java读取properties文件的两种方式

配置文件在src目录下

直接上代码了

package com.po.test;

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

public class Test {
    public static void main(String[] args) {
        Properties prop = new Properties();
        try {             
            prop.load(ClassLoader.getSystemResourceAsStream("test.properties"));
            String url = (String) prop.get("url");
            System.out.println("Properties方法获取："+url);
        } catch (IOException e) {
            e.printStackTrace();
        }
        ResourceBundle bundle = ResourceBundle.getBundle("test");
        String url = bundle.getString("url"); 
        System.out.println("ResourceBundle方法获取："+url);
    }
}
