配置grails.serverURL获取动态端口

Question

In my Config.groovy file, I have the grails.serverURL set for development, but the port is hard-coded to 8080.

A few developers, have different ports configured to prevent other running apps from conflicting (local-dev SOA for example).

What I've tried hasn't given me happy results.

1. I set the -Dserver-port=8090 in my run-app command
2. Referenced both ${server.port} and ${grails.server.port.http} in the grails.serverURL string

How can I reference the -Dserver-app value for use in the Config.groovy?

Answer 1

you can access your system properties using System.getProperty()

For example, run your grails app with:

grails -Dserver-app="foobar" run-app

Then in Config.groovy:

def ServerApp = System.getProperty("server-app"); //returns "foobar"
