httprequesthandler -- http请求处理类 textwebsocketframehandler -- 对应text消息的处理类 websocketserver -- 系统主类 websocketserverinitializer -- 服务主程序的初始化类 websocketserver 类代码： import io.netty.bootstrap.serverbootstrap; import io.netty.channel.channelfuture; import io.netty.channel.channeloption; import io.netty.channel.eventloopgroup; import io.netty.channel.nio.nioeventloopgroup; import io.netty.channel.socket.nio.nioserversocketchannel; public final class websocketserver { private int port = 0; public websocketserver(int port) { this.port = port; } public void run() throws exception { eventloopgroup bossgroup = new nioeventloopgroup(); eventloopgroup workergroup = new nioeventloopgroup(); try { serverbootstrap b = new serverbootstrap(); b.group(bossgroup, workergroup) .channel(nioserversocketchannel.class) .childhandler(new websocketserverinitializer()) .option(channeloption.so_backlog, 128) .childoption(channeloption.so_keepalive, true); system.out.println("websocketchatserver 启动了"); // 绑定端口，开始接收进来的连接 channelfuture f = b.bind(port).sync(); // 等待服务器 socket 关闭 。在这个例子中，这不会发生，但你可以优雅地关闭你的服务器。 f.channel().closefuture().sync(); } finally { workergroup.shutdowngracefully(); bossgroup.shutdowngracefully(); system.out.println("websocketchatserver 关闭了"); } }
