本文主要介紹了SpringBoot整合RabbitMQ的5種模式實戰(zhàn)，文中通過示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

一、環(huán)境準(zhǔn)備

在這里插入圖片描述

1、pom依賴

<!-- 父工程依賴 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.6.RELEASE</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.6.0</version>
        </dependency>
    </dependencies>

2、配置文件

server:
  port: 8080

spring:
  rabbitmq:
    host: 192.168.131.171
    port: 5672
    username: jihu
    password: jihu
    virtual-host: /jihu

3、啟動類

@SpringBootApplication
public class RabbitMQApplication {
   public static void main(String[] args) {
       SpringApplication.run(RabbitMQApplication.class);
   }
}

5、Swagger2類

@Configuration
@EnableSwagger2
public class Swagger2 {
    // http://127.0.0.1:8080/swagger-ui.html
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.jihu"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("極狐-Spring Boot中使用spring-boot-starter-amqp集成rabbitmq")
                .description("測試SpringBoot整合進(jìn)行各種工作模式信息的發(fā)送")
/*
	                .termsOfServiceUrl("https://www.jianshu.com/p/c79f6a14f6c9")
*/
                .contact("roykingw")
                .version("1.0")
                .build();
    }
}

6、ProducerController

@RestController
public class ProducerController {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    //helloWorld 直連模式
    @ApiOperation(value = "helloWorld發(fā)送接口", notes = "直接發(fā)送到隊列")
    @GetMapping(value = "/helloWorldSend")
    public Object helloWorldSend(String message) throws AmqpException, UnsupportedEncodingException {
        //設(shè)置部分請求參數(shù)
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);

        //發(fā)消息
        rabbitTemplate.send("helloWorldqueue", new Message(message.getBytes("UTF-8"), messageProperties));
        return "message sended : " + message;
    }


    //工作隊列模式
    @ApiOperation(value = "workqueue發(fā)送接口", notes = "發(fā)送到所有監(jiān)聽該隊列的消費")
    @GetMapping(value = "/workqueueSend")
    public Object workqueueSend(String message) throws AmqpException, UnsupportedEncodingException {
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
        //制造多個消息進(jìn)行發(fā)送操作
        for (int i = 0; i < 10; i++) {
            rabbitTemplate.send("work_sb_mq_q", new Message(message.getBytes("UTF-8"), messageProperties));
        }
        return "message sended : " + message;
    }


    // pub/sub 發(fā)布訂閱模式   交換機(jī)類型 fanout
    @ApiOperation(value = "fanout發(fā)送接口", notes = "發(fā)送到fanoutExchange。消息將往該exchange下的所有queue轉(zhuǎn)發(fā)")
    @GetMapping(value = "/fanoutSend")
    public Object fanoutSend(String message) throws AmqpException, UnsupportedEncodingException {
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
        //fanout模式只往exchange里發(fā)送消息。分發(fā)到exchange下的所有queue
        rabbitTemplate.send("fanoutExchange", "", new Message(message.getBytes("UTF-8"), messageProperties));
        return "message sended : " + message;
    }


    //routing路由工作模式  交換機(jī)類型 direct
    @ApiOperation(value = "direct發(fā)送接口", notes = "發(fā)送到directExchange。exchange轉(zhuǎn)發(fā)消息時，會往routingKey匹配的queue發(fā)送")
    @GetMapping(value = "/directSend")
    public Object routingSend(String routingKey, String message) throws AmqpException, UnsupportedEncodingException {

        if (null == routingKey) {
            routingKey = "china.changsha";
        }
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
        //fanout模式只往exchange里發(fā)送消息。分發(fā)到exchange下的所有queue
        rabbitTemplate.send("directExchange", routingKey, new Message(message.getBytes("UTF-8"), messageProperties));
        return "message sended : routingKey >" + routingKey + ";message > " + message;
    }


    //topic 工作模式   交換機(jī)類型 topic
    @ApiOperation(value = "topic發(fā)送接口", notes = "發(fā)送到topicExchange。exchange轉(zhuǎn)發(fā)消息時，會往routingKey匹配的queue發(fā)送，*代表一個單詞，#代表0個或多個單詞。")
    @GetMapping(value = "/topicSend")
    public Object topicSend(String routingKey, String message) throws AmqpException, UnsupportedEncodingException {

        if (null == routingKey) {
            routingKey = "changsha.kf";
        }
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
        //fanout模式只往exchange里發(fā)送消息。分發(fā)到exchange下的所有queue
        rabbitTemplate.send("topicExchange", routingKey, new Message(message.getBytes("UTF-8"), messageProperties));
        return "message sended : routingKey >" + routingKey + ";message > " + message;
    }

