一、在src下創建

二、propertites文件內容

三、代碼

package com.css.java.learning.massbag;

import java.io.FileInputStream;
import java.util.Properties;
/**
 * java讀取propertites配置文件
 * @author Red_Ant 20180926
 */
public class ReadProperty {
    public static void redPropertites() {
        FileInputStream in = null;
        try {
            Properties properties = new Properties();
            in = new FileInputStream(ReadProperty.class.getResource("20180926.properties").getPath());
            properties.load(in);
            StringBuilder sb = new StringBuilder();
            sb.append(properties.getProperty("r"));
            sb.append(properties.getProperty("e"));
            sb.append(properties.getProperty("d"));
            sb.append(properties.getProperty("a"));
            sb.append(properties.getProperty("n"));
            sb.append(properties.getProperty("t"));
            System.out.println("讀取配置信息成功！");
            System.err.println(sb);
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("讀取配置信息失敗！");
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }

    public static void main(String[] args) {
        redPropertites();
    }
}
