我想将我的项目中的src文件中的文件复制到我的目录,但是当我导出到runnable jar时它不起作用。
public static void main(String args[]) throws IOException{
FileCopyController fpc = new FileCopyController();
File fileSrc = new File("src/java.exe");
File fileDest = new File("C:/Directory1/java.exe");
fpc.copyFileUsingChannel(fileSrc, fileDest);
}
public void copyFileUsingChannel(File source, File dest) throws IOException {
InputStream is = null;
OutputStream os = null;
try {
is = new FileInputStream(source);
os = new FileOutputStream(dest);
byte[] buffer = new byte[1024];
int length;
while ((length = is.read(buffer)) > 0) {
os.write(buffer, 0, length);
}
} finally {
is.close();
os.close();
}
答案 0 :(得分:2)
尝试这样的事情:
public static void main(String args[]) throws IOException
{
final InputStrean src = getClass().getResourceAsStream("/java.exe");
final Path dest = new File("C:/Directory1/java.exe").toPath();
Files.copy(src, dest, StandardCopyOption.REPLACE_EXISTING);
}
