怎样对RabbitMQ消息进行抓包

**第一步 ：设置过滤条件**

RabbitMQ的过滤条件是amqp

**第二步：运行RabbitMQ程序**

package com.rabbitmq.msgdirection.alternateexchange;
    
    
    import com.rabbitmq.client.AMQP;
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.ReturnListener;
    import com.rabbitmq.util.ConnectionUtils;
    import lombok.extern.slf4j.Slf4j;
    
    
    import java.io.IOException;
    import java.util.HashMap;
    import java.util.Map;
    import java.util.concurrent.TimeoutException;
    
    
    import static com.rabbitmq.common.Constant.NUM3;
    
    
    /**
    * 备用交换器
    */
    @Slf4j
    public class AlternateExchange {
        public static void main( String[] args ) {
            try {
                // 创建连接
                Connection connection = ConnectionUtils.getConnection();
                // 创建信道
                Channel channel = connection.createChannel();
                // 备份路由器放到Map
                Map<String, Object> arg = new HashMap<String, Object>(NUM3);
                arg.put("alternate-exchange", "myAe");
    
    
                // 创建正常交换器，最后一个参数会指定备份路由器
                channel.exchangeDeclare("normalExchange", "direct",
                        true, false, false, arg);
                // 创建备份交换器
                channel.exchangeDeclare("myAe", "fanout",
                        true, false, false, null);
                // 声明正常交换器绑定的的队列
                channel.queueDeclare("normalQueue", true, false, false, null);
                // 正常队列的绑定
                channel.queueBind("normalQueue", "normalExchange", "normalKey");
                // 声明备份交换器绑定的队列
                channel.queueDeclare("unroutingQueue", true, false, false, null);
                // 备份交换器队列的绑定
                channel.queueBind("unroutingQueue", "myAe", "");
                // 定义要发送的消息
                String message = "hello test";
                // 能正常路由的消息的发送
                channel.basicPublish("normalExchange", "normalKey",
                        null, message.getBytes());
                // 不能正常路由消息的发送
    //            channel.basicPublish("normalExchange", "notnormalKey",
    //                    null, message.getBytes());
                // 观察消息是否会回退到生产者
                channel.addReturnListener(new ReturnListener() {
                    /**
                     * broker(代理服务器)发出basic.return方法之后，就会回调handleReturn方法，
                     * 在这个方法里面我们就可以进行消息的重新发布操作
                     * @param replyCode 312
                     * @param replyText NO_ROUTE：表示消息并没有路由到合适的队列中
                     * @param exchange 交换器
                     * @param routingKey 路由键
                     * @param properties 相关属性
                     * @param body 消息体
                     * @throws IOException
                     */
                    @Override
                    public void handleReturn( int replyCode, String replyText, String exchange, String routingKey,
                                              AMQP.BasicProperties properties, byte[] body ) throws IOException {
                        String message = new String(body);
                        log.info("replyCode:  " + replyCode);
                        log.info("replyText:  " + replyText);
                        log.info("Basic.Return返回的结果:  " + message);
                    }
                });
    
                ConnectionUtils.close(channel, connection);
            } catch (IOException e) {
                log.info("catch IOException");
            } catch (TimeoutException e) {
                log.info("catch TimeoutException");
            }
        }
    }

**第三步：抓包出结果，根据协议分析抓包内容**
