#JNI获得硬盘信息

本文介绍了一种使用Java跨平台获取硬盘序列号的方法，通过JNI调用C++代码实现对不同Windows系统的IDE硬盘进行识别，并读取其序列号等信息。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

以下是获取硬盘序列号,CPU 道理一样.

// Sys.java

public class Sys

{

public static native void showHDSerial();

static {

System.loadLibrary("Sys");

}

public static void main(String[] args)

{

showHDSerial();

}

1) 编译

javac Sys.java

2)生成 .h 文件

javah -jni Sys

3)打开VC->文件->新建->工程->Win32 DLL (这里简写了)

4)写入工程名;Sys 创建空白工程

5)将Sys.h,jni.h 添加到工程中(其中jni.h在[JAVA_HOME]\include 下).

6)创建Sys.cpp 文件.文件内容如下:

// Sys.cpp

#include "jni.h"

#include <windows.h>

#include <iostream.h>

#include <stdio.h>

#define DFP_GET_VERSION 0x00074080

#define DFP_RECEIVE_DRIVE_DATA 0x0007c088

BYTE bCommandReg; // Actual IDE command.

BYTE bReserved; // reserved for future use. Must be zero.

} IDEREGS, *PIDEREGS, *LPIDEREGS;

typedef struct _SENDCMDINPARAMS {

DWORD cBufferSize; // Buffer size in bytes

IDEREGS irDriveRegs; // Structure with drive register values.

// command to (0,1,2,3).

} SENDCMDINPARAMS, *PSENDCMDINPARAMS, *LPSENDCMDINPARAMS;

typedef struct _DRIVERSTATUS {

BYTE bDriverError; // Error code from driver,

// or 0 if no error.

BYTE bIDEStatus; // Contents of IDE Error register.

// Only valid when bDriverError

// is SMART_IDE_ERROR.

BYTE bReserved[2]; // Reserved for future expansion.

DWORD dwReserved[2]; // Reserved for future expansion.

} DRIVERSTATUS, *PDRIVERSTATUS, *LPDRIVERSTATUS;

typedef struct _SENDCMDOUTPARAMS {

DWORD cBufferSize; // Size of bBuffer in bytes

DRIVERSTATUS DriverStatus; // Driver status structure.

BYTE bBuffer[512]; // Buffer of arbitrary length

// in which to store the data read from the drive.

} SENDCMDOUTPARAMS, *PSENDCMDOUTPARAMS, *LPSENDCMDOUTPARAMS;

}

7)新建Sys.def 文件,内容如下

EXPORTS

Java_Sys_showHDSerial

编译Sys 工程,生成Sys.dll

9)将Sys.dll 拷到Sys.class 同目录下

10)运行

java Sys

得到如下结果(本人机器)

F:\>java Sys

Module Number:SAMSUNG SP0802N

Firmware rev:TK100-28

Serial Number: S00JJ50Y418303

Capacity:76293M
