springboot中实现AioQuickClient

在Spring Boot中实现AioQuickClient，可以使用Netty框架提供的异步非阻塞I/O操作。下面是一个简单的示例代码，你可以根据自己的需求进行修改：

1. 首先，在pom.xml中添加Netty依赖：

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.63.Final</version>
</dependency>

2. 创建一个AioQuickClient类，用于连接服务器、发送和接收数据：

import io.netty.bootstrap.Bootstrap;
import io.netty.buffer.ByteBuf;
import io.netty.buffer.Unpooled;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.ChannelInitializer;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.SocketChannel;
import io.netty.channel.socket.nio.NioSocketChannel;
import io.netty.handler.codec.ByteToMessageDecoder;
import io.netty.handler.codec.MessageToByteEncoder;
import io.netty.handler.codec.string.StringDecoder;
import io.netty.handler.codec.string.StringEncoder;
import java.nio.charset.Charset;
import java.util.List;

public class AioQuickClient {

    private String host;
    private int port;
    private Bootstrap bootstrap;
    private EventLoopGroup workerGroup;
    private ChannelFuture channelFuture;

    public AioQuickClient(String host, int port) {
        this.host = host;
        this.port = port;
        init();
    }

    private void init() {
        bootstrap = new Bootstrap();
        workerGroup = new NioEventLoopGroup();
        bootstrap.group(workerGroup)
                .channel(NioSocketChannel.class)
                .option(ChannelOption.SO_KEEPALIVE, true)
                .handler(new ChannelInitializer<SocketChannel>() {
                    @Override
                    protected void initChannel(SocketChannel ch) throws Exception {
                        ch.pipeline().addLast(new StringEncoder(Charset.forName("UTF-8")));
                        ch.pipeline().addLast(new StringDecoder(Charset.forName("UTF-8")));
                        // 添加自定义编码器
                        ch.pipeline().addLast(new MyEncoder());
                        // 添加自定义解码器
                        ch.pipeline().addLast(new MyDecoder());
                        // 添加自定义处理器
                        ch.pipeline().addLast(new MyHandler());
                    }
                });
    }

    public void connect() throws InterruptedException {
        channelFuture = bootstrap.connect(host, port).sync();
    }

    public void send(String message) {
        ByteBuf byteBuf = Unpooled.copiedBuffer(message, Charset.forName("UTF-8"));
        channelFuture.channel().writeAndFlush(byteBuf);
    }

    public void close() {
        workerGroup.shutdownGracefully();
    }

    // 自定义编码器
    private static class MyEncoder extends MessageToByteEncoder<String> {

        @Override
        protected void encode(ChannelHandlerContext ctx, String msg, ByteBuf out) throws Exception {
            out.writeInt(msg.length());
            out.writeBytes(msg.getBytes());
        }
    }

    // 自定义解码器
    private static class MyDecoder extends ByteToMessageDecoder {

        @Override
        protected void decode(ChannelHandlerContext ctx, ByteBuf in, List<Object> out) throws Exception {
            if (in.readableBytes() >= 4) {
                int length = in.readInt();
                if (in.readableBytes() < length) {
                    in.resetReaderIndex();
                    return;
                }
                byte[] bytes = new byte[length];
                in.readBytes(bytes);
                String message = new String(bytes, Charset.forName("UTF-8"));
                out.add(message);
            }
        }
    }

    // 自定义处理器
    private static class MyHandler extends SimpleChannelInboundHandler<String> {

        @Override
        protected void channelRead0(ChannelHandlerContext ctx, String msg) throws Exception {
            System.out.println("收到服务器消息：" + msg);
        }
    }
}

3. 在Spring Boot的启动类中创建AioQuickClient实例并连接服务器：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);

        AioQuickClient client = new AioQuickClient("127.0.0.1", 8888);
        try {
            client.connect();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        client.send("Hello, server!");
        client.close();
    }
}

在以上示例中，我们使用了Netty的自定义编码器、解码器和处理器来处理数据的编解码和业务逻辑。你可以根据自己的需求进行相应的修改。
