AsynchronousFileChannel引发java.nio.file.NoSuchFileException
我正在玩JavaNIO2,我编写了一个简单的应用程序,应该创建一个文件并将内容写入其中,但我得到的文件不存在异常AsynchronousFileChannel引发java.nio.file.NoSuchFileException,java,nio,Java,Nio,我正在玩JavaNIO2,我编写了一个简单的应用程序,应该创建一个文件并将内容写入其中,但我得到的文件不存在异常 ByteBuffer buffer = ByteBuffer.wrap("jhkjhkhjkhkjhkjhkjhkjhkhkjhkjhkjh".getBytes()); Path path = Paths.get("F:", "dummyFile.txt"); try(AsynchronousFileChannel asynchronousFileChannel
ByteBuffer buffer = ByteBuffer.wrap("jhkjhkhjkhkjhkjhkjhkjhkhkjhkjhkjh".getBytes());

while (!future.isDone()) {

System.out.println(e.toString());

try(异步文件通道异步文件通道=
AsynchronousFileChannel.open(路径,StandardOpenOption.CREATE\u NEW)){
Future-Future=asynchronousFileChannel.write(缓冲区,0);
而(!future.isDone()){
System.out.println(“等待”);
}
System.out.println(String.format(“Done-bytes writed%d”,future.get());
}捕获(例外e){
System.out.println(例如toString());
}
好的,我发现我应该添加write选项
AsynchronousFileChannel asynchronousFileChannel =
AsynchronousFileChannel.open(path, StandardOpenOption.CREATE, StandardOpenOption.WRITE)
