java - cvc-complex-type.2.4.c : The matching wildcard is strict, 但找不到元素 'mvc:annotation-driven' 的声明

Question

我想这是一个 xml 解析问题，但我就是看不到它在哪里。我阅读了一些有关该主题的文章，但没有任何帮助:

我有这个 spring mvc 配置:

<?xml version='1.0' encoding='UTF-8' ?>
<!-- was: <?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc" 
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
       http://www.springframework.org/schema/tx

       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context-4.0.xsd"
       >

    <mvc:annotation-driven />
    <context:component-scan base-package="controllers" />


    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" /> 

</beans>

这是 tomcat 所说的:

知道我的代码中可能有什么问题吗？

谢谢

如果查看架构位置，您会注意到包含 http://www.springframework.org/schema/security 的行。

这一行打破了预期的格式，格式应该是[namespace] [xsd-location]。这一行基本上搞乱了正确的格式。要解决此问题，请添加 xsd 位置或删除该行。为了防止这种情况，我通常也在 xsi:schemaLocation 属性的布局中遵循格式(如果您相应地设置格式，很明显该部分丢失了)。

 xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 
    http://www.springframework.org/schema/security
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

作为额外的提示，建议使用无版本的 xsd 文件，而不是 spring-beans-4.0.xsd 使用 spring-beans.xsd。

 xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd 
    http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
