多个springboot整合使用rabbitmq(使用注解的方式)

一、简述

先参考单个springboot使用rabbitmq和了解rabbitmq的五种模式

单个springboot整合rabbitmq_java-zh的博客-CSDN博客

二、创建项目

1、先创建两个springboot项目，一个做生产者，一个做消费者

 2、导包(生产者和消费者对应的内容都是一样)

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.1</version><relativePath/></parent><groupId>com.mq</groupId><artifactId>mqcloud</artifactId><version>0.0.1-SNAPSHOT</version><properties><spring-cloud-alibaba.version>2021.1</spring-cloud-alibaba.version><java.version>1.8</java.version><spring-boot.version>2.5.3</spring-boot.version><lombok.version>1.18.14</lombok.version><mybaits.plus.version>3.3.2</mybaits.plus.version><alibaba.json.version>1.2.75</alibaba.json.version><spring-cloud-starter-bootstrap.version>3.0.2</spring-cloud-starter-bootstrap.version></properties><!--    <dependencyManagement>--><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--AOP--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><!--bootstrap 启动器--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId><version>${spring-cloud-starter-bootstrap.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>${alibaba.json.version}</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>${lombok.version}</version><optional>true</optional></dependency><!--jjwt--><dependency><groupId>io.jsonwebtoken</groupId><artifactId>jjwt</artifactId><version>0.9.0</version></dependency><dependency><groupId>com.google.guava</groupId><artifactId>guava</artifactId><version>31.1-jre</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>3.12.0</version></dependency><!--zhong 基础jar--><dependency><groupId>com.common</groupId><artifactId>base</artifactId><version>1.0-SNAPSHOT</version></dependency><!--消息队列 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId><version>3.0.4</version></dependency></dependencies><!--    </dependencyManagement>--></project>

3、编写配置文件

这里的配置文件生产者和消费者都一样

spring:rabbitmq:#如果是集群，用,隔开connection-timeout: 15000username: adminpassword: 123456#虚拟host，可以不设置virtual-host: /listener:simple:acknowledge-mode: auto  #manual:手动处理 auto:自动处理#消费端监听个数(即@RabbitListenter开启几个线程去处理)concurrency: 10#消费端监听的最大个数max-concurrency: 10prefetch: 5default-requeue-rejected: true  #消费不成功的消息,拒绝入队retry:enabled: true #开启消息重试max-attempts: 4 #重试次数max-interval: 10000 #重试最大间隔时间initial-interval: 2000 #重试初始间隔时间#消息确认方式,通过correlated来确认publisher-confirm-type: correlatedpublisher-returns: truehost: 192.168.139.128port: 5672
rabbitmq:#订阅模式(扇形模式)  fanout:exchange:#交换机名称name1: exchange.fanoutqueue:#通道名称name1: exchange.fanout.queue_1name2: exchange.fanout.queue_2#交换机模式  direct:exchange:name1: exchange.directqueue:name1: exchange.direct.queue_1name2: exchange.direct.queue_2routing:name1: exchange.direct.routing.1name2: exchange.direct.routing.2#主题模式  topic:exchange: name1: exchange.topicqueue:name1: exchange.topic.queue_1name2: exchange.topic.queue_2routing:name1: '#.routingkey.#'name2: routingkey.*      

三、编码代码和测试结果

这里以rabbitmq的订阅模式(扇形模式)、路由器模式、主题模式为案例

3.1 扇形模式

生产者

@Autowired
private  RabbitTemplate rabbitTemplate;// 订阅模式的交换机名称
@Value("${rabbitmq.fanout.exchange.name1}")private String exchangeName;/*** 订阅模式(扇形模式)生产者** @param context*/
@GetMapping("/fanout/{context}")
public void sendMessage(@PathVariable String context) {System.out.println("需要发送得内容为:" + context);rabbitTemplate.convertAndSend(exchangeName, "", context);
}

消费者

注意：消费者绑定交换机和通道的值必须是固定常量值，所以我们直接从配置文件中读取

@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.fanout.exchange.name1}", type = ExchangeTypes.FANOUT),value = @Queue(value = "${rabbitmq.fanout.queue.name1}")))@RabbitHandlerpublic void consumerFanoutExchange(String context) {System.out.println("订阅模式，通道一接收到的内容为内容:" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.fanout.exchange.name1}", type = ExchangeTypes.FANOUT),value = @Queue(value = "${rabbitmq.fanout.queue.name2}")))@RabbitHandlerpublic void consumerFanoutExchange2(String context) {System.out.println("订阅模式，通道二接收到的内容为内容:" + context);
}

