JAVA基础知识之网络编程——-基于AIO的异步Socket通信

异步IO

下面摘子李刚的《疯狂JAVA讲义》

按照POSIX标准来划分IO，分为同步IO和异步IO。对于IO操作分为两步，1）程序发出IO请求。 2）完成实际的IO操作。

阻塞IO和非阻塞IO都是针对第一步来划分的，如果发出IO请求会阻塞线程，就是阻塞IO，否则就是非阻塞IO。

同步IO和非同步IO是针对第二步来说的，如果实际IO操作是由操作系统完成，再返回给程序，就是异步IO。

如果实际的IO需要程序本身去执行，会阻塞线程，就是同步IO。

JAVA7的NIO.2提供了异步的channel， 从而使网络Socket的异步通信成为可能。

使用异步IO通信只需要三步，

1. 调用open静态方法创建AsynchronousServerSocketChannel
2. 调用AsynchronousServerSocketChannel的bind方法监听指定IP和端口
3. 调用AsynchronousServerSocketChannel的accept方法接受连接请求

下面是一个简单例子，

服务器端

 package aio;

 import java.io.IOException;
 import java.net.InetSocketAddress;
 import java.nio.ByteBuffer;
 import java.nio.channels.AsynchronousServerSocketChannel;
 import java.nio.channels.AsynchronousSocketChannel;
 import java.util.concurrent.ExecutionException;
 import java.util.concurrent.Future;

 public class Server {
     private static final int PORT = 3002;
     public static void main(String[] args) throws IOException, InterruptedException, ExecutionException {
         try {
             AsynchronousServerSocketChannel serverChannel =  AsynchronousServerSocketChannel.open();
             serverChannel.bind(new InetSocketAddress(PORT));
             while (true) {
                 Future<AsynchronousSocketChannel> future = serverChannel.accept();
                 //获取连接成功之后的AsynchronousSocketChannel
                 AsynchronousSocketChannel socketChannel = future.get();
                 socketChannel.write(ByteBuffer.wrap("你好，这是AIO世界".getBytes("utf-8"))).get();
             }
         } catch(IOException e) {
             e.printStackTrace();
         }
     }
 }

客户端

 package aio;

 import java.io.IOException;
 import java.net.InetSocketAddress;
 import java.nio.ByteBuffer;
 import java.nio.channels.AsynchronousSocketChannel;
 import java.nio.charset.Charset;
 import java.util.concurrent.ExecutionException;

 public class Client {
     private static final int PORT = 3002;
     public static void main(String[] args) throws IOException, InterruptedException, ExecutionException {
         ByteBuffer buff = ByteBuffer.allocate(1024);
         Charset utf = Charset.forName("utf-8");
         try {
             AsynchronousSocketChannel clientChannel = AsynchronousSocketChannel.open();
             clientChannel.connect(new InetSocketAddress("127.0.0.1",PORT)).get();
             buff.clear();
             clientChannel.read(buff).get();
             buff.flip();
             String content = utf.decode(buff).toString();
             System.out.println("服务器信息："+content);
         } catch (IOException ex) {
             ex.printStackTrace();
         }
     }
 }

执行结果，使用一个服务器端和两个客户端测试，
