Akka config

config格式

complex-app {
  something = "hello world"

  # here we want a simple-lib-context unique to our app
  # which can be custom-configured. In code, we have to
  # pull out this subtree and pass it to simple-lib.
  simple-lib-context = {
    simple-lib {
      foo = "hello world complex1 foo"
      whatever = "hello world complex1 whatever"
    }
  }
}

解析方法

package com.usoft6;

import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;
import com.usoft3.SystemSettingDemo;

public class TypesafeConfigDemo {

    public static void main(String args[]) {
        // "config1" is just an example of using a file other than
        // application.conf
        // config1是在classpath路径下的配置文件名，该文件类型是conf文件类型
        Config config1 = ConfigFactory.load("complex1");

        // use the config ourselves
        System.out.println(config1.getString("complex-app.something"));
        System.out.println(config1.getString("complex-app.simple-lib-context.simple-lib.foo"));
        System.out.println(config1.getString("complex-app.simple-lib-context.simple-lib.whatever"));


        // ConfigFactory.parseString使用parseString直接解析
        Config config2 = ConfigFactory.parseString("akka.loggers = \"akka.testkit.TestEventListener\"");
        System.out.println(config2.getString("akka.loggers"));


        // 使用parseString 直接解析json字符串
        Config config3 = ConfigFactory.parseString("{\"a\":\"b\", \"c\":\"d\"}");
        System.out.println(config3.getString("a"));
        System.out.println(config3.getString("c"));
    }
}

typesafe下的config包可以用来读取配置文件，支持多种形式。

但是，若使用

ConfigFactory.load()

加载配置文件，只能加载src/main/resources目录下的application.conf文件，不够灵活。

通过研究发现，可以使用

val c = ConfigFactory.parseFile(new File("*****.conf"))

加载任意位置的配置文件
