这里主要是记录下java如何调用vbscript取得计算机信息代码小例子，不说概念性东西.

下面的vbs文件，可以直接点击运行。有兴趣的同学可百度了解vbscript资料.

cpu.vbs

Set wmiObj = GetObject("winmgmts:")For Each cpu in wmiObj.ExecQuery("SELECT * FROM Win32_Processor")    CALL WScript.Echo ("SysLoadPercentage: " & cpu.LoadPercentage)Next

disk.vbs

Set wmiObj = GetObject("winmgmts:")For Each disk in wmiObj.ExecQuery("SELECT * FROM Win32_LogicalDisk WHERE drivetype = 3")    diskInfo = "LogicalDisk: " & disk.Name & ", " & disk.size & ", " & disk.freespace & ", " & disk.filesystem    Call WScript.Echo(diskInfo)Next

io.vbs

Const C_COMMA = ", "Set wmiObj = GetObject("winmgmts:")Set refersher = CreateObject("WbemScripting.SWbemRefresher")Set disks = refersher.AddEnum(wmiObj, "Win32_PerfFormattedData_PerfDisk_LogicalDisk").objectSetrefersher.RefreshWScript.Sleep 100refersher.RefreshFor Each disk in disks    diskIoInfoStr = "DiskIO: " & disk.Name & C_COMMA & disk.DiskBytesPerSec  & C_COMMA & disk.DiskReadBytesPerSec  & C_COMMA & disk.DiskWriteBytesPerSec    Call WScript.Echo (diskIoInfoStr)Next

momery.vbs

Set wmiObj = GetObject("winmgmts:")For Each sys In wmiObj.Execquery("Select * From Win32_OperatingSystem")    WScript.Echo "TotalPhysicalMemory: " & sys.TotalVisibleMemorySize    WScript.Echo "FreePhysicalMemory: " & sys.FreePhysicalMemoryNext

process.vbs

Set wmiObj = GetObject("winmgmts:")For Each sys In wmiObj.Execquery("Select * From Win32_OperatingSystem")    WScript.Echo "ProcessCount: " & sys.NumberOfProcessesNext

这里主要取了CPU、内存等几个信息，大家利用WMI的API或者借助JSEDIT获取到更多的信息。下面列出了常用信息的类：Win32_Processor                        // CPU 处理器Win32_PhysicalMemory                   // 物理内存Win32_Keyboard                         // 键盘Win32_PointingDevice                   // 点输入设备，如鼠标Win32_DiskDrive                        // 硬盘驱动器Win32_CDROMDrive                       // 光盘驱动器Win32_BaseBoard                        // 主板Win32_BIOS                             // BIOS 芯片Win32_ParallelPort                     // 并口Win32_SerialPort                       // 串口Win32_SoundDevice                      // 多媒体设置Win32_USBController                    // USB 控制器Win32_NetworkAdapter                   // 网络适配器Win32_NetworkAdapterConfiguration      // 网络适配器设置Win32_Printer                          // 打印机Win32_PrinterConfiguration             // 打印机设置Win32_PrintJob                         // 打印机任务Win32_TCPIPPrinterPort                 // 打印机端口Win32_POTSModem                        // MODEMWin32_POTSModemToSerialPort            // MODEM 端口Win32_DesktopMonitor                   // 显示器Win32_VideoController                  // 显卡细节。Win32_VideoSettings                    // 显卡支持的显示模式。Win32_TimeZone                         // 时区Win32_SystemDriver                     // 驱动程序Win32_DiskPartition                    // 磁盘分区Win32_LogicalDisk                      // 逻辑磁盘Win32_LogicalMemoryConfiguration       // 逻辑内存配置Win32_PageFile                         // 系统页文件信息Win32_PageFileSetting                  // 页文件设置Win32_BootConfiguration                // 系统启动配置Win32_OperatingSystem                  // 操作系统信息Win32_StartupCommand                   // 系统自动启动程序Win32_Service                          // 系统安装的服务Win32_Group                            // 系统管理组Win32_GroupUser                        // 系统组帐号Win32_UserAccount                      // 用户帐号Win32_Process                          // 系统进程Win32_Thread                           // 系统线程Win32_Share                            // 共享Win32_NetworkClient                    // 已安装的网络客户端Win32_NetworkProtocol                  // 已安装的网络协议
