使用env变量配置Jetty应用程序 [英] Configuring a Jetty application with env variables

问题描述

我试图使用Docker在Jetty 9中部署Java WAR文件。我想配置东西作为数据库URI字符串，loglevel等通过环境变量 - 所以我也可以使用Docker的链接功能。

I'm trying to deploy a Java WAR file in Jetty 9 with Docker. I would like to configure things as database URI string, loglevel and such via environment variables - so that I could also use the link features of Docker.

但是，如果我开始应用程序通过 java -jar start.jar ，我设置的环境变量不可用于应用程序。

But, if I start the application via java -jar start.jar, the environment variables I've set are not available to the application.

推荐答案

使用系统环境变量（aka 系统。 Jetty的 start.jar

Using system environment variables (aka System.getenv(String)) is not supported by Jetty's start.jar

但是请注意，Jetty start.jar process支持属性，作为系统属性或作为开始属性。可以在命令行上或在 $ {jetty.base} /start.ini

Know however, that the Jetty start.jar process does support properties, either as System properties, or as start properties. Either on the command line or in the ${jetty.base}/start.ini
