RabbitMq浅试和记录

RabbitMq浅试和记录

本次需求需要同步两库中的company表。
业务代码略过。。。
rabbitmq创建交换机

绑定队列

创建队列

2.发布者代码

	@Autowired
    RabbitTemplate rabbitTemplate;

	@Override
	public void sendMessageCompany(JSONObject messageVo, String routingkey) {
		// 交换机名称 绑定的routingkey 消息
		rabbitTemplate.convertAndSend("company", "hello", messageVo);
	}

3.消费者代码
初始化通道

package com.gold.mtmc.rabbitmq.config;

import com.gold.mtmc.common.contants.enums.RabbitMqEnum;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class HelloExchangeConfig {
	
	private String EXCHANGE = "hello";

	private String QUEUE = "helloqueue";

	private String RoutingKey = "message_hello";

	
	@Bean
	public DirectExchange helloExchange() {
		DirectExchange directExchange = new DirectExchange(EXCHANGE, true, false);
		return directExchange;
	}

	
	@Bean
	public Queue helloQueueMsg() {
		Queue queue = new Queue(QUEUE, true, false, false);
		return queue;
	}

	
	@Bean
	public Binding helloBindingQueueMsg() {
		Binding binding = BindingBuilder.bind(helloQueueMsg()).to(helloExchange()).with(RoutingKey);
		return binding;
	}

}

@Slf4j
@Component
public class DirectMsgListener {

    @Autowired
    private MsgListener msgListener;

	//指定队列名称
    @RabbitListener(queues = "fanout")
    public void displayMailFanout(JSONObject messageVo, Channel channel, Message message) throws IOException {
        //回调处理消息
        try {
            log.info("directMsg队列监听器收到消息开始：" + messageVo.toString());

            //调用发送消息接口
            msgListener.send(messageVo);

            log.info("directMsg队列监听器收到消息结束：" + messageVo.toString());
        } catch (Exception e) {
            log.info("***********************************************发送消息失败："+e.getMessage());
            e.printStackTrace();
            log.info("***********************************************发送消息失败："+e);
        } finally {
            log.info("directMsg队列监听器收到消息结束：" + messageVo.toString() + message.getMessageProperties().getDeliveryTag());
            //这段代码表示，这次消息，我已经接受并消费掉了，不会再重复发送消费
            channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
        }
    }
}
