因为这是个基于spring的web应用，所以当然我们从web.xml看起：

在第23-25行表示了我们进入spring框架，这个大家都知道。
在第11-16行，定义了Spring的配置文件，我当时设计时候，还是采用了多配置文件结构，所以在应用层，我只指定了这1个配置文件，这个配置文件定义了Spring应用的一些宏观的内容：
这个文件在/WEB-INF/config/applicatino-config.xml中：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" > <!-- Activates annotation-based bean configuration --> <context:annotation-config /> <!-- Scans for application @Components to deploy to spring container --> <context:component-scan base-package="xx.xx.xx.handlers" /> <context:component-scan base-package="xx.xx.xx.service.impl" /> <context:component-scan base-package="xx.xx.xx.portlet" /> </beans>
我这里只开启了注解配置，并且启用了java包扫描，所以被我罗列的包中的所有Spring注解都会被扫描到，并且在Spring Application Context加载时自动实例化对应的被标注的 bean.
