Question

我有一个dispatcher-servlet.xml和一个applicationContext.xml。

我一直在做一些重构，并且已经移动了

<mvc:annotation-driven/>
<context:component-scan base-package="com.xxx"/>

从dispatcher-servlet.xml到applicationContext.xml。

我现在收到此错误：

2012-01-26 10:34:36.434:WARN::Nested in org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 11 in XML document from ServletContext resource [/WEB-INF/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.:
org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.

我的applicationContext.xml如下所示：

    <?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:p="http://www.springframework.org/schema/p"
       xmlns:ehcache="http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring/ehcache-spring-1.2.xsd"
       xmlns:context="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"
        >

    <mvc:annotation-driven/>
    <context:component-scan base-package="com.xxx"/>

    <bean id="templateErrorListener"
          class="com.stringtemplate.log.Slf4jStringTemplateErrorListener"/>

    <bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
          p:config-location="/WEB-INF/ehcache.xml"/>

    <ehcache:annotation-driven cache-manager="ehCacheManager"/>

</beans>

和我的dispatcher-servlet.xml看起来像：

我一直在进行一些重构，并将<mvc:annotation-driven/>从dispatcher-servlet.xml移到applicationContext.xml。

你不想这样做。 <mvc:annotation-driven/>用于启用注释样式的MVC控制器，这些控制器必须位于dispatcher-servlet.xml中。将<mvc:annotation-driven/>放在applicationContext.xml中是没有意义的，它没有任何有意义的效果。

我应该回答这个问题，但答案是，当你声明了mvc命名空间时，你没有告诉Spring在哪里找到它的模式。添加

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd

到schemaLocation

中的applicationContext.xml属性

移动<mvc：annotation-driven>后出错：找不到元素'mvc：annotation-driven'的声明</mvc：annotation-driven>
