<beans xmlns="http://www.springframework.org/schema/beans"       1.默认命名空间

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        2.xsi标准命名空间，用于指定自定义命名空间的Schema文件

    xmlns:p="http://www.springframework.org/schema/p"            3.声明p命名空间

    xsi:schemaLocation="http://www.springframework.org/schema/beans

         http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">

<bean id="car" class="com.smart.ditype.Car"                      4.id为bean的名称，可以通过getbean("car")获取容器中的Bean，class为Bean的类名

      p:brand="红旗123&amp;CA72"                                  5.采用p命名空间配置Bean属性值

      p:maxSpeed="100"

      p:price="20000.00"/>
