讀取配置文件的代碼

package com.gosun.parse.constant;

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

import java.util.Map;

//加載配置文件中的內容
public class ConfigInfo {
    public static final Config config = ConfigFactory.load("merge-hbase.conf");
    //regex
    public static final String regex_accesslog_regexgw500 = config.getString("hbase.zookeeper.quorum");

    public static void main(String[] args) {
        for (Map.Entry<String, ConfigValue> entry : config.entrySet()) {
            System.out.println(entry.getKey());
        }
    }
}
