1. pom.xml 配置

<!-- RabbitMQ -->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2. 配置文件

spring:
  rabbitmq:
    first:
      host: 101.22.08.161
      port: 5672
      username: dhcs
      password: dhcs
      virtualhost: /
    second:
      host: 101.32.80.138
      port: 5672
      username: admin
      password: admin
      virtualhost: /account

3. 编写配置类

package com.example.mybatis.config.mq;

import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.amqp.SimpleRabbitListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

@Configuration
public class RabbitMQConfig {

    // ============================================ 定义连接connectionFactory ====================================================================
    @Bean(name = "mainConnectionFactory")
    @Primary
    public ConnectionFactory mainConnectionFactory(
            @Value("${spring.rabbitmq.first.host}") String host,
            @Value("${spring.rabbitmq.first.port}") int port,
            @Value("${spring.rabbitmq.first.username}") String username,
            @Value("${spring.rabbitmq.first.password}") String password,
            @Value("${spring.rabbitmq.first.virtualhost}") String virtualhost) {
        return connectionFactory(host, port, username, password, virtualhost);
    }

    @Bean(name = "secondConnectionFactory")
    public ConnectionFactory secondConnectionFactory(
            @Value("${spring.rabbitmq.second.host}") String host,
            @Value("${spring.rabbitmq.second.port}") int port,
            @Value("${spring.rabbitmq.second.username}") String username,
            @Value("${spring.rabbitmq.second.password}") String password,
            @Value("${spring.rabbitmq.second.virtualhost}") String virtualhost) {
        return connectionFactory(host, port, username, password, virtualhost);
    }


    public CachingConnectionFactory connectionFactory(String host, int port, String username, String password, String virtualhost) {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setHost(host);
        connectionFactory.setPort(port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setVirtualHost(virtualhost);
        return connectionFactory;
    }

    // ============================================ 定义RabbitTemplate ====================================================================
    @Bean(name = "mainRabbitTemplate")
    @Primary
    public RabbitTemplate mainRabbitTemplate(@Qualifier("mainConnectionFactory") ConnectionFactory connectionFactory) {
        RabbitTemplate mainRabbitTemplate = new RabbitTemplate(connectionFactory);
        mainRabbitTemplate.setMessageConverter(new Jackson2JsonMessageConverter());
        return mainRabbitTemplate;
    }

    @Bean(name = "secondRabbitTemplate")
    public RabbitTemplate secondRabbitTemplate(@Qualifier("secondConnectionFactory") ConnectionFactory connectionFactory) {
        RabbitTemplate secondRabbitTemplate = new RabbitTemplate(connectionFactory);
        secondRabbitTemplate.setMessageConverter(new Jackson2JsonMessageConverter());
        return secondRabbitTemplate;
    }


    // ============================================ 定义监听Listener ====================================================================
    @Bean(name = "mainFactory")
    @Primary
    public SimpleRabbitListenerContainerFactory mainFactory(
            SimpleRabbitListenerContainerFactoryConfigurer configurer,
            @Qualifier("mainConnectionFactory") ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setMessageConverter(new Jackson2JsonMessageConverter());
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean(name = "secondFactory")
    public SimpleRabbitListenerContainerFactory secondFactory(
            SimpleRabbitListenerContainerFactoryConfigurer configurer,
            @Qualifier("secondConnectionFactory") ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setMessageConverter(new Jackson2JsonMessageConverter());
        factory.setConcurrentConsumers(10);
        factory.setMaxConcurrentConsumers(20);
        factory.setPrefetchCount(1);
        configurer.configure(factory, connectionFactory);
        return factory;
    }
}

4. 发送消息

package com.example.mybatis.config.mq;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageBuilder;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

@Component
@Slf4j
public class Sender1 {

    @Resource(name = "mainRabbitTemplate")
    protected RabbitTemplate rabbitTemplate;

    public void test() {
        this.sendMessage("dhcs-exchange", "DHCS2KF1", "1111111111");
    }

    /**
     * @param exchange   交换机
     * @param routingKey 路由
     * @param message    消息内容
     * @return boolean
     * @Description 发送消息
     */
    private boolean sendMessage(String exchange, String routingKey, String message) {
        long start = System.currentTimeMillis();
        try {
            Message messageObj = MessageBuilder.withBody(message.getBytes())
                    .setContentType(MessageProperties.CONTENT_TYPE_JSON)
                    .build();
            rabbitTemplate.convertAndSend(exchange, routingKey, messageObj);
        } catch (Exception e) {
            log.error("【mq发送失败】", e);
            return false;
        } finally {
            long end = System.currentTimeMillis();
            log.info("【mq发送】入参:{},耗时:{}ms", message, (end - start));
        }
        return true;
    }
}


package com.example.mybatis.config.mq;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageBuilder;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

@Component
@Slf4j
public class Sender2 {

    @Resource(name = "secondRabbitTemplate")
    protected RabbitTemplate rabbitTemplate;

    public void test() {
        this.sendMessage("ssoAccount_exchange", "", "123456789");
    }

    /**
     * @param exchange   交换机
     * @param routingKey 路由
     * @param message    消息内容
     * @return boolean
     * @Description 发送消息
     */
    private boolean sendMessage(String exchange, String routingKey, String message) {
        long start = System.currentTimeMillis();
        try {
            Message messageObj = MessageBuilder.withBody(message.getBytes())
                    .setContentType(MessageProperties.CONTENT_TYPE_JSON)
                    .build();
            rabbitTemplate.convertAndSend(exchange, routingKey, messageObj);
        } catch (Exception e) {
            log.error("【mq发送失败】", e);
            return false;
        } finally {
            long end = System.currentTimeMillis();
            log.info("【mq发送】入参:{},耗时:{}ms", message, (end - start));
        }
        return true;
    }
}

5. 接收消息

package com.example.mybatis.config.mq;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@Slf4j
public class Listener1 {

    @RabbitListener(queuesToDeclare = @Queue("DHCS2KF1"), containerFactory = "mainFactory")
    @RabbitHandler
    public void process(String message) {
        log.info("Listener1 接收消息:{} ", message);
        try {
            // 逻辑处理
            System.out.println("Listener1确认消费完成 ..............................");
        } catch (Exception e) {
            log.error("Listener1确认消费异常", e);
        } finally {
            log.error("Listener1确认消费：{}", message);
        }
    }
}

package com.example.mybatis.config.mq;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@Slf4j
public class Listener2 {

    @RabbitListener(queuesToDeclare = @Queue("sso.account.chewu.queue"), containerFactory = "secondFactory")
    @RabbitHandler
    public void process(String message) {
        log.info("Listener2 接收消息:{} ", message);
        try {
            // 逻辑处理
            System.out.println("Listener2确认消费完成 ..............................");
        } catch (Exception e) {
            log.error("Listener2确认消费异常", e);
        } finally {
            log.error("Listener2确认消费：{}", message);
        }
    }
}
