RabbitMQ创建交换机和队列 在RabbitMQ控制台新建交换机hmall.fanout新建两个队列fanout.queue1和fanout.queue2并将连个队列和交换机进行绑定即可。 操作如下图所示 一下操作可以通过代码实现具体参考配置类 1创建队列
2创建交换机 3绑定 2. 代码实现 1引入依赖

/dependency2配置MQ配置信息
spring:rabbitmq:host: 192.168.150.101 #主机ipport: 5672 #端口virtual-host: /hmall #虚拟主机username: hmall #用户名password: 123 #密码exchange: hmall.fanoutproducer:queue1: fanout.queue1
3声明队列和交换机配置类
Component
public class FanoutConfg{Value(${spring.rabbitmq.exchange})private String exchangeValue(${spring.rabbitmq.producer.queue1})private String queueName1// 声明fanout交换机Beanpublic FanoutExchange fanoutExchange(){return new FanoutExchange(exchanage);}// 声明队列Beanpublic Queue fanoutQueue1(){return new Queue(queueName1);}//绑定队列和交换机Beanpublic Binding bindingQueue1(Queue fanoutQueue1,FanoutExchange fanoutExchange){return BindingBuilder,build(fanoutQueue1).to(fanoutExchange);}
}4生产者
Component
public class RabbitMqProduce {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.producer.queue})private String queueName;/*** 入参说明* 第一个参数queueName队列名称* 第二个参数路由键fanout类型不需要路由键* 第三个参数msg 消息题内容*/public void send(String msg){rabbitTemplete.covertAndSend(queueName,null,msg);}}4消费者
Component
public class RabbitMqListener {RabbitListener(queues${spring.rabbitmq.producer.queue})public void counsume(String msg){System.out.pringln(消费者收到 fanout.queue队列发的消息,msg);}
}5测试类
SpringBootTest
public class SpringBootTest{AUtowiredprivate RabbitMqProduce producer;Testpublic void testSendFanoutMsg(){producer.send(fanout类型发送消息);}
}二 direct类型发送消息 控制台操作 1交换机和队列的创建参考fanout的操作 2绑定与fanout不同的是 给交换机绑定队列的同时需要指定路由键如下图所示 代码实现 1依赖引入参考fanout类型的消息 2mq消息配置
spring:rabbitmq:host: 192.168.150.101 #主机ipport: 5672 #端口virtual-host: /hmall #虚拟主机username: hmall #用户名password: 123 #密码exchange: hmall.directproducer:queue1: direct.queue1queue2: direct.queue2routingKey1: redroutingKey2: red2
3MQ配置类 以下配置可以在消费者注解上实现
Component
public class RabbitMqConfig {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.producer.exchange})private String exchange;value(${spring.rabbitmq.producer.queue1})private String queueName1;value(${spring.rabbitmq.producer.queue2})private String queueName2;value(${spring.rabbitmq.producer.routingKey1})private String routingKey1;value(${spring.rabbitmq.producer.routingKey2})private String routingKey2;// 创建交换机Bean(directExchange)public Exchange getExchange(){return ExchangeBuilder.topicExchange(exchange) // 交换机类型交换机名称.durable(true) //ture为持久化存到磁盘false存到内存.build();}// 创建队列Bean(directQueue1)public Queue getDirectQueue1(){retuen new Queue(queueName1);}// 交换机绑定队列beanpublic Binging bindDirectQueue1(Qualifier(directExchange) Exchange exchange,Qualifier(directQueue1) Queue queue){return BindingBuilder.bind(queue).to(exchange).with(routingKey1).noargs(); }// 创建队列Bean(directQueue2)public Queue getDirectQueue2(){retuen new Queue(queueName2);}// 交换机绑定队列beanpublic Binging bindDirectQueue2(Qualifier(directExchange) Exchange exchange,Qualifier(directQueue2) Queue queue){return BindingBuilder.bind(queue).to(exchange).with(routingKey2).noargs(); }}4生产者发送消息
Component
