我尝试了网上给出的几种解决方案，比如 1) 授予对所有文件的读、写权限 - 不起作用 2) 添加 init-param - 不起作用 3) 将 dispatcherservlet 的路径显式指定为/WebContent/WEB-INF/dispatcher-servlet.xml - 不起作用。

我在 Apache tomcat 服务器 v7.0 上运行项目时出现此错误

过去 4 天我一直被这个问题困扰。请帮我。

以下是有效的解决方案。

您的 war 没有 dispatcher-servlet.xml。 1) 该项目没有 webapp 文件夹。使用 maven 创建项目时请注意。您可以按照此处提到的步骤操作 http://blog.manishchhabra.com/2013/04/spring-data-mongodb-example-with-spring-mvc-3-2/ 您可能会使用一些奇怪的 maven 原型(prototype)创建项目。尝试上面的链接，它有效。

我在互联网上的其他地方找不到这个解决方案。 :)

Answer 1

Spring 为 Web 应用程序创建了两个应用程序上下文。第一个是包含应用程序 bean 的根应用程序上下文，例如 DAO 服务对象等。此上下文(在您的情况下为 applicationContext.xml)是使用上下文参数 contextConfigLocation 配置的。第二个是包含您的 Web 特定 bean 的子 Web 应用程序上下文。这是使用调度程序 servlet 的 init-param contextConfiguration 配置的。

在您的情况下，您已经为两者复制了配置文件。如下更改您的 web.xml

<web-app 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"
