找不到元素'context:annotation-config'的声明 [英] no declaration can be found for element 'context:annotation-config'

问题描述

在春天，每当我在spring.xml中写入<context:annotation-config/>时，都会出现此错误:-

in spring whenever i write <context:annotation-config/> in my spring.xml i get this error:-

线程主"中的异常org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:来自类路径资源[spring.xml]的XML文档中的第81行无效；嵌套的异常是org.xml.sax.SAXParseException; lineNumber:81; columnNumber:30； cvc-complex-type.2.4.c:匹配的通配符很严格，但是找不到元素'context:annotation-config'的声明.

Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 81 in XML document from class path resource [spring.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 81; columnNumber: 30; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:annotation-config'.

而我的spring.xml的内容是

And the content of my spring.xml is

<?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-4.0.xsd"
xmlns:context="http://www.springframework.org/schema/context"
>

<bean id="circle" class="com.mysite.Circle">
</bean>

 ...

<context:annotation-config/>

谁能告诉我我要去哪里错了吗??

Would anyone please tell me where am i going wrong ????

推荐答案

您正在使用XML命名空间(在这种情况下为上下文)而未声明

You are using an XML namespace (in this case context) without declaring it

将您的xml更改为此:

Change your xml to this:

<?xml version="1.0" encoding="UTF-8"?>
<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-3.1.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.1.xsd">

您还引用了 http://www.springframework.org/schema/beans/spring -beans-4.0.xsd ，我认为它不存在.

You were also referencing http://www.springframework.org/schema/beans/spring-beans-4.0.xsd, which I don't think exists.
