Java 异步NIO写文件,无队列线程池方案

java.nio.channels.AsynchronousChannel提供了异步写文件方法，

具体代码如下：

1public static void syncWrite(String path){
2    File file = new File(path+"warn.log");
3            if(!file.exists()) {
4                file.createNewFile();
5            }
6            Path pathSyn = Paths.get(path+line+"warn.log");
7            try {
8                AsynchronousFileChannel channel = AsynchronousFileChannel.open(pathSyn, StandardOpenOption.WRITE);
9                ByteBuffer buffer = ByteBuffer.allocate(1024);
10                buffer = ByteBuffer.wrap(clientSender.getBytes("utf-8"));
11                Future<Integer> future = channel.write(buffer, channel.size());
12                channel.force(true);
13                while (!future.isDone());
14                buffer.clear();
15                channel.close();
16            } catch (Exception e) {
17                e.printStackTrace();
18            }    
19}
