通过配置xml文件的方式将Classpath下的类交给Sping容器管理

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
<span style="white-space:pre">	</span>xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
	<context:component-scan base-package="包名"/>
</beans>

注意：报名不一定是完整的包名，例如所有的包名以com开头，则通过以下配置可以将所有的类让Spring容器管理<context:component-scan base-package="com"/
