RabbitMQ整合Spring Booot【生产者事务确认机制】

package com.toov5.amqp;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.toov5.utils.MQConnectionUtils;

public class Producer {
    // 队列名称
    private static final String UEUE_NAME = "test_queue";

    public static void main(String[] args) throws IOException, TimeoutException {
        // 创建新的连接
        Connection connection = MQConnectionUtils.newConnection();
        // 创建Channel
        Channel channel = connection.createChannel();
        // 创建队列
        channel.queueDeclare(UEUE_NAME, false, false, false, null);
        channel.basicQos(1); // 保证 取一个消费
            try {
                channel.txSelect();    //开启事务
                // 创建message
                String msg = "toov5_message";
                System.out.println("生产者投递消息" + msg );
                // 生产者发送消息
                channel.basicPublish("", UEUE_NAME, null, msg.getBytes());
                int i = 1/0;
                channel.txCommit();   //提交事务
            } catch (Exception e) {
                System.out.println("生产者消息事务已经回滚");
                channel.txRollback();   //回滚事务
            }finally {
                // 关闭通道和连接
                channel.close();
                connection.close();

            }            
            
        }
    
    }

consumer:

package com.toov5.amqp;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.AMQP.BasicProperties;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;
import com.toov5.utils.MQConnectionUtils;

public class Consumer1 {
  
     //队列名称
        private static final String QUEUE_NAME = "test_queue";
        
        public static void main(String[] args) throws IOException, TimeoutException {
            System.out.println("消费者启动..........1");
            //创建新的连接
        Connection connection = MQConnectionUtils.newConnection();
           //创建Channel
            final Channel channel = connection.createChannel();
            // 消费者关联队列
             channel.queueDeclare(QUEUE_NAME, false, false, false, null);
             channel.basicQos(1);
              DefaultConsumer defaultConsumerr = new DefaultConsumer(channel) {
                  //监听获取消息
                    @Override
                    public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
                            byte[] body) throws IOException {
                        String msg =new String(body,"UTF-8");
                        System.out.println("消费者获取生产者消息："+msg);
                        try {
                            //模拟应答等待时间
                            Thread.sleep(1000);
                        } catch (Exception e) {
                            
                        }finally {
                           channel.basicAck(envelope.getDeliveryTag(), false);  //手动应答 告诉消息队列服务器 消费成功
                        }
                    }
              };
            //牵手模式设置  默认自动应答模式  true:自动应答模式  
              channel.basicConsume(QUEUE_NAME, false, defaultConsumerr);//    fanse手动应答          

        }
}

结果：

上面可以做个AOP~~

 可以参考下 Confirm模式
