通过java的Runtime.getRuntime()和System.getProperties()来获取系统的信息

第一种，通过Runtime.getRuntime()来获取系统信息。

通过java来获取系统以下的信息：

主机名:          

OS 名称:         
OS 版本:         

OS 制造商:      

OS 配置:         

独立工作站
OS 构件类型:     

注册的所有人:    

注册的组织:      

产品 ID:       
初始安装日期:    

系统启动时间:    

系统制造商:      
系统型号:        

系统类型:        

处理器:           
BIOS 版本:       

Windows 目录:    

系统目录:       

启动设备:     

系统区域设置:    

输入法区域设置:  
时区:            

物理内存总量:   

可用的物理内存:  虚拟内存:

最大值: 虚拟内存:

可用:  虚拟内存:

使用中: 4,442 MB
页面文件位置:  

 域:          

 登录服务器:  

修补程序:                        
网卡:      

import java.io.IOException;
public class testCase {

    public static void main(String[] args) {
        
        /**
         * cmd空格/k空格systeminfo:执行字符串指定的命令但保留
         * 
         * systeminfo:查看系统信息
         */
        try {
            Runtime.getRuntime().exec("cmd /k systeminfo > d:/xx.txt");
            System.out.println("执行完毕！");
        } catch (IOException e) {
            System.out.println("生成文件失败！");
            e.printStackTrace();
        }
    }
}

到D盘查看一下xx.txt文件。

可以看见：

 第二种，通过Properties props=System.getProperties();来获取系统信息。

package com.souvc.test;

import java.util.Enumeration;
import java.util.Iterator;
import java.util.Properties;
import java.util.Map.Entry;

public class SystemInfo {

    public static void main(String[] args) {

       Properties props=System.getProperties(); 
       
       // show keys  
       //showKeys(props);  
 
       // show values  
       //showValues(props);  
 
       // show keys and values  
       showKeysAndValues(props);
       
       //show SystemInfo
       showSystemInfo(props);
       
    }

    /**
     * 
     *显示Keys-values值
     */
    private static void showKeysAndValues(Properties props) {
        Iterator<Entry<Object, Object>> it = props.entrySet().iterator();  
        while (it.hasNext()) {  
            Entry<Object, Object> entry = it.next();  
            Object key = entry.getKey();  
            Object value = entry.getValue();  
            System.out.println("key   :" + key);  
            System.out.println("value :" + value);  
            System.out.println("------------------------");  
        }  
        
    }

    /**
     * 
     *显示values值
     */
    private static void showValues(Properties props) {
        Enumeration<Object> enu = props.elements();  
        while (enu.hasMoreElements()) {  
            Object value = enu.nextElement();  
            System.out.println(value);  
        }  
        
    }

    /**
     * 
     *显示Keys值
     */
    private static void showKeys(Properties props) {
        Enumeration<?> enu = props.propertyNames();  
        while (enu.hasMoreElements()) {  
            Object key = enu.nextElement();  
            System.out.println(key);  
        }  
    }
    
    /**
     * 
     *显示具体意义的值
     */
    
    private static void showSystemInfo(Properties props) {
       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"));
    }

}
