Question

我正在尝试在基于spring框架的WEB应用程序中使用Openlayer。我需要在tomcat上使用cgi代理。我按照installing-a-cgi-on-tomcat的说明进行操作。它适用于简单的Web应用程序。但是当我尝试使用Spring MVC实现它时，我遇到了访问cgi文件的问题。我收到了警告信息。

 WARN org.springframework.web.servlet.PageNotFound:962 - No mapping found for HTTP request with URI [/pcms/app/cgi-bin/proxy.cgi] in DispatcherServlet with name 'Spring MVC Dispatcher Servlet'

我尝试了很多方法，但我没有弄清楚如何访问WEB-INF \ cgi目录下的proxy.cgi文件。请帮忙。谢谢。附件是web.xml的内容。

Answer 1

您已将CGIServlet映射到/cgi-bin/*并将DispatcherServlet映射到/app/* - 毫不奇怪，<contextPath>/app/cgi-bin/proxy.cgi的请求由Spring而不是CGI处理。

请尝试/pcms/cgi-bin/proxy.cgi。

Answer 2

答案是：您不在Tomcat上安装或使用cgi代理。

cgi适用于用作前端服务器的apache服务器或IIS。 Tomcat可能会坐在它后面。 Apache的配置详见：http://tomcat.apache.org/tomcat-6.0-doc/proxy-howto.html

警告OpenLayers警告它的proxy.cgi只是一个例子，可能没有足够的检查来阻止它被利用，即它可能运行一些恶意脚本。

如果您仅在Tomcat上为OpenLayers客户端页面提供服务，并且它包含来自其他GeoServer或Mapserver的层，您可以使用代理Servlet并将其指定为：

OpenLayers.ProxyHost =“服务此页面的服务器上的sevlet URL”;
