是可以的：（tomcat做server時(shí)，要加上項(xiàng)目名稱）：
http://localhost:8080/spring-mvc-study/hello/mvc? 運(yùn)行后報(bào)503錯(cuò)誤，發(fā)現(xiàn)沒有導(dǎo)入jstl的jar包，導(dǎo)入pom的坐標(biāo)：
<dependency>?
<groupId>javax.servlet</groupId>?
<artifactId>jstl</artifactId>?
<version>1.2</version>?
</dependency>
完成：

大哥，你的問題解決了嗎，我跟你一樣的問題，我用的tomcat運(yùn)行的，訪問http://localhost:8080/ZLearnSpringMvc/hello/mvc就報(bào)錯(cuò)，ZLearnSpringMvc是我的項(xiàng)目名,求解答啊。。

這個(gè)問題我已經(jīng)完全解決了，之間還遇到許多問題。
聽我說可能的原因，首先這個(gè) jetty的啟動沒什么問題，它已經(jīng)啟動了，然后由于是jetty做的web容器，所以你訪問的應(yīng)該是 ?http://localhost:8080/hello/mvc?, 但是出現(xiàn)報(bào)錯(cuò)，看不出原因，因此我建議把jetty停掉，改為tomcat啟動（用tomcat可以快速定位原因），此時(shí)先看它控制臺有沒有異常輸出，然后tomcat 訪問地址應(yīng)該是：?http://localhost:8080/你的項(xiàng)目名/hello/mvc? ，再看 異常輸出，之后就是對這些異常依個(gè)排除就行了。
等到tomcat可以正常訪問，那換成jetty也可以訪問了。
ps:順便說一下我遇到的問題，
第一個(gè)問題是 ?java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet 。。。
? ?解決方法：**工程名上右擊 -> Properties -> Deployment Assembly，
Add -> Java Build Path Entries -> next -> 選擇maven Dependencies**
第二個(gè)問題是 jstl not found?
解決方法：在pom.xml里 加入：
<dependency>?
<groupId>javax.servlet</groupId>?
<artifactId>jstl</artifactId>?
<version>1.2</version>?
</dependency>

http://localhost:8080/spring-mvc-study/hello/mvc這個(gè)也不行

我不知道老師是怎么運(yùn)行出來的，我用的myeclipse中的tomcat，應(yīng)該輸入http://localhost:8080/項(xiàng)目名/hello/mvc,才能正常顯示
2016-09-05
你的項(xiàng)目名叫weishop吧，你訪問
http://localhost:8080/weishop/mvc才可以吧
