【问题描述】：

我尝试了很多可能性，但没有一个对我有用。一世有一个使用 maven 和 eclipse 作为构建工具的 spring mvc 应用程序。在我的应用程序配置了上下文加载侦听器和调度程序调度程序 servlet 中的 servlet 我配置我的 spring 配置文件，但它显示文件未找到异常 WEB-INF/applicationContext.xml。但我没有 applicationContext.xml 文件在我的应用程序中。我需要两者 ContextLoadListener 和dispatcher servlet。如何解决这个问题。这是我的 Web.xml 文件

    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>indexNew.jsp</welcome-file>
    </welcome-file-list>
</web-app>

我在运行 url 时遇到的错误是 http://localhost:8080/sdnext/ 我得到的输出是错误页面 404 说“请求资源不可用（/sdnext/）

在控制台中我收到错误

标签： eclipse spring maven spring-mvc tomcat

【解决方案1】：

--- 已编辑 --- 经过长时间的聊天讨论，在 maven 项目的设置中发现了问题。它没有遵循标准的 Maven 项目目录结构。 xml 文件没有被复制到预期的目标位置，并且无法被上下文加载器加载。

【讨论】：

感谢重播，但是当我按照您的建议更改代码时，它现在显示此错误：原因：java.io.FileNotFoundException：无法打开 ServletContext 资源 [/WEB-INF/servlet- context.xml]
你的 servlet-context.xml 在哪里？在您的原始帖子中，路径是：/WEB-INF/config/servlet-context.xml not /WEB-INF/servlet-context.xml
我的应用程序结构是：MyApplication-->WebRoot-->WEB-INF-->Config--->Servlet-Context.xml 这是我的项目结构
在您的 context-param 条目中，您是否输入了路径：/WEB-INF/config/servlet-context.xml 或 /WEB-INF/servlet-context.xml
我第一次尝试使用这两种方式，将 /WEB-INF/config/serlvet-context.xml 放在这之后，这次我将 servlet-context.xml 文件直接保存在 WEB-INF 中它显示“java.io.FileNotFoundException：无法打开 ServletContext 资源 [/WEB-INF/sdnext-servlet.xml]”
