虽然关于这个主题有很多问题，但我找不到任何匹配的答案，而且我是 Spring 和 REST 的新手。这是我的配置文件：

web.xml：

<web-app>
    <display-name>Archetype Created Web Application</display-name>
    <!--
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener> -->

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>src/main/WEB-INF/dispatcher-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

启动我的 Tomcat 版本 9 网络服务器时，总是向我显示以下错误消息：

有人有什么想法吗？我的知识已经到了尽头......

这是我的项目的概述：Order of my Project

【问题讨论】：

如果你解压你的WAR（或者只是浏览服务器上的app目录），你的dispatcher-config.xml在正确的位置吗？
更正您的“dispatcher-config.xml”位置。
首先感谢答案。在 IntelliJ 中，您可以右键单击文件并将相对路径复制到该文件。这就是我所做的，但它并没有解决问题。

标签： java xml spring rest intellij-idea

【解决方案1】：

xml 文件名应该是 dispatcher-servlet.xml

    <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/spring/*</url-pattern>
</servlet-mapping>

【讨论】：

对不起，我也试过这个，但我得到了同样的错误：/

【解决方案2】：

您可以尝试将 dispatcher-config.xml 移动到 'resources' 文件夹并将 'src/main/WEB-INF/dispatcher-config.xml' 更改为 'classpath:dispatcher-config.xml'
