Question

我需要根据运行的环境获取my.application.dev，my.application.qa或my.application：

我的应用程序属性如下：

application.prod=my.application
application.qa=my.application.qa
application.dev=my.application.dev
application.property=${application.${env.name}}

这是我的代码：

InputStream input = this.getClass().getClassLoader().getResourceAsStream("application.properties");
// Let's say that I have a environment var to determinate if it's running in dev, qa or prod
// At this point, I do something like this String env = System.getenv("envName");

**我在这里可以做的是将$ {env.name}}设置为env **

Properties props = new Properties();
props.load(input);
String myValue = props.getProperty("application.property");

有什么主意吗？谢谢

在application.properties中定义：

application.prod=my.application
application.qa=my.application.qa
application.dev=my.application.dev

然后读取所需的属性：

String env = System.getProperty("envName");
try (InputStream input = getClass().getClassLoader().getResourceAsStream("application.properties")) {
  Properties props = new Properties();
  props.load(input);
  String value = props.getProperty("application." + env);
  System.out.println(value);
} catch (IOException ex) {
  ex.printStackTrace();
}

在运行时设置application.properties
