运行spring mvc-hibernate应用程序时出现异常

Question

我收到以下异常

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in XML document from ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 107; cvc-elt.1.a: Cannot find the declaration of element 'beans:beans'

我的servlet-context.xml如下，

我已经拿了spring mvc和hibernate应用的集成代码。我根据我的要求修改了一些代码。运行代码时出现上述异常。有什么解决办法吗。我拿的代码运行良好。但无法运行修改后的代码。

我想问题可能出在以https 与http 开头的命名空间。尝试在根元素中使用以下命名空间声明：

<beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns="http://www.springframework.org/schema/mvc"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
    https://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    https://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    https://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/tx 
    https://www.springframework.org/schema/tx/spring-tx.xsd">
