对于打包成的jar包文件，需要读取jar里面的配置文件时，就会出现问题！对应修改如下：

package com.xiaomi.weather.utils;

import org.apache.log4j.Logger;

import java.io.*;
import java.util.Properties;

/**

 */
public class PropertiesUtil {
    public static Logger logger = Logger.getLogger(PropertiesUtil.class);
    public static Properties pros = new Properties();

    static {
        // 获取配置文件所在文件夹
        String configDir = PropertiesUtil.class.getClassLoader().getResource("").getPath();
        if (configDir.indexOf(".jar!") > -1) {//jar包
            try {
                InputStream ips = PropertiesUtil.class.getResourceAsStream("/service.properties");
                BufferedReader ipss = new BufferedReader(new InputStreamReader(ips));
                pros.load(ipss);
                System.out.println("============================XXX" + pros.get("mongoHost"));
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else {
            // 遍历文件夹下面的所有配置文件
            File dir = new File(configDir);
            File[] files = dir.listFiles();
            for (int i = 0; i < files.length; i++) {
                if (files[i].getName().indexOf(".properties") > -1) {
                    InputStream path = PropertiesUtil.class.getClassLoader().getResourceAsStream(files[i].getName());
                    try {
                        pros.load(path);
                    } catch (IOException e) {
                        logger.error("{}", e);
                    }
                }
            }
        }
    }
}

 获取jar内配置文件（scala）：

val regularInputStream = this.getClass.getClassLoader.getResourceAsStream("regular.txt")
val regularBr = new BufferedReader(new InputStreamReader(regularInputStream))
var line: String = null
while ( {
    line = regularBr.readLine();
    line != null
}) {
val i1 = line.indexOf("\t")
val i2 = line.indexOf("\t", i1 + 1)
val i3 = line.indexOf("\t", i2 + 1)
val i4 = line.indexOf("\t", i3 + 1)
val i5 = line.indexOf("\t", i4 + 1)
descriptions.append(new Regex(line.substring(i4 + 1, i5)))
appIds.append(line.substring(i1 + 1, i2))
titles.append(null)
}
