public class ClientHandlerInitializer extends ChannelInitializer<Channel> {

@Override
protected void initChannel(Channel ch) throws Exception {
    ch.pipeline()
            .addLast(new IdleStateHandler(0, 10, 0))
            .addLast(new ProtobufVarint32FrameDecoder())
            .addLast(new ProtobufDecoder(MessageBase.Message.getDefaultInstance()))
            .addLast(new ProtobufVarint32LengthFieldPrepender())
            .addLast(new ProtobufEncoder())
            .addLast(new HeartbeatHandler())
            .addLast(new NettyClientHandler());
}

}

addLast(new HeartbeatHandler(new NettyClient()))，创建一个客户端进行连接就行，你可以尝试下
