獲取JRE系統相關參數

?java 通過System.getProperties()獲取系統參數

? Properties props=System.getProperties(); //系統屬性

//???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的運行環境版本："+props.getProperty("java.version"));
?? System.out.println("Java的運行環境供應商："+props.getProperty("java.vendor"));
?? System.out.println("Java供應商的URL："+props.getProperty("java.vendor.url"));
?? System.out.println("Java的安裝路徑："+props.getProperty("java.home"));
?? System.out.println("Java的虛擬機規范版本："+props.getProperty("java.vm.specification.version"));
?? System.out.println("Java的虛擬機規范供應商："+props.getProperty("java.vm.specification.vendor"));
?? System.out.println("Java的虛擬機規范名稱："+props.getProperty("java.vm.specification.name"));
?? System.out.println("Java的虛擬機實現版本："+props.getProperty("java.vm.version"));
?? System.out.println("Java的虛擬機實現供應商："+props.getProperty("java.vm.vendor"));
?? System.out.println("Java的虛擬機實現名稱："+props.getProperty("java.vm.name"));
?? System.out.println("Java運行時環境規范版本："+props.getProperty("java.specification.version"));
?? System.out.println("Java運行時環境規范供應商："+props.getProperty("java.specification.vender"));
?? System.out.println("Java運行時環境規范名稱："+props.getProperty("java.specification.name"));
?? System.out.println("Java的類格式版本號："+props.getProperty("java.class.version"));
?? System.out.println("Java的類路徑："+props.getProperty("java.class.path"));
?? System.out.println("加載庫時搜索的路徑列表："+props.getProperty("java.library.path"));
?? System.out.println("默認的臨時文件路徑："+props.getProperty("java.io.tmpdir"));
?? System.out.println("一個或多個擴展目錄的路徑："+props.getProperty("java.ext.dirs"));
?? System.out.println("操作系統的名稱："+props.getProperty("os.name"));
?? System.out.println("操作系統的構架："+props.getProperty("os.arch"));
?? System.out.println("操作系統的版本："+props.getProperty("os.version"));
?? System.out.println("文件分隔符："+props.getProperty("file.separator"));?? //在 unix 系統中是＂／＂
?? System.out.println("路徑分隔符："+props.getProperty("path.separator"));?? //在 unix 系統中是＂:＂
?? System.out.println("行分隔符："+props.getProperty("line.separator"));?? //在 unix 系統中是＂/n＂
?? System.out.println("用戶的賬戶名稱："+props.getProperty("user.name"));
?? System.out.println("用戶的主目錄："+props.getProperty("user.home"));
?? System.out.println("用戶的當前工作目錄："+props.getProperty("user.dir"));

二、獲取系統環境變量

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

?

三、獲取IP、 計算機名、MAC、 硬盤卷序號

?

import?java.io.InputStreamReader;
import?java.net.InetAddress;

????????????mac.append(Integer.toHexString(currentByte));
????????????first=true;
????????}
????????return?mac.toString().toUpperCase();
????}
}

四、執行系統命令 jar包

Sigar.jar? 參見：http://sourceforge.net/projects/sigar/files/

?

五、獲取端口號

?

? public static String getOpenPorts() {

??? String line = "";
??? String HdSerial = "";//記錄硬盤序列號
??? StringBuffer buf = new StringBuffer("");
??? try {

???? Process proces = Runtime.getRuntime().exec("cmd /c netstat -a");//獲取命令行參數
???? 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文件獲取硬盤系列號

?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();
??? }