3.2 路由器模式

生产者

@Autowired
private  RabbitTemplate rabbitTemplate;// 路由器模式的交换机名称
@Value("${rabbitmq.direct.exchange.name1}")
private String directName;// 路由器模式的路由key1
@Value("${rabbitmq.direct.routing.name1}")
private String directRoutingKeyName1;//路由器模式的路由key2
@Value("${rabbitmq.direct.routing.name2}")
private String directRoutingKeyName2;/*** 路由器模式* @param context* @param routingkey*/
@GetMapping("/direct")
public void sendMessageDirect(@RequestParam("context") String context, @RequestParam("routingkey") Integer routingkey) {if (1 == routingkey) {rabbitTemplate.convertAndSend(directName, directRoutingKeyName1, context);} else if (2 == routingkey) {rabbitTemplate.convertAndSend(directName, directRoutingKeyName2, context);} else {System.out.println("数据非法");}
}

消费者

@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.direct.exchange.name1}", type = ExchangeTypes.DIRECT),value = @Queue(value = "${rabbitmq.direct.queue.name1}"),key = "${rabbitmq.direct.routing.name1}"))public void exchangeDirectRoutingKey1(String context, Message message) {System.out.println("key1:" + message.getMessageProperties().getReceivedRoutingKey());System.out.println("路由器模式1 接收到的消息为:" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.direct.exchange.name1}", type = ExchangeTypes.DIRECT),value = @Queue(value = "${rabbitmq.direct.queue.name2}"),key = "${rabbitmq.direct.routing.name2}"))public void exchangeDirectRoutingKey2(String context, Message message) {System.out.println("key2:" + message.getMessageProperties().getReceivedRoutingKey());System.out.println("路由器模式2 接收到的消息为" + context);}

3.3 主题模式

生产者

// 主题模式的交换机名称@Value("${rabbitmq.topic.exchange.name1}")private String topicName;//用来匹配主题模式对应的keypublic static final String EXCHANGE_TOPIC_CASE_KEY_1 = "topic.routingkey.case1";//如果case_key_2这样写,那么绑定case_key_1的队列一样会接收到，因为case_key_2也一样和key1匹配上public static final String EXCHANGE_TOPIC_CASE_KEY_2 = "routingkey.case2";@GetMapping("/topic")public void sendMessageTopic(@RequestParam("context") String context, @RequestParam("routingkey") Integer routingkey) {if (1 == routingkey) {rabbitTemplate.convertAndSend(topicName, EXCHANGE_TOPIC_CASE_KEY_1, context + routingkey);} else if (2 == routingkey) {rabbitTemplate.convertAndSend(topicName, EXCHANGE_TOPIC_CASE_KEY_2, context + routingkey);} else {System.out.println("数据非法");}}

消费者

@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.topic.exchange.name1",  type = ExchangeTypes.TOPIC),value = @Queue(value = "${rabbitmq.topic.queue.name1}"),key = "${rabbitmq.topic.routing.name1}"))@RabbitHandlerpublic void exchangeTopicRoutingKey1(String context, Message message) {System.out.println("key1:"+message.getMessageProperties().getReceivedRoutingKey());System.out.println("主题模式1:接收的内容为:"+ context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.topic.exchange.name1", type = ExchangeTypes.TOPIC),value = @Queue(value = "${rabbitmq.topic.queue.name2}"),key = "${rabbitmq.topic.routing.name2}"))@RabbitHandlerpublic void exchangeTopicRoutingKey2(String context,  Message message) {System.out.println("key2:"+message.getMessageProperties().getReceivedRoutingKey());System.out.println("主题模式2:接收的内容为:"+ context);}

