HOME dizini kavramı, Windows söz konusu olduğunda biraz belirsiz görünüyor. Eğer ortam değişkenleri (homedrive / homepath / userprofıle) yeterli değildir, sen aracılığıyla yerli işlevlerini kullanarak başvurmak gerekebilir JNI veya JNA . SHGetFolderPath , Belgelerim (CSIDL_PERSONAL) veya Yerel Ayarlar \ Uygulama Verileri (CSIDL_LOCAL_APPDATA) gibi özel klasörleri almanıza olanak tanır .
Örnek JNA kodu:
public class PrintAppDataDir {
public static void main(String[] args) {
if (com.sun.jna.Platform.isWindows()) {
HWND hwndOwner = null;
int nFolder = Shell32.CSIDL_LOCAL_APPDATA;
HANDLE hToken = null;
int dwFlags = Shell32.SHGFP_TYPE_CURRENT;
char[] pszPath = new char[Shell32.MAX_PATH];
int hResult = Shell32.INSTANCE.SHGetFolderPath(hwndOwner, nFolder,
hToken, dwFlags, pszPath);
if (Shell32.S_OK == hResult) {
String path = new String(pszPath);
int len = path.indexOf('\0');
path = path.substring(0, len);
System.out.println(path);
} else {
System.err.println("Error: " + hResult);
}
}
}
private static Map<String, Object> OPTIONS = new HashMap<String, Object>();
static {
OPTIONS.put(Library.OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);
OPTIONS.put(Library.OPTION_FUNCTION_MAPPER,
W32APIFunctionMapper.UNICODE);
}
static class HANDLE extends PointerType implements NativeMapped {
}
static class HWND extends HANDLE {
}
static interface Shell32 extends Library {
public static final int MAX_PATH = 260;
public static final int CSIDL_LOCAL_APPDATA = 0x001c;
public static final int SHGFP_TYPE_CURRENT = 0;
public static final int SHGFP_TYPE_DEFAULT = 1;
public static final int S_OK = 0;
static Shell32 INSTANCE = (Shell32) Native.loadLibrary("shell32",
Shell32.class, OPTIONS);
