【问题描述】：
我有一个适用于 Tomcat 8 和 Jetty 8 的 webapp。最近，我们引入了 servlet-mappings
<servlet>
<servlet-name>page</servlet-name>
<jsp-file>/Dashboard.html</jsp-file>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>page</servlet-name>
<url-pattern>/editjob</url-pattern>
</servlet-mapping>
当你输入一个带有“http://localhost:8080/app/editjob”的url时，在tomcat中被重定向到“http://localhost:8080/app/Dashboard.html”。但是当我们使用 embed Jetty 部署它时，会返回 404 Not Found 它。似乎 servlet 映射不起作用。
HTTP ERROR 404
Problem accessing /app/page. Reason:
Not Found
Powered by Jetty://
我可以直接使用进入应用程序 http://localhost:8080/app/Dashboard.html。没有映射，我们对码头没有问题 这是嵌入Jetty的代码：
final Server server = new Server();
SocketConnector connector = new SocketConnector();
connector.setMaxIdleTime(-1);
connector.setSoLingerTime(-1);
connector.setPort(8080);
server.setConnectors(new Connector[]{connector});
final WebAppContext context = new WebAppContext();
context.setServer(server);
context.setContextPath("app");
context.setWar(location.toExternalForm());
server.setHandler(context);
context.start();
server.join();
这是带有映射的 web.xml。

我尝试在启动服务器时定义 servlet 映射，但没有成功。 此映射与 Tomcat 完美配合，但 Jetty...我不知道可能是哪个问题。
提前致谢。
