上下文:组件扫描“未绑定

2022-09-01 13:29:40

我是春天的新手,我知道这个问题已经被问过很多次了,但我不得不再问一次。

我猜,我已经做了适当的命名空间声明,但仍然面临错误 这里也有类似的问题,但我没有得到答案"The prefix "context" for element "context:component-scan" is not bound."

这是我的xml文档,是我的命名空间不正确吗?

<?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>

答案 1

将命名空间声明添加到应用程序上下文文件中的标记定义contextbeans

<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">  

答案 2

是的,您必须添加

http://www.springframework.org/schema/context

以前

http://www.springframework.org/schema/context/spring-context-3.0.xsd

所以它看起来像:

<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">
