I want to be able to deploy a .war file and detect which port the application is being served on. I have two grails' apps running within different tomcat instances, and ideally I would like to adapt the configuration of each app according to each specific tomcat instance. Each tomcat instance uses a different port, therefore detecting the port upon which the app is served means the app knows which tomcat instance the app is running in.

Thanks for any help!

我使用了一个外部化配置，以便两个 grails 应用程序都可以读取与每个相应的 tomcat 实例启动位置相关的配置。通过控制每个 tomcat 实例的启动位置，可以适当地配置每个 grails 应用程序。因此，通过将外部配置相对于启动tomcat目录放置特定grail的应用程序配置来实现！

第一个请求到达时获取端口是否足够？那么这可能会有所帮助：

    println request.requestURL
    println request.request.request.request.connector.port

如果没有，请查看这些页面 - 我想它们可能会有所帮助

无需请求即可从 tomcat 获取服务器端口号

永远记住，oyu 可以在您的 grails 应用程序中使用所有可用的 java 代码。
