简介
MQ 是开发中很平常的中间件，本文讲述的是怎么在一个 Spring Boot 项目中配置多源的 RabbitMQ，这里不过多的讲解RabbitMQ 的相关知识点。如果你也有遇到需要往多个 RabbitMQ 中发送消息的需求，希望本文可以帮助到你。
环境
- rabbitmq 3.7.12
- spring boot 2.1.6.RELEASE
当然软件的版本不是硬性要求，只是我使用的环境而已，唯一的要求是需要启动两个 RabbitMQ，我这边是在kubernetes 集群中使用 helm 官方提供的 charts 包快速启动的两个 rabbitmq-ha 高可用 rabbitmq 集群。
想要了解 kubernetes或者helm, 可以参看以下 github 仓库：
- kubernetes : https://github.com/kubernetes…
- helm: https://github.com/helm/helm
- charts: https://github.com/helm/charts
SpringBoot 中配置两个 RabbitMQ 源
在 springboot 中配置单个 RabbitMQ 是极其简单的，我们只需要使用 Springboot 为我们自动装配的 RabbitMQ 相关的配置就可以了。但是需要配置多个源时，第二个及其以上的就需要单独配置了，这里我使用的都是单独配置的。
代码：
/**
* @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;
}
}第一个源的配置代码
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);
}
}第二个源的配置代码
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);
}
}配置信息
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测试
这样我们的两个 RabbitMQ 源就配置好了，接下来我们进行测试使用，为了方便使用，我写了一个 MultiRabbitTemplate.class 方便我们使用不同的源。
/**
* @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;
}第一个消息发送者类 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");
}
}第二个消息发送者类 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");
}
}动态创建 Queue 的消费者
/**
* @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);
}
}测试类
@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
public class SpringBootMultiRabbitmqApplicationTests extends MultiRabbitTemplate {
@Autowired
private TestFirstSender firstSender;
@Autowired
private TestSecondSender secondSender;
/**
* 一百个线程向 First Rabbitmq 的 rabbitmq1 queue 中发送一百条消息
*/
@Test
public void testFirstSender() {for (int i = 0; i < 100; i++) {new Thread(() ->
firstSender.rabbitmq1sender()).start();}
try {Thread.sleep(1000 * 10);
} catch (InterruptedException e) {e.printStackTrace();
}
}
/**
* 一百个线程向 Second Rabbitmq 的 rabbitmq2 queue 中发送一百条消息
*/
@Test
public void testSecondSender() {for (int i = 0; i < 100; i++) {new Thread(() ->
secondSender.rabbitmq2sender()).start();}
try {Thread.sleep(1000 * 10);
} catch (InterruptedException e) {e.printStackTrace();
}
}
}测试结果：
总结
这样配置好之后我们就可向两个 RabbitMQ 中发送消息啦。这里只配置了两个源，当然如果你需要更多的源，仅仅只需要配置 *RabbitConfiguration.class 就可以啦。本文没有多说关于 RabbitMQ 的相关知识，如果未使用过需要自己了解一下相关知识。
