本文介绍了如何在项目中添加maven依赖以使用typesafe.config库，并展示了如何编写和组织配置文件如application.conf, common.conf, logindb.conf和mysql.conf。通过示例代码，演示了配置信息的读取过程，最终给出了执行结果。" 131474765,1430994,R语言实现时空探索性模型,"['R语言', '数据分析', '时空建模', '环境科学', '流行病学', '城市规划']

maven依赖：

 <dependency>
      <groupId>com.typesafe</groupId>
      <artifactId>config</artifactId>
      <version>1.3.3</version>
    </dependency>

测试代码如下：

import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;
import com.typesafe.config.ConfigValue;

import java.io.File;
import java.util.Map;

/**

public class ConfigTest {
    public static void main(String[] args) {


        /**
         *  使用步骤：
         *     1.在resource目录下创建配置文件(application.conf 或者 application.json 或者 application.properties)
         *       默认加载顺序conf->json->properties
         *       注意：只能conf,json,properties后缀格式文件
         *
         * 加载任意位置的配置文件——灵活
         *   Config c = ConfigFactory.parseFile(new File("*****.conf"))
         */
        File file = new File("E:\\logindb.conf");
        Config config1 = ConfigFactory.parseFile(file);

        /**
         * 加载指定的文件
         */
        Config config2 = ConfigFactory.load("mysql.conf");
        System.out.println(config2.getString("login.db.username"));
        System.out.println(config2.getString("login.db.password"));
        System.out.println("========================");
        /**
         * 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。
         */
        Config conf = ConfigFactory.load();

        //1、prdserver.conf 获取指定配置文件
        for (Config config : conf.getConfigList("Prdserver")) {
            System.out.println(config.getInt("id"));
            System.out.println(config.getString("ip")+":"+config.getInt("port")+" "+config.getInt("rpc"));
        }
        System.out.println("========================");

        //2、logindb.conf
        System.out.println(conf.getString("login.db.driver"));
        System.out.println(conf.getString("login.db.url"));
        System.out.println(conf.getString("login.db.username"));
        System.out.println("========================");

        //3、common.conf
        for (Map.Entry<String, ConfigValue> entry : conf.getConfig("res.android").entrySet()) {
            System.out.println(entry.getKey() + " " + entry.getValue().valueType() + " " + entry.getValue().unwrapped());
        }
        System.out.println("========================");

        // 3、common.conf
        for (Map.Entry<String, ConfigValue> entry : conf.getConfig("whitelist.member").entrySet()) {
            System.out.println(entry.getKey() + " " + entry.getValue().valueType() + " " + entry.getValue().unwrapped());
        }
        System.out.println("========================");

        //4、common.conf
        System.out.println(conf.getString("company_ip"));
        System.out.println(conf.getString("lobbyserver.ip"));
        System.out.println(conf.getString("lobbyserver.port"));
        System.out.println(conf.getString("lobbyserver.rpc"));

    }

application.conf：

globalIP=127.0.0.1

include "logindb"

include "common"

common.conf：

wan_res_url= "http://"${globalIP}":7963/Resource/AssetBundle/"

logindb.conf

# 账号服数据库
login.db.driver= com.mysql.jdbc.Driver
login.db.url= "jdbc:mysql://"${globalIP}":3306/test?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8"
login.db.username= root

mysql.conf

# 账号服数据库
login.db.driver= com.mysql.jdbc.Driver
login.db.url= "jdbc:mysql://localhost:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8"
login.db.username= root
login.db.password= test
login.db.activeConn= 100
