当我试图在浏览器上查看网页时，我收到此错误。匹配通配符是严格的，但在调度程序servlet中没有发现元素'context：component-scan'错误的声明

堆栈跟踪：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 10 in XML document from ServletContext resource [/WEB-INF/DefaultServlet-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 10; columnNumber: 71; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.

DefaultServlet-servlet.xml中：

<?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" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans.xsd 
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> 
    <mvc:annotation-driven /> 
    <context:component-scan base-package="com.projectShaun.controller" /> 
    <bean 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 
</beans>

我也将包括我的applicationContext，因为它也有代码在同一行：

<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"

    <property name="password" value="" /> 
    </bean> 
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource"></property> 
    <property name="annotatedClasses">

    <property name="hibernateProperties"> 
     <props> 
     <prop 
     key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>

    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" 
    p:sessionFactory-ref="sessionFactory"> 
    </bean> 
</beans>

我也相信我有正确的依赖ency在我的图书馆和POM：

<dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-context</artifactId> 
      <version>${spring.version}</version> 
     </dependency>

回答：

根据这一post“您还没有指定的上下文命名空间的架构位置，就是这个特定的错误的原因”。

但是，看起来你有它，所以让我们看看还有什么可以的。

一种选择可能是，你可以，因为你在你的applicationContext 使用 3.2指定弹簧豆的版本，所以可能是有益的使用DefaultServlet-servlet.xml中同一个。

我感到担心的另一件事是路径http://www.springframework.org/schema/p，据我所知这个你不需要指定的schemaLocation。这似乎是正确的，但我没有看到这么多的优势，加上一些XML命名空间没有被使用。所以，我修改了它并得到了这个，尝试一下，如果有帮助，希望它可以。从@
