JAVA获取系统相关信息

获取JRE系统相关参数

 java 通过System.getProperties()获取系统参数

  Properties props=System.getProperties(); //系统属性

//   Set<Object> keySet = sysProperty.keySet();
//   for (Object object : keySet) {
//    String property = sysProperty.getProperty(object.toString());
//    System.out.println(object.toString()+" : "+property);
//   }
   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"));

二、获取系统环境变量

　　Map<String, String> getenv = System.getenv();

三、获取IP、 计算机名、MAC、 硬盘卷序号

package com.geocompass.geosearch.tools;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Properties;

/**
 * 获取当前系统信息
 * @author gxsn
 *
 */
public class SystemInfo {
    //当前实例
    private static SystemInfo currentSystem=null;
    private  InetAddress localHost=null;
    
    private SystemInfo()
    {
        try {
            localHost = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    /**
     * 单例模式获取对象
     * @return
     */
    public static SystemInfo getInstance()
    {
        if(currentSystem==null)
            currentSystem= new SystemInfo();
        return currentSystem;
    }
    /**
     * 本地IP
     * @return IP地址
     */
    public String getIP()
    {
        String ip=localHost.getHostAddress();
        return ip;
    }
    /**
     * 获取用户机器名称
     * @return
     */
    public String getHostName()
    {
        return localHost.getHostName();
    }
    
    /**
     * 获取C盘卷 序列号
     * @return
     */
    public String getDiskNumber()
    {
          String line = "";
          String HdSerial = "";//记录硬盘序列号

          try {

           Process proces = Runtime.getRuntime().exec("cmd /c dir c:");//获取命令行参数
           BufferedReader buffreader = new BufferedReader(
             new InputStreamReader(proces.getInputStream()));

           while ((line = buffreader.readLine()) != null) {

            if (line.indexOf("卷的序列号是 ") != -1) {  //读取参数并获取硬盘序列号

             HdSerial = line.substring(line.indexOf("卷的序列号是 ")
               + "卷的序列号是 ".length(), line.length());
             break;
            }
           }

          } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
          }

          return HdSerial;
    }
    
    /**
     * 获取Mac地址
     * @return Mac地址，例如：F0-4D-A2-39-24-A6
     */
    public String getMac()
    {
        NetworkInterface byInetAddress;
        try {
            byInetAddress = NetworkInterface.getByInetAddress(localHost);
            byte[] hardwareAddress = byInetAddress.getHardwareAddress();
            return getMacFromBytes(hardwareAddress);
        } catch (SocketException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;        
    }
    
    /**
     * 获取当前系统名称
     * @return 当前系统名，例如： windows xp
     */
    public String getSystemName()
    {
        Properties sysProperty = System.getProperties();
        //系统名称
        String systemName=sysProperty.getProperty("os.name");
        return systemName;
    }
    
    private  String getMacFromBytes(byte[] bytes)
    {
        StringBuffer mac=new StringBuffer();
        byte currentByte;
        boolean first=false;
        for (byte b : bytes) {
            if(first)
            {
                mac.append("-");    
            }
            currentByte=(byte)((b&240)>>4);
            mac.append(Integer.toHexString(currentByte));
            currentByte=(byte)(b&15);
            mac.append(Integer.toHexString(currentByte));
            first=true;
        }
        return mac.toString().toUpperCase();
    }
}

四、执行系统命令 jar包

Sigar.jar  参见：http://sourceforge.net/projects/sigar/files/

五、获取端口号

  public static String getOpenPorts() {

    String line = "";
    String HdSerial = "";//记录硬盘序列号
    StringBuffer buf = new StringBuffer("");
    try {

     Process proces = Runtime.getRuntime().exec("cmd /c netstat -a");//获取命令行参数
     BufferedReader buffreader = new BufferedReader(
       new InputStreamReader(proces.getInputStream()));
   
     while ((line = buffreader.readLine()) != null) {
      buf.append(line+"\n");
      System.out.println(line);
      }

    } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }

    return buf.toString();
   }

   VBS文件获取硬盘系列号

 public static String getSerialNumber(String drive) {
    String result = "";
      try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new java.io.FileWriter(file);

        String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
                    +"Set colDrives = objFSO.Drives\n"
                    +"Set objDrive = colDrives.item(\"" + drive + "\")\n"
                    +"Wscript.Echo objDrive.SerialNumber";  // see note
        fw.write(vbs);
        fw.close();
        Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
        BufferedReader input =
          new BufferedReader
            (new InputStreamReader(p.getInputStream()));
        String line;
        while ((line = input.readLine()) != null) {
           result += line;
        }
        input.close();
      }
      catch(Exception e){
          e.printStackTrace();
      }
      return result.trim();
    }
