我有一个在jetty servlet中运行的webapp。
启动时,它在localhost:8888 /
上运行我正在使用单独的Ruby / Sinatra流程来管理我的资产(js,css,images)。 这在localhost:3000 /
上运行理想情况下,我希望Jetty ProxyServlet将来自localhost:8888 / assets / *的任何请求发送到localhost:3000 / assets / *,以避免跨域错误。
这只是在开发中,我的生产资产将在其他地方提供,因此不要在可扩展性或其他问题的背景下回答。
另外,我需要这两个“Servlets”在同一个PORT 8888中运行sidebyside? p>
再次...... 对localhost的所有请求:8888 / *(/ assets / 除外)将路由到主webapp servlet。 对localhost的所有请求:8888 / assets / 将路由到ruby / sinatra服务器localhost:3000 / assets / *

我在想这样的事情?
但它只会导致503 Service Unavailable

<servlet-class>org.mortbay.servlet.ProxyServlet$Transparent</servlet-class>
<init-param>
<!-- This points to the actual server where requests are proxied to -->
<param-name>ProxyTo</param-name>
<param-value>http://localhost:3000/</param-value>
</init-param>
<init-param>
<!-- This will be stripped off the client request URL -->
<param-name>Prefix</param-name>
<param-value>/</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JettyProxy</servlet-name>
<url-pattern>/assets/*</url-pattern>
</servlet-mapping>
这可能吗?如果是这样,它将如何实施?
答案 0 :(得分:3)
您的标记表明您使用的是 jetty-8 ,但您的代理servlet类指示 jetty-6 (org.mortbay.servlet.ProxyServlet
)。在jetty-8上你应该使用的ProxyServlet是org.eclipse.jetty.servlets.ProxyServlet
,是的,这听起来像是一个非常正常的用例。
