Selector.select()

Netty的底层依然是依赖于JDK的NIO . 开发NIO服务端的代码如下所示
import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.*;
import java.util.Iterator;
import java.util.Set;

public class Server {

// 缓冲区的大小
private static final int BUFFER_SIZE = 1024;

// 缓冲区
private static ByteBuffer buffer = ByteBuffer.allocate(BUFFER_SIZE);

// 选择器
private static

Selector.select()最先出现在Python成神之路。
