在花了几个小时上网并编码之后，我找到了使用JNA来获取文件的版本信息的解决方案。
import com.sun.jna.Library;import com.sun.jna.Memory;import com.sun.jna.Native;import com.sun.jna.Pointer;import com.sun.jna.ptr.IntByReference;import com.sun.jna.ptr.PointerByReference;import com.sun.jna.win32.W32APIOptions;import java.io.IOException;public class FileVersionInfo{ interface Version extends Library { Version INSTANCE = (Version) Native.loadLibrary("Version", Version.class, W32APIOptions.UNICODE_OPTIONS); public int GetFileVersionInfoSizeW(String lptstrFilename, int dwDummy); public boolean GetFileVersionInfoW(String lptstrFilename, int dwHandle, int dwLen, Pointer lpData); public int VerQueryValueW(Pointer pBlock, String lpSubBlock, PointerByReference lplpBuffer, IntByReference puLen); } static class VS_FIXEDFILEINFO extends com.sun.jna.Structure { public int dwSignature; public int dwStrucVersion; public int dwFileVersionMS; public int dwFileVersionLS; public int dwProductVersionMS; public int dwProductVersionLS; public int dwFileFlagsMask; public int dwFileFlags; public int dwFileOS; public int dwFileType; public int dwFileSubtype; public int dwFileDateMS; public int dwFileDateLS;public VS_FIXEDFILEINFO(com.sun.jna.Pointer p){ super(p);} } public static void main(String[] args) throws IOException { int dwDummy = 0; int versionlength = Version.INSTANCE.GetFileVersionInfoSizeW( "C:\Test\chromeinstall.exe", dwDummy); byte[] bufferarray = new byte[versionlength]; Pointer lpData = new Memory(bufferarray.length); PointerByReference lplpBuffer = new PointerByReference(); IntByReference puLen = new IntByReference(); boolean FileInfoResult = Version.INSTANCE.GetFileVersionInfoW( "C:\Test\chromeinstall.exe", 0, versionlength, lpData); System.out.println(FileInfoResult); int verQueryVal = Version.INSTANCE.VerQueryValueW(lpData, "\", lplpBuffer, puLen); VS_FIXEDFILEINFO lplpBufStructure = new VS_FIXEDFILEINFO( lplpBuffer.getValue()); lplpBufStructure.read(); short[] rtnData = new short[4]; rtnData[0] = (short) (lplpBufStructure.dwFileVersionMS >> 16); rtnData[1] = (short) (lplpBufStructure.dwFileVersionMS & 0xffff); rtnData[2] = (short) (lplpBufStructure.dwFileVersionLS >> 16); rtnData[3] = (short) (lplpBufStructure.dwFileVersionLS & 0xffff); for (int i = 0; i < rtnData.length; i++) { System.out.println(rtnData[i]); }}
