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
