用JAVA+DLL获取硬盘序列号
// 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>

7)新建Sys.def 文件,内容如下
EXPORTS
Java_Sys_showHDSerial
8)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
