/193743.htm

此处详细的为我们讲解了spring2.5的实现原理，感觉非常有用

             Spring配置文件是用于指导Spring工厂进行Bean生产、依赖关系注入（装配）及Bean实例分发的”图纸”。Java EE程序员必须学会并灵活应用这份”图纸”准确地表达自己的”生产意图”。Spring配置文件是一个或多个标准的XML文档，applicationContext.xml是Spring的默认配置文件，当容器启动时找不到指定的配置文档时，将会尝试加载这个默认的配置文件。

             下面列举的是一份比较完整的配置文件模板，文档中各XML标签节点的基本用途也给出了详细的解释，这些XML标签节点在后续的知识点中均会用到，熟练掌握了这些XML节点及属性的用途后，为我们动手编写配置文件打下坚实的基础。

下面，就上面的配置列举一个示例：
