如何从 play 框架中的 application.conf 文件中读取属性？

Question

I am a bit new to play framework. I am trying to get a property from the application.conf file to a controller class. Is there any way to do it?

Let's say we have defined a path as below in the application.conf

ProxyPass /testPath / http://127.0.0.1:8080/

So I need to get it to a controller class. how can I do that?

Answer 1

Suppose you have added cache.aerospike.namespace=1234 in your application.conf , you can access it in your controller like this:

public class MyController extends Controller {

   String nameSpace = Play.application().configuration().getString("cache.aerospike.namespace");
}

Answer 2

Just inject an instance of Config to the controller:

import com.typesafe.config.Config;
import play.mvc.Controller;

import javax.inject.Inject;

public class MyController extends Controller {

    private final Config config;

    @Inject
    public MyController(Config config) {
        this.config = config;
    }
}