3.4 全量代码

生产者

@RestController
@RequiredArgsConstructor
@RequestMapping("/test/mq")
public class ProductController {private final RabbitTemplate rabbitTemplate;// 订阅模式的交换机名称@Value("${rabbitmq.fanout.exchange.name1}")private String exchangeName;// 路由器模式的交换机名称@Value("${rabbitmq.direct.exchange.name1}")private String directName;// 路由器模式的路由key1@Value("${rabbitmq.direct.routing.name1}")private String directRoutingKeyName1;//路由器模式的路由key2@Value("${rabbitmq.direct.routing.name2}")private String directRoutingKeyName2;// 主题模式的交换机名称@Value("${rabbitmq.topic.exchange.name1}")private String topicName;//用来匹配主题模式对应的keypublic static final String EXCHANGE_TOPIC_CASE_KEY_1 = "topic.routingkey.case1";//如果case_key_2这样写,那么绑定case_key_1的队列一样会接收到，因为case_key_2也一样和key1匹配上public static final String EXCHANGE_TOPIC_CASE_KEY_2 = "routingkey.case2";/*** 订阅模式(扇形模式)生产者** @param context*/@GetMapping("/fanout/{context}")public void sendMessage(@PathVariable String context) {System.out.println("需要发送得内容为:" + context);rabbitTemplate.convertAndSend(exchangeName, "", context);}/*** 路由器模式* @param context* @param routingkey*/@GetMapping("/direct")public void sendMessageDirect(@RequestParam("context") String context, @RequestParam("routingkey") Integer routingkey) {if (1 == routingkey) {rabbitTemplate.convertAndSend(directName, directRoutingKeyName1, context);} else if (2 == routingkey) {rabbitTemplate.convertAndSend(directName, directRoutingKeyName2, context);} else {System.out.println("数据非法");}}@GetMapping("/topic")public void sendMessageTopic(@RequestParam("context") String context, @RequestParam("routingkey") Integer routingkey) {if (1 == routingkey) {rabbitTemplate.convertAndSend(topicName, EXCHANGE_TOPIC_CASE_KEY_1, context + routingkey);} else if (2 == routingkey) {rabbitTemplate.convertAndSend(topicName, EXCHANGE_TOPIC_CASE_KEY_2, context + routingkey);} else {System.out.println("数据非法");}}
}

消费者

@Component
public class ConsumerTest {@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.fanout.exchange.name1}", type = ExchangeTypes.FANOUT),value = @Queue(value = "${rabbitmq.fanout.queue.name1}")))@RabbitHandlerpublic void consumerFanoutExchange(String context) {System.out.println("订阅模式，通道一接收到的内容为内容:" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.fanout.exchange.name1}", type = ExchangeTypes.FANOUT),value = @Queue(value = "${rabbitmq.fanout.queue.name2}")))@RabbitHandlerpublic void consumerFanoutExchange2(String context) {System.out.println("订阅模式，通道二接收到的内容为内容:" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.direct.exchange.name1}", type = ExchangeTypes.DIRECT),value = @Queue(value = "${rabbitmq.direct.queue.name1}"),key = "${rabbitmq.direct.routing.name1}"))public void exchangeDirectRoutingKey1(String context, Message message) {System.out.println("key1:" + message.getMessageProperties().getReceivedRoutingKey());System.out.println("路由器模式1 接收到的消息为:" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.direct.exchange.name1}", type = ExchangeTypes.DIRECT),value = @Queue(value = "${rabbitmq.direct.queue.name2}"),key = "${rabbitmq.direct.routing.name2}"))public void exchangeDirectRoutingKey2(String context, Message message) {System.out.println("key2:" + message.getMessageProperties().getReceivedRoutingKey());System.out.println("路由器模式2 接收到的消息为" + context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.topic.exchange.name1",  type = ExchangeTypes.TOPIC),value = @Queue(value = "${rabbitmq.topic.queue.name1}"),key = "${rabbitmq.topic.routing.name1}"))@RabbitHandlerpublic void exchangeTopicRoutingKey1(String context, Message message) {System.out.println("key1:"+message.getMessageProperties().getReceivedRoutingKey());System.out.println("主题模式1:接收的内容为:"+ context);}@RabbitListener(bindings = @QueueBinding(exchange = @Exchange(value = "${rabbitmq.topic.exchange.name1", type = ExchangeTypes.TOPIC),value = @Queue(value = "${rabbitmq.topic.queue.name2}"),key = "${rabbitmq.topic.routing.name2}"))@RabbitHandlerpublic void exchangeTopicRoutingKey2(String context,  Message message) {System.out.println("key2:"+message.getMessageProperties().getReceivedRoutingKey());System.out.println("主题模式2:接收的内容为:"+ context);}}
