Spring Boot configures multi-source RabbitMQ

Posted by menriquez on Fri, 19 Jul 2019 09:01:44 +0200

brief introduction

MQ is a common middleware in development. This article describes how to configure multi-source RabbitMQ in a Spring Book project. There are not many knowledge points about RabbitMQ here. If you also have a need to send messages to multiple RabbitMQ, I hope this article can help you.

Environmental Science

  • rabbitmq 3.7.12
  • spring boot 2.1.6.RELEASE

Of course, the software version is not a hard requirement, but the environment I use. The only requirement is to start two RabbitMQ clusters. Here, I use two rabbitmq-ha high-availability rabbitmq clusters which are quickly started by the charts package provided by helm in the kubernetes cluster.

To learn about kubernetes or helm, see the following github repositories:

  • kubernetes : <https: github.com kubernetes>
  • helm: <https: github.com helm>
  • charts: <https: github.com helm charts>

Configure two RabbitMQ sources in SpringBook

Configuring a single RabbitMQ in Springboot is extremely simple. We just need to use Springboot to configure the RabbitMQ-related configuration for our automatic assembly. But when you need to configure multiple sources, the second and more need to be configurated separately. Here I use a separate configuration.

Code:
/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@Data
public abstract class AbstractRabbitConfiguration {

    protected String host;
    protected int port;
    protected String username;
    protected String password;

    protected ConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setHost(host);
        connectionFactory.setPort(port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        return connectionFactory;
    }
}

Configuration code for the first source

package com.zhw.study.springbootmultirabbitmq.config;

import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.amqp.SimpleRabbitListenerContainerFactoryConfigurer;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

/**
 * @author innerpeacez
 * @since 2019/3/8
 */

@Configuration
@ConfigurationProperties("spring.rabbitmq.first")
public class FirstRabbitConfiguration extends AbstractRabbitConfiguration {

    @Bean(name = "firstConnectionFactory")
    @Primary
    public ConnectionFactory firstConnectionFactory() {
        return super.connectionFactory();
    }

    @Bean(name = "firstRabbitTemplate")
    @Primary
    public RabbitTemplate firstRabbitTemplate(@Qualifier("firstConnectionFactory") ConnectionFactory connectionFactory) {
        return new RabbitTemplate(connectionFactory);
    }

    @Bean(name = "firstFactory")
    public SimpleRabbitListenerContainerFactory firstFactory(SimpleRabbitListenerContainerFactoryConfigurer configurer,
                                                             @Qualifier("firstConnectionFactory") ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean(value = "firstRabbitAdmin")
    public RabbitAdmin firstRabbitAdmin(@Qualifier("firstConnectionFactory") ConnectionFactory connectionFactory) {
        return new RabbitAdmin(connectionFactory);
    }
}

Configuration code for the second source

package com.zhw.study.springbootmultirabbitmq.config;

import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.amqp.SimpleRabbitListenerContainerFactoryConfigurer;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author innerpeacez
 * @since 2019/3/8
 */

@Configuration
@ConfigurationProperties("spring.rabbitmq.second")
public class SecondRabbitConfiguration extends AbstractRabbitConfiguration {

    @Bean(name = "secondConnectionFactory")
    public ConnectionFactory secondConnectionFactory() {
        return super.connectionFactory();
    }

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

    @Bean(name = "secondFactory")
    public SimpleRabbitListenerContainerFactory secondFactory(SimpleRabbitListenerContainerFactoryConfigurer configurer,
                                                             @Qualifier("secondConnectionFactory") ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean(value = "secondRabbitAdmin")
    public RabbitAdmin secondRabbitAdmin(@Qualifier("secondConnectionFactory") ConnectionFactory connectionFactory) {
        return new RabbitAdmin(connectionFactory);
    }
}

configuration information

spring:
  application:
    name: multi-rabbitmq
  rabbitmq:
    first:
      host: 192.168.10.76
      port: 30509
      username: admin
      password: 123456
    second:
      host: 192.168.10.76
      port: 31938
      username: admin
      password: 123456
test

So our two RabbitMQ sources are configured. Next, we test and use them. For ease of use, I wrote a MultiRabbitTemplate.class to facilitate our use of different sources.

/**
 * @author innerpeacez
 * @since 2019/3/8
 */
@Component
public abstract class MultiRabbitTemplate {

    @Autowired
    @Qualifier(value = "firstRabbitTemplate")
    public AmqpTemplate firstRabbitTemplate;

    @Autowired
    @Qualifier(value = "secondRabbitTemplate")
    public AmqpTemplate secondRabbitTemplate;
}

The first message sender class, TestFirstSender.class

/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@Component
@Slf4j
public class TestFirstSender extends MultiRabbitTemplate implements MessageSender {

    @Override
    public void send(Object msg) {
        log.info("rabbitmq1 , msg: {}", msg);
        firstRabbitTemplate.convertAndSend("rabbitmq1", msg);
    }

    public void rabbitmq1sender() {
        this.send("innerpeacez1");
    }
}

The second message sender class TestSecondSender.class

/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@Component
@Slf4j
public class TestSecondSender extends MultiRabbitTemplate implements MessageSender {

    @Override
    public void send(Object msg) {
        log.info("rabbitmq2 , msg: {}", msg);
        secondRabbitTemplate.convertAndSend("rabbitmq2", msg);
    }

    public void rabbitmq2sender() {
        this.send("innerpeacez2");
    }
}

Consumers creating Queue dynamically

/**
 * @author innerpeacez
 * @since 2019/3/11
 */

@Slf4j
@Component
public class TestFirstConsumer implements MessageConsumer {

    @Override
    @RabbitListener(bindings = @QueueBinding(value = @Queue("rabbitmq1")
            , exchange = @Exchange("rabbitmq1")
            , key = "rabbitmq1")
            , containerFactory = "firstFactory")
    public void receive(Object obj) {
        log.info("rabbitmq1 , {}", obj);
    }

}

/**
 * @author innerpeacez
 * @since 2019/3/11
 */

@Slf4j
@Component
public class TestSecondConsumer implements MessageConsumer {

    @Override
    @RabbitListener(bindings = @QueueBinding(value = @Queue("rabbitmq2")
            , exchange = @Exchange("rabbitmq2")
            , key = "rabbitmq2")
            , containerFactory = "secondFactory")
    public void receive(Object obj) {
        log.info("rabbitmq2 , {}", obj);
    }

}

Test class

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
public class SpringBootMultiRabbitmqApplicationTests extends MultiRabbitTemplate {

    @Autowired
    private TestFirstSender firstSender;
    @Autowired
    private TestSecondSender secondSender;

    /**
     * One hundred threads send one hundred messages to rabbitmq1 queue of First Rabbitmq
     */
    @Test
    public void testFirstSender() {
        for (int i = 0; i &lt; 100; i++) {
            new Thread(() -&gt;
                    firstSender.rabbitmq1sender()
            ).start();
        }
        try {
            Thread.sleep(1000 * 10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    /**
     * One hundred threads send one hundred messages to rabbitmq2 queue of Second Rabbitmq
     */
    @Test
    public void testSecondSender() {
        for (int i = 0; i &lt; 100; i++) {
            new Thread(() -&gt;
                    secondSender.rabbitmq2sender()
            ).start();
        }
        try {
            Thread.sleep(1000 * 10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }
}

Test results:

summary

With this configuration, we can send messages to two RabbitMQ. There are only two sources configured here, of course, if you need more, just configure * RabbitConfiguration.class. This article does not say much about RabbitMQ, if you have not used it, you need to know about it yourself.
