ServerSocketChannel |

---------------------------------

# ServerSocketChannel 是一个可以监听新进来的TCP连接的通道,

# 就像标准IO中的ServerSocket一样。ServerSocketChannel类在 java.nio.channels包中。

# Demo

ServerSocketChannel serverSocketChannel = ServerSocketChannel.open();

serverSocketChannel.socket().bind(new InetSocketAddress(9999)); //绑定端口

while(true){

SocketChannel socketChannel = serverSocketChannel.accept();

//do something with socketChannel...

}

# accept(); 会一直阻塞线程,直到有新的客户端连接进来

---------------------------------

ServerSocketChannel-非阻塞模式 |

---------------------------------

# ServerSocketChannel可以设置成非阻塞模式。

# 在非阻塞模式下，accept() 方法会立刻返回，如果还没有新进来的连接,返回的将是null。 因此，需要检查返回的SocketChannel是否是null.

# Demo

ServerSocketChannel serverSocketChannel = ServerSocketChannel.open();

serverSocketChannel.socket().bind(new InetSocketAddress(9999));

serverSocketChannel.configureBlocking(false); //设置为非阻塞模式

while(true){

SocketChannel socketChannel = serverSocketChannel.accept();

if(socketChannel != null){

//do something with socketChannel...

}

}
