org.xml.sax.SAXParseException ...找不到元素“上下文：组件扫描”的声明

Question

我有一个 Eclipse-Maven-Spring 项目和一个applicationcontext.xml。这是：

        <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:security="http://www.springframework.org/schema/security"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:context="http://www.springframework.org/schema/context"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
              http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
              http://www.springframework.org/schema/security/spring-security-3.1.xsd">

        <description>SoapClient1</description>

        <context:component-scan base-package="hu.bz.ikti.soap.test"/>
...
</beans>

解析xml时出现以下错误：

Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 19 in XML document from class path resource [META-INF/spring/app-context1.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'.
at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:396)

在后面的<http> xml 元素的开头有一个错误标志：

    cvc-complex-type.2.4.a: Invalid content was found starting with element 'http'. One of '{"http://
 www.springframework.org/schema/beans":import, "http://www.springframework.org/schema/beans":alias, 
 "http://www.springframework.org/schema/beans":bean, WC[##other:"http://www.springframework.org/
 schema/beans"], "http://www.springframework.org/schema/beans":beans}' is expected.

在xsi:schemaLocation 部分我尝试添加 http://www.springframework.org/schema/context/spring-context-3.2.xsd, spring-context-3.1.xsd, spring-context.xsd 但我总是遇到同样的错误。

我的pom.xml 中有以下内容：

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

有人可以帮帮我吗？

xsi:schemaLocation 不仅仅是一个架构列表，它是一个命名空间 URI 及其对应架构位置的对 列表。所以你需要更多类似的东西

 xsi:schemaLocation="
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
          http://www.springframework.org/schema/security
          http://www.springframework.org/schema/security/spring-security-3.1.xsd
          http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-3.1.xsd">
