如何通过码头通配符以编程方式设置处理程序的上下文路径？

Question

Usually in jetty you specify the context path in xml

<bean id="myHandler" class="org.eclipse.jetty.server.handler.MyHandler">
    <property name="handler" ref="myHandler" />
    <property name="contextPath" value="/myHandler" />
</bean>

Is there a way to set a handler with wild path contextpath programmatically without xml?

Answer 1

contextPath is the parent path for all content under that context.

Jetty will only submit your request to that Handler if the contextPath matches. This is essentially a read-only value that can only be set before startup of that Handler's LifeCycle.

So if you used say /api then that's essentially the same as /api/* and /api/

You can then use the standard HttpServletRequest details to get access to what URI was actually submitted to you.

You might want to just use ServletContextHandler and normal Servlets if you have a need to slice/dice the URI in more complex ways.

You can even take advantage of the PathMappings found in the ServletContextHandler to map your Servlet's in creative ways (prefix, exact, suffix, glob, regex, uri-template, etc).
