Spring Dispatcher Servlet Not Found Problem
提问by aykut
I'm trying to build a simple spring web application but I get the following error when I run it on Apache Tomcat 6.0
我正在尝试构建一个简单的 spring web 应用程序，但是当我在 Apache Tomcat 6.0 上运行它时出现以下错误
Class Not Found Exception org.springframework.web.servlet.DispatcherServlet
I'm using maven to handle libraries. At first I thought it was maven's fault but it adds spring and other libraries succesfully.
我正在使用 maven 来处理库。起初我认为这是 maven 的错，但它成功地添加了 spring 和其他库。

Make sure that your pom.xml is having compile time dependency like bellow
确保您的 pom.xml 具有如下所示的编译时依赖项
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>2.5.6</version>
<scope>compile</scope>
</dependency>
Once project is build unzip your war file see it has required dependencies packaged properly or not in WEB-INF/lib
构建项目后，解压缩您的War文件，看看它是否在 WEB-INF/lib 中正确打包了所需的依赖项

I added external jars thru java build path which were not reflected in web-inf/lib folder.so,the error occured.
我通过 java 构建路径添加了外部 jars，这些路径没有反映在 web-inf/lib 文件夹中。所以，发生了错误。
I copied all those jars and pasted in the web-inf/lib folder and then my prob got solved.
我复制了所有这些 jars 并粘贴到 web-inf/lib 文件夹中，然后我的问题得到了解决。
Hope it helps.

Check the deployment assembly from project properties.
If maven dependecies is missing add that.
Your deployment assembly should look like this
从项目属性检查部署程序集。如果缺少 maven 依赖项，请添加它。您的部署程序集应如下所示

Right click on project -> Properties -> Deployment Assembly -> Add ->Java Build path entries -> maven dependency -> Finesh.
右键单击项目-> 属性-> 部署程序集-> 添加-> Java 构建路径条目-> maven 依赖项-> Finesh。

If you can't find that class in WEB-INF/lib, the classloader won't either. Believe the JVM and assume that you (or Maven) has packaged or deployed it incorrectly.
如果您在 WEB-INF/lib 中找不到那个类，类加载器也不会。相信 JVM 并假设您（或 Maven）错误地打包或部署了它。

You may need to copy the contents of dist/ of the spring downloads and the required linked packages to web-inf/lib then try start server again
您可能需要将 spring 下载的 dist/ 内容和所需的链接包复制到 web-inf/lib，然后再次尝试启动服务器
