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(); }
