context：component-scan“未绑定

Question

我已经做了适当的命名空间声明，但依然面临着错误 "The prefix "context" for element "context:component-scan" is not bound." 有一个类似的问题在这里，但我力得到答案

这是我的xml文档，是我的名称空间不正确吗？

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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/spring-context-3.0.xsd">



    <bean id="point1" class="org.sri.proj.Point">
        <property name="x" value="0" />
        <property name="y" value="0" />
    </bean>

    <bean id="point2" class="org.sri.proj.Point">
        <property name="x" value="10" />
        <property name="y" value="10" />
    </bean>

    <context:component-scan base-package="org.sri.proj"/>

</beans>

将context名称空间声明添加到beans应用程序上下文文件中的标记定义中

<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"
    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">
