我正在玩java nio 2,我编写了一个简单的应用程序,应该创建一个文件并向其中写入内容,但我收到文件不存在异常
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());
}
最佳答案
好吧,我发现我应该添加写入选项
AsynchronousFileChannel asynchronousFileChannel =
AsynchronousFileChannel.open(path, StandardOpenOption.CREATE, StandardOpenOption.WRITE)
关于java - AsynchronousFileChannel 抛出 java.nio.file.NoSuchFileException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/28786805/