public class RabbitMqProduce {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.producer.queue1})private String queueName1;value(${spring.rabbitmq.producer.queue2})private String queueName2;value(${spring.rabbitmq.producer.routingKey2})private String routingKey1;value(${spring.rabbitmq.producer.routingKey1})private String routingKey2;/*** 入参说明* 第一个参数queueName队列名称* 第二个参数路由键fanout类型不需要路由键* 第三个参数msg 消息题内容*/public void sendQueue1(String msg){rabbitTemplete.covertAndSend(queueName1,routingKey1,msg);}public void sendQueue2(String msg){rabbitTemplete.covertAndSend(queueName2,routingKey2,msg);}}5消费者监听消息 第一种已经编写了配置类
Component
public class RabbitMqListener {RabbitListener(queues${spring.rabbitmq.producer.queue1})public void counsume(String msg){System.out.pringln(消费者收到 direct.queue1队列发的消息,msg);}RabbitListener(queues${spring.rabbitmq.producer.queue2})public void counsume(String msg){System.out.pringln(消费者收到 direct.queue2队列发的消息,msg);}
}第二种在注解上配置交换机和队列以及路由键
Component
public class RabbitMqListener {RabbitListener(bindings QueueBinding(value Queue(name${spring.rabbitmq.producer.queue1},durabletrue),exchange Exchange(name${spring.rabbitmq.producer.exchange),typeExchangeType.DIRECT),key {${spring.rabbitmq.producer.routingKey1},${spring.rabbitmq.producer.routingKey2}} ))public void counsume(String msg){System.out.pringln(消费者收到 direct.queue1队列发的消息,msg);}RabbitListener(bindings QueueBinding(value Queue(name${spring.rabbitmq.producer.queue2},durabletrue),exchange Exchange(name${spring.rabbitmq.producer.exchange),typeExchangeType.DIRECT),key {${spring.rabbitmq.producer.routingKey1},${spring.rabbitmq.producer.routingKey2}} ))public void counsume(String msg){System.out.pringln(消费者收到 direct.queue2队列发的消息,msg);}
}6测试类
SpringBootTest
public class SpringBootTest{AUtowiredprivate RabbitMqProduce producer;Testpublic void testSendDirectMsg(){producer.send(direct类型发送消息);}
}三 Topic类型消息 控制台操作 参考前面的创建交换机队列以及绑定关系操作代码实现 1依赖引入参考fanout类型的消息 2mq消息配置 路由键使用通配符进行匹配,#代表多个*代表一个
spring:rabbitmq:host: 192.168.150.101 #主机ipport: 5672 #端口virtual-host: /hmall #虚拟主机username: hmall #用户名password: 123 #密码exchange: hmall.topicproducer:queue1: topic.queue1queue2: topic.queue2routingKey1: china.#routingKey2: #.news
3MQ配置类
Component
public class RabbitMqConfig {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.producer.exchange})private String exchange;value(${spring.rabbitmq.producer.queue1})private String queueName1;value(${spring.rabbitmq.producer.queue2})private String queueName2;value(${spring.rabbitmq.producer.routingKey1})private String routingKey1;value(${spring.rabbitmq.producer.routingKey2})private String routingKey2;// 创建交换机Bean(topicExchange)public Exchange getExchange(){return ExchangeBuilder.topicExchange(exchange) // 交换机类型交换机名称.durable(true) //ture为持久化存到磁盘false存到内存.build();}// 创建队列Bean(topicQueue1)public Queue getDirectQueue1(){retuen new Queue(queueName1);}// 交换机绑定队列beanpublic Binging bindDirectQueue1(Qualifier(topicExchange) Exchange exchange,Qualifier(topicQueue1) Queue queue){return BindingBuilder.bind(queue).to(exchange).with(routingKey1).noargs(); }// 创建队列Bean(topicQueue2)public Queue getDirectQueue2(){retuen new Queue(queueName2);}// 交换机绑定队列beanpublic Binging bindDirectQueue2(Qualifier(topicExchange) Exchange exchange,Qualifier(topicQueue2) Queue queue){return BindingBuilder.bind(queue).to(exchange).with(routingKey2).noargs(); }}4生产者发送消息
