[英]AsynchronousFileChannel throw java.nio.file.NoSuchFileException
我正在使用java nio 2,並且編寫了一個簡單的應用程序,該應用程序應創建一個文件並向其中寫入內容,但是我得到的文件不存在異常
ByteBuffer buffer = ByteBuffer.wrap("jhkjhkhjkhkjhkjhkjhkjhkhkjhkjhkjh".getBytes());
Path path = Paths.get("F:", "dummyFile.txt");
try(AsynchronousFileChannel asynchronousFileChannel =
AsynchronousFileChannel.open(path, StandardOpenOption.CREATE_NEW)) {
Future<Integer> future = asynchronousFileChannel.write(buffer, 0);
while (!future.isDone()) {
System.out.println("waiting");
}
System.out.println(String.format("Done - bytes written %d", future.get()));
} catch (Exception e) {
System.out.println(e.toString());
}
好的,我發現我應該添加寫選項
AsynchronousFileChannel asynchronousFileChannel =
AsynchronousFileChannel.open(path, StandardOpenOption.CREATE, StandardOpenOption.WRITE)
