Spring MVC的Java教程问题

Question

我下面这里提供的教程：

http://javahash.com/spring-4-mvc-hello-world-tutorial-full-example/ 

部署到tomcat后，运行良好的话，我得到这样的：

HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config 

type Exception report 

message Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config 

description The server encountered an internal error that prevented it from fulfilling this request. 

exception 

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config 
org.springframework.web.servlet.DispatcherServlet.triggerAfterCompletionWithError(DispatcherServlet.java:1284)

javax.servlet.http.HttpServlet.service(HttpServlet.java:725) 
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) 

root cause 

java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config 
org.springframework.web.servlet.support.JstlUtils.exposeLocalizationContext(JstlUtils.java:101) 
org.springframework.web.servlet.view.JstlView.exposeHelpers(JstlView.java:135)

javax.servlet.http.HttpServlet.service(HttpServlet.java:725) 
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) 

note The full stack trace of the root cause is available in the Apache Tomcat/8.0.12 logs. 

我有我所有的jar文件导入到我的eclipse项目中，所有东西似乎都很好，我似乎无法弄清楚这里发生了什么。

错误告诉你它找不到该类，因为它在您的应用程序中不可用。

如果使用Maven，请确保您有jstl神器的依赖：

<dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>jstl</artifactId> 
     <version>1.2</version> 
</dependency>
