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。我按照这里的说明安装-a-cgi-on-tomcat。它适用于一个简单的 Web 应用程序。但是当我尝试使用 Spring MVC 实现它时，我在访问 cgi 文件时遇到了问题。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。附上web.xml的内容。

您映射CGIServlet到/cgi-bin/*和映射DispatcherServlet到/app/*- 请求<contextPath>/app/cgi-bin/proxy.cgi由 Spring 而不是 CGI 处理，这并不奇怪。

试试/pcms/cgi-bin/proxy.cgi吧。

答案是：您没有在 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 可能坐在它后面。Apache的配置详解在：http: //tomcat.apache.org/tomcat-6.0-doc/proxy-howto.html

请注意，OpenLayers 警告说它的 proxy.cgi 只是一个示例，可能没有足够好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 上提供 OpenLayers 客户端页面，并且它包含来自其他 GeoServer 或 Mapserver 的图层，则可以使用代理 servlet 并将其指定为：

OpenLayers.ProxyHost = "服务于该页面的服务器上的 sevlet URL";
