我在使用 Spring 的 Web 应用程序中创建纯 Camel 上下文时遇到问题。在重新创建问题之前，我创建了一个新的 maven 项目并删除了我的 maven 存储库。项目中除了 Maven 添加的文件外，仅有 InitialContext.xml、web.xml 和 pom.xml。初始上下文文件如下所示：

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <display-name>CamelSpring</display-name>

    <context-param>
        <param-name>
            contextConfigLocation
        </param-name>
        <param-value>
            /WEB-INF/InitialContext.xml
        </param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

</web-app>

初始上下文.xml

<?xml version="1.0" encoding="US-ASCII"?>

<beans 
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我收到一个错误，如下所示：

我一直在环顾四周，但找不到任何表明此设置有什么问题的东西。我希望它只是我没有添加到 pom 中的东西。有没有人对如何解决这个问题有任何想法？

这通常是由于使用了不同版本的 spring 模块而发生的。对所有 spring 依赖项（包括 xsd 中的依赖项）使用相同的版本应该会有所帮助。

更改 pom.xml 中的版本后，错误得到解决。
