您好,登录后才能下订单哦!
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。
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:
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。

@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
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:
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。
