java 读取.properties参数

Posted 2020-12-23 敲代码的机车Boy

注意需要引入spring的架包，spring-core-xxxxx


1.PropertiesUtil.java

package com.h3c.portal.business.common.util;

import org.springframework.core.io.support.PropertiesLoaderUtils;

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

/**
 * 读取Properties配置文件内的参数
 */
public class PropertiesUtil {

    public static void main(String[] args) {
        Properties prop = getProperties_1();
        // 根据关键字查询相应的值
        String value = prop.getProperty("OA_DBNAME");
        System.out.println("wechat_appid = " + value);
        System.out.println("*********************************************");
    }

    public static Properties getProperties_1() {
        Properties prop = null;
        try {
            // 通过Spring中的PropertiesLoaderUtils工具类进行获取
            prop = PropertiesLoaderUtils.loadAllProperties("conf/url.properties");
        } catch (IOException e) {
            e.printStackTrace();
        }
        return prop;
    }
}

2.url.properties

OA_DBNAME=test
OA_SERVERIP=10.1.1.11
OA_DB_USERNAME=oa_aas
OA_DB_USERPWD=oa_dad_12313
