java使用properties文件

package com.property;

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

public class MainProperty {
    public static void main(String[] args) throws IOException {
        Properties properties=new Properties();
        //路径
        String url=System.getProperty("user.dir");
        System.out.println(url);
        File dire=new File("");
        String URI=dire.getCanonicalPath();
        System.out.println(URI);
        //包名
        String packString=(new MainProperty()).getClass().getPackage().getName();
        System.out.println(packString);
        FileInputStream fis=new FileInputStream(url+"\\src\\main\\java\\com\\property\\my.properties");
        properties.load(fis);
        fis.close();
        System.out.println("sitename:"+properties.getProperty("sitename"));
        System.out.println("siteURL:"+properties.getProperty("siteURL"));
    }
}
