Question

您好我是Spring的新手，我正在尝试构建一个简单的spring MVC项目但是当我运行我的代码时，我得到了：Web应用程序中的Servlet [mvc-dispatcher]抛出了load（）异常java.lang.ClassNotFoundException

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"
    version="2.5">

    <display-name>Sample Spring Maven Project</display-name>

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

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

</web-app>

spring-config.xml是

我最近遇到了同样的错误。我在Eclipse（Luna）中运行了一个Spring MVC项目。我关闭了“自动构建”选项，这就产生了问题。尝试重新打开并尝试再次运行该项目。
