Question

当我尝试在浏览器上查看网页时，我收到此错误。

stacktrace ：

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>

此外，我将包含我的applicationContext，因为它也有相同的代码行：

<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"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/beans

  <tx:annotation-driven/>

  <context:component-scan base-package="com.projectShaun.controller" />

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/projectshaun" />
    <property name="username" value="root" />
    <property name="password" value="" />
  </bean>

  <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
     <property name="annotatedClasses">
            <list>
                <value>com.projectShaun.model.Account</value>
            </list>
        </property>
    <property name="hibernateProperties">
      <props>
        <prop 
         key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        <prop key="hibernate.show_sql">true</prop>
      </props>
    </property>
  </bean>

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

我也相信我的库和pom中有正确的依赖：

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

根据此post＆＃34; 您尚未指定上下文命名空间的架构位置，这就是此特定错误的原因＆＃34;。

然而，似乎你拥有它，所以让我们看看它还有什么。

一个选项是您可以指定 spring-beans 的版本，因为您在 applicationContext 中使用了3.2，因此在使用相同的版本中可能会有所帮助 DefaultServlet-servlet.xml中

我感到担心的另一件事是路径 http://www.springframework.org/schema/p ，据我所知，你不需要指定的schemaLocation 。它似乎是正确的，但是我没有看到这里有很多优点，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它，尝试它是否有帮助，希望它能。

匹配的通配符是严格的，但是没有找到元素＆＃39; context的声明：component-scan＆＃39;调度程序servlet中的错误
