Java读取properties配置文件

一.创建properties配置文件

file_upload_path=http://localhost:8011/ecps-file
solr_path=http://localhost:8080/solr
deploy_html_path=C:/Users/user/workspac/gxshop1/ecps-parent0317/ecps-portal/src/main/webapp/html
ws_pass=123
portal_path=http://localhost:8021/ecps-portal
request_file_path=http://localhost:8011/ecps-file
host_path=192.168.43.192
port_path=6379
key_val=key_val

二.创建util工具类

package util;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class ECPSUtils {
    
    public static String getProp(String key){
        //定义一个临时的值变量
        String value = "";
        //创建properties对象
        Properties p = new Properties();
        //类加载器(读取配置文件)
        InputStream is = ECPSUtils.class.getClassLoader().getResourceAsStream("ecps_prop.properties");
        try {
            //从输入流中读取属性列表(键值对)
            p.load(is);
            //通过形式参数的key获取值
            value = p.getProperty(key);
            //关闭流
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return value;
    }
    
}

三.创建测试类

package test;

import util.ECPSUtils;

public class TestProperties {
    public static void main(String[] args) {
        String file_upload_path = ECPSUtils.getProp("file_upload_path");
        System.out.println(file_upload_path);
    }
}

四.结果
