java序列号获取

1. java 怎么获取 U盘的序列号

这种一般是C去获取。java用jni或者command 调用。

2. java代码怎么获取数字的证书那一串20位指纹

通过JAVA来读取数字证书的方法获取20位指纹：
CARead.java文件代码：
public class CARead extends JPanel {
private String CA_Name;
private String CA_ItemData[][] = new String[9][2];
private String[] columnNames = { "证书字段标记", "内容" };
public CARead(String CertName) {
CA_Name = CertName;
/* 三个Panel用来显示证书内容 */
JTabbedPane tabbedPane = new JTabbedPane();
JPanel panelNormal = new JPanel();
tabbedPane.addTab("普通信息", panelNormal);
JPanel panelAll = new JPanel();
panelAll.setLayout(new BorderLayout());
tabbedPane.addTab("所有信息", panelAll);
JPanel panelBase64 = new JPanel();
panelBase64.setLayout(new BorderLayout());
tabbedPane.addTab("Base64编码形式的信息", panelBase64);
/野姿* 读取证书常规信息 */
Read_Normal(panelNormal);
/* 读取证书文件字符串表示内容 */
Read_Bin(panelAll);
/* 以Base64编码颂庆绝形式读取证书文件的信息 */
Read_Raw(panelBase64);
tabbedPane.setSelectedIndex(0);
setLayout(new GridLayout(1, 1));
add(tabbedPane);
}
private int Read_Normal(JPanel panel) {
String Field;
try {
CertificateFactory certificate_factory = CertificateFactory
.getInstance("X.509");
FileInputStream file_inputstream = new FileInputStream(CA_Name);
X509Certificate x509certificate = (X509Certificate) certificate_factory
.generateCertificate(file_inputstream);
Field = x509certificate.getType();
CA_ItemData[0][0] = "类型";
CA_ItemData[0][1] = Field;
Field = Integer.toString(x509certificate.getVersion());
CA_ItemData[1][0] = "版本";
CA_ItemData[1][1] = Field;
Field = x509certificate.getSubjectDN().getName();
CA_ItemData[2][0] = "标题";
CA_ItemData[2][1] = Field;
Field=x509certificate.getNotBefore().toString();//得到开始有效日期
CA_ItemData[3][0] = "开始有效日期";
CA_ItemData[3][1] = Field;
Field=x509certificate. getNotAfter().toString();//得到截止日期
CA_ItemData[4][0] = "截差槐止日期";
CA_ItemData[4][1] = Field;
Field=x509certificate.getSerialNumber().toString(16);//得到序列号
CA_ItemData[5][0] = "序列号";
CA_ItemData[5][1] = Field;

CA_ItemData[8][0] = "公钥算法";
CA_ItemData[8][1] = Field;
//关闭输入流对象
file_inputstream.close();
final JTable table = new JTable(CA_ItemData, columnNames);
TableColumn tc = null; //表格列控制
tc = table.getColumnModel().getColumn(1);//得到表头
tc.setPreferredWidth(600);//设置宽度
panel.add(table);//增加到布局面板
} catch (Exception exception) {
exception.printStackTrace(); //异常捕获、
return -1;
}
return 0;
}
//读取二进制指纹文件
private int Read_Bin(JPanel panel) {
try {

3. 请教高手：java如何读取硬盘的序列号

以下是JAVA获取硬盘序列号的一种方法，仅供参考：

StringHDserialnumber=getHdSerialInfo();
(){
Stringline="";
StringHdSerial="";//定义变量硬盘序列号
try{
Processproces=Runtime.getRuntime().exec("cmd/cdirc:");//获取命令行参数
BufferedReaderbuffreader=newBufferedReader(
newInputStreamReader(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;
//System.out.println(HdSerial);
}
}
}catch(IOExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
returnHdSerial;//返回硬盘序列号卷的序列非物理
}

4. 跪求在JAVA里如何获得CPU的序列号，和硬盘的序列号。

利用Runtime call操作系统的命令，具体的命令取决于不同的操作系统，注意不要调用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])这个接口，不然复杂命令的执行会有问题。例子如下（拿cpu个数，其他类似）：
定义命令：
WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊
SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};
AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};
HPUXCmd = {"/bin/sh", "-c", "echo \"map\" | /usr/sbin/cstm | grep CPU | wc -l "};
LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};

然后判断系统：
os = System.getProperty("os.name").toLowerCase();

根据不同的操作系统call不同的命令。
