传统的xml属性配置

<bean name="dengyi" class="...">
    <property name="name" value="Dengyi"/>
    <property name="age" value="18"/>
</bean>

等价于

使用p命名空间配置

<bean name="dengyiyi" class="..."
    p:name="Dengyi" p:age="18"/>

传统的xml构造器配置

<bean name="dengyi" class="...">
    <constructor-arg index="0" value="dengyi3"/>
    <constructor-arg index="1" value="18"/>
</bean>

等价于

使用c命令空间配置

<bean name="dengyiyi" class="..."
    c:name="dengyiyi" c:age="18">