Component
public class RabbitMqProduce {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.producer.queue1})private String queueName1;value(${spring.rabbitmq.producer.queue2})private String queueName2;value(${spring.rabbitmq.producer.routingKey2})private String routingKey1;value(${spring.rabbitmq.producer.routingKey1})private String routingKey2;/*** 入参说明* 第一个参数queueName队列名称* 第二个参数路由键fanout类型不需要路由键* 第三个参数msg 消息题内容*/public void sendQueue1(String msg){rabbitTemplete.covertAndSend(queueName1,routingKey1,msg);}public void sendQueue2(String msg){rabbitTemplete.covertAndSend(queueName2,routingKey2,msg);}}5消费者监听消息
Component
public class RabbitMqListener {RabbitListener(queues${spring.rabbitmq.producer.queue1})public void counsume(String msg){System.out.pringln(消费者收到 topic.queue1队列发的消息,msg);}RabbitListener(queues${spring.rabbitmq.producer.queue2})public void counsume(String msg){System.out.pringln(消费者收到 topic.queue2队列发的消息,msg);}
}6测试类
SpringBootTest
public class SpringBootTest{AUtowiredprivate RabbitMqProduce producer;Testpublic void testSendDirectMsg(){producer.send(direct类型发送消息);}
}四 消息转换器
MQ会把消息体变成字节码 解决办法使用消息转换器实现如下
在生产者和消费者两个服务引入依赖
dependencygroupIdcom.fasterxml.jackson/groupIdartifactIdjasckson-databind/artifactId
/dependency在生产者和消费者两个服务编写消息转换器配置
Component
public class JacksonMessageConvertor{Beanpublic MessageCoverter jacksonMessageConvertor(){return new Jackson2JsonMessageConverter();}
}消息体 对于生产者来说是map类型的则生成者接收的时候也是map类型 例如
Component
public class RabbitMqListener {RabbitListener(queues${spring.rabbitmq.producer.queue1})public void counsume(MapString,Objecct msg){System.out.pringln(消费者收到 topic.queue1队列发的消息,msg);}}五 案例演示
支付服务支付成功后通知交易服务进行后续操作 生产者和消费者两个服务都需要进行1,23步骤
添加依赖
!--mq依赖--
dependencygroupIdorg.springframework.book/groupIdartifactIdspring-boot-starter-amqp/artifactId
/dependency
!--消息转换器依赖--

消息转换器配置类
Component
public class JacksonMessageConvertor{Beanpublic MessageCoverter jacksonMessageConvertor(){return new Jackson2JsonMessageConverter();}
}生产者 1生产者的配置
Component
public class Rabbitroducer {Autowiredprivate RabbitTemplate rabbitTemplete;value(${spring.rabbitmq.queue})private String queueName;value(${spring.rabbitmq.routingKey})private String routingKey;/*** 入参说明* 第一个参数queueName队列名称* 第二个参数路由键fanout类型不需要路由键* 第三个参数msg 消息题内容*/public void sendMsg(String msg){// 发送消息rabbitTemplete.covertAndSend(queueName,routingKey, msg);}
}2业务代码支付成功发送消息
public class payOrderServiceImpl impletement PayOrderService{Autowridprivate RabbitProducer payProducer;OveriridTransactional(rollback Exception.class)public void payOrder(PayOrderDto payOrder){// 一些列操作最终交易成功// 发送消息通知try{payProducer.send(payOrder.getId());}catch(AmqpException e){log.error(交易成功发送消息异常{},e.getMessages(););}}
}消费者
Component
public class PaySatusListener {Autowiredprivate OrderService orderService;RabbitListener(bindings QueueBinding(value Queue(name${spring.rabbitmq.queue},durabletrue),exchange Exchange(name${spring.rabbitmq.exchange),typeExchangeType.TOPIC),key {${spring.rabbitmq.routingKey}} ))public void listenOrderPay(Long orderId){//标记订单为已支付orderService.markOrderPaySuccess(orderId);}}
