JAVA 获取本机信息 收集整理

时间：2022-01-25 10:59:19

1）最简单的获取本机的机器名

import java.net.InetAddress;
import java.net.UnknownHostException;

public class GetInfo {	
	
	public static void main(String[] args) throws UnknownHostException {
		 InetAddress s = InetAddress.getLocalHost();
		 System.out.println(s.getHostName());
	}

}
输入结果：

PC-201012262159



2）获取Java环境信息和操作系统环境信息

import java.util.*;

public class GetInfo {	
	
	public static void main(String[] args) {
		Properties props = System.getProperties();
		System.out.println("Java的运行环境版本：" + props.getProperty("java.version"));
		System.out.println("Java的运行环境供应商：" + props.getProperty("java.vendor"));
		System.out.println("Java供应商的URL："+ props.getProperty("java.vendor.url"));
		System.out.println("Java的安装路径：" + props.getProperty("java.home"));
		System.out.println("Java的虚拟机规范版本："+ props.getProperty("java.vm.specification.version"));
		System.out.println("Java的虚拟机规范供应商："	+ props.getProperty("java.vm.specification.vendor"));
		System.out.println("Java的虚拟机规范名称："+ props.getProperty("java.vm.specification.name"));
		System.out.println("Java的虚拟机实现版本："+ props.getProperty("java.vm.version"));
		System.out.println("Java的虚拟机实现供应商："	+ props.getProperty("java.vm.vendor"));
		System.out.println("Java的虚拟机实现名称：" + props.getProperty("java.vm.name"));
		System.out.println("Java运行时环境规范版本："	+ props.getProperty("java.specification.version"));
		System.out.println("Java运行时环境规范供应商："+ props.getProperty("java.specification.vender"));
		System.out.println("Java运行时环境规范名称："	+ props.getProperty("java.specification.name"));
		System.out.println("Java的类格式版本号："+ props.getProperty("java.class.version"));
		System.out.println("Java的类路径：" + props.getProperty("java.class.path"));
		System.out.println("加载库时搜索的路径列表："	+ props.getProperty("java.library.path"));
		System.out.println("默认的临时文件路径：" + props.getProperty("java.io.tmpdir"));
		System.out.println("一个或多个扩展目录的路径：" + props.getProperty("java.ext.dirs"));
		System.out.println("操作系统的名称：" + props.getProperty("os.name"));
		System.out.println("操作系统的构架：" + props.getProperty("os.arch"));
		System.out.println("操作系统的版本：" + props.getProperty("os.version"));
		System.out.println("文件分隔符：" + props.getProperty("file.separator"));  //在 unix 系统中是＂／＂
		System.out.println("路径分隔符：" + props.getProperty("path.separator")); // 在 unix 系统中是＂:＂
		System.out.println("行分隔符：" + props.getProperty("line.separator")); // 在 unix系统中是＂/n＂
		System.out.println("用户的账户名称：" + props.getProperty("user.name"));
		System.out.println("用户的主目录：" + props.getProperty("user.home"));
		System.out.println("用户的当前工作目录：" + props.getProperty("user.dir"));
	}

}

3）获取本机MAC地址和实时IP地址 

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Formatter;
import java.util.Locale;

public class GetInfo {	
	
	public static void main(String[] args) throws UnknownHostException, SocketException {
		InetAddress address = InetAddress.getLocalHost();
        NetworkInterface ni = NetworkInterface.getByInetAddress(address);
        ni.getInetAddresses().nextElement().getAddress();
        byte[] mac = ni.getHardwareAddress();
        String sIP = address.getHostAddress();
        String sMAC = "";
        Formatter formatter = new Formatter();
        for (int i = 0; i < mac.length; i++) {
            sMAC = formatter.format(Locale.getDefault(), "%02X%s", mac[i],
                    (i < mac.length - 1) ? "-" : "").toString();
        }
        System.out.println("IP：" + sIP);
        System.out.println("MAC：" + sMAC);
	}

}

输出结果：

IP：10.192.33.64
MAC：00-21-86-58-39-C6



4）获取本机用户名、计算机名、计算机域名

import java.util.Map;

public class GetInfo {	
	
	public static void main(String[] args) {
		Map<String, String> map = System.getenv();
		  String userName = map.get("USERNAME");// 获取用户名
		  String computerName = map.get("COMPUTERNAME");// 获取计算机名
		  String userDomain = map.get("USERDOMAIN");// 获取计算机域名
		  System.out.println(userName);
		  System.out.println(computerName);
		  System.out.println(userDomain);
	}

}
使用自带的 System.getenv()方法获得一个Map

输出结果：

Administrator
PC-201012262159
PC-201012262159



5）获取本机的实时IP、计算机名、操作系统名、操作系统版本

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.Properties;

public class GetInfo {	
	
	public static void main(String[] args) throws UnknownHostException {
		InetAddress addr = InetAddress.getLocalHost();  
        String ip=addr.getHostAddress().toString(); //获取本机ip
        String hostName=addr.getHostName().toString(); //获取本机计算机名称
        System.out.println("本机IP："+ip+"\n本机名称:"+hostName);
        Properties props1=System.getProperties(); 
        System.out.println("操作系统的名称："+props1.getProperty("os.name")); 
        System.out.println("操作系统的版本："+props1.getProperty("os.version"));  
	}

}
输出结果：

本机IP：10.192.33.64
本机名称:PC-201012262159
操作系统的名称：Windows XP
操作系统的版本：5.1
