    是可以的：（tomcat做server时，要加上项目名称）：

    http://localhost:8080/spring-mvc-study/hello/mvc  运行后报503错误，发现没有导入jstl的jar包，导入pom的坐标：

    <dependency> 

    <groupId>javax.servlet</groupId> 

    <artifactId>jstl</artifactId> 

    <version>1.2</version> 

    </dependency>

    完成：

    大哥，你的问题解决了吗，我跟你一样的问题，我用的tomcat运行的，访问http://localhost:8080/ZLearnSpringMvc/hello/mvc就报错，ZLearnSpringMvc是我的项目名,求解答啊。。

    这个问题我已经完全解决了，之间还遇到许多问题。

    听我说可能的原因，首先这个 jetty的启动没什么问题，它已经启动了，然后由于是jetty做的web容器，所以你访问的应该是  http://localhost:8080/hello/mvc , 但是出现报错，看不出原因，因此我建议把jetty停掉，改为tomcat启动（用tomcat可以快速定位原因），此时先看它控制台有没有异常输出，然后tomcat 访问地址应该是： http://localhost:8080/你的项目名/hello/mvc  ，再看 异常输出，之后就是对这些异常依个排除就行了。

    等到tomcat可以正常访问，那换成jetty也可以访问了。


    ps:顺便说一下我遇到的问题，

    第一个问题是  java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet 。。。

       解决方法：**工程名上右击 -> Properties -> Deployment Assembly，
    Add -> Java Build Path Entries -> next -> 选择maven Dependencies**


    第二个问题是 jstl not found 

    解决方法：在pom.xml里 加入：

    <dependency> 

    <groupId>javax.servlet</groupId> 

    <artifactId>jstl</artifactId> 

    <version>1.2</version> 

    </dependency>

    我不知道老师是怎么运行出来的，我用的myeclipse中的tomcat，应该输入http://localhost:8080/项目名/hello/mvc,才能正常显示

    你的项目名叫weishop吧，你访问

    http://localhost:8080/weishop/mvc才可以吧