}

7、ConcumerReceiver

@Component
public class ConcumerReceiver {


    //直連模式的多個消費者，會分到其中一個消費者進(jìn)行消費。類似task模式
    //通過注入RabbitContainerFactory對象，來設(shè)置一些屬性，相當(dāng)于task里的channel.basicQos
    @RabbitListener(queues = "helloWorldqueue")
    public void helloWorldReceive(String message) {

        System.out.println("helloWorld模式 received message : " + message);
    }

    //工作隊列模式
    @RabbitListener(queues = "work_sb_mq_q")
    public void wordQueueReceiveq1(String message) {

        System.out.println("工作隊列模式1 received message : " + message);
    }

    @RabbitListener(queues = "work_sb_mq_q")
    public void wordQueueReceiveq2(String message) {

        System.out.println("工作隊列模式2 received message : " + message);
    }


    //pub/sub模式進(jìn)行消息監(jiān)聽
    @RabbitListener(queues = "fanout.q1")
    public void fanoutReceiveq1(String message) {

        System.out.println("發(fā)布訂閱模式1received message : " + message);
    }

    @RabbitListener(queues = "fanout.q2")
    public void fanoutReceiveq2(String message) {

        System.out.println("發(fā)布訂閱模式2 received message : " + message);
    }


    //Routing路由模式
    @RabbitListener(queues = "direct_sb_mq_q1")
    public void routingReceiveq1(String message) {

        System.out.println("Routing路由模式routingReceiveq11111 received message : " + message);
    }

    @RabbitListener(queues = "direct_sb_mq_q2")
    public void routingReceiveq2(String message) {

        System.out.println("Routing路由模式routingReceiveq22222 received message : " + message);
    }


    //topic 模式
    //注意這個模式會有優(yōu)先匹配原則。例如發(fā)送routingKey=hunan.IT,那匹配到hunan.*(hunan.IT,hunan.eco),之后就不會再去匹配*.ITd
    @RabbitListener(queues = "topic_sb_mq_q1")
    public void topicReceiveq1(String message) {
        System.out.println("Topic模式 topic_sb_mq_q1 received message : " + message);
    }

    @RabbitListener(queues = "topic_sb_mq_q2")
    public void topicReceiveq2(String message) {
        System.out.println("Topic模式 topic_sb_mq_q2 received  message : " + message);
    }

}

二、簡單模式

隊列配置：

/**
 * HelloWorld rabbitmq第一個工作模式
 * 直連模式只需要聲明隊列，所有消息都通過隊列轉(zhuǎn)發(fā)。
 * 無需設(shè)置交換機(jī)
 */
@Configuration
public class HelloWorldConfig {

	@Bean
	public Queue setQueue() {
		return new Queue("helloWorldqueue");
	}
}

三、工作隊列模式

@Configuration
public class WorkConfig {

    //聲明隊列
    @Bean
    public Queue workQ1() {
        return new Queue("work_sb_mq_q");
    }
}

四、廣播模式（Fanout）

/**
 * Fanout模式需要聲明exchange，并綁定queue，由exchange負(fù)責(zé)轉(zhuǎn)發(fā)到queue上。
 * 廣播模式 交換機(jī)類型設(shè)置為：fanout
 */
@Configuration
public class FanoutConfig {

	//聲明隊列
	@Bean
	public Queue fanoutQ1() {
		return new Queue("fanout.q1");
	}
	@Bean
	public Queue fanoutQ2() {
		return new Queue("fanout.q2");
	}


	//聲明exchange
	@Bean
	public FanoutExchange setFanoutExchange() {
		return new FanoutExchange("fanoutExchange");
	}


	//聲明Binding,exchange與queue的綁定關(guān)系
	@Bean
	public Binding bindQ1() {
		return BindingBuilder.bind(fanoutQ1()).to(setFanoutExchange());
	}
	@Bean
	public Binding bindQ2() {
		return BindingBuilder.bind(fanoutQ2()).to(setFanoutExchange());
	}
}

五、直連模式（Direct）

/*
   路由模式|Routing模式   交換機(jī)類型：direct
*/
@Configuration
public class DirectConfig {

	//聲明隊列
	@Bean
	public Queue directQ1() {
		return new Queue("direct_sb_mq_q1");
	}
	@Bean
	public Queue directQ2() {
		return new Queue("direct_sb_mq_q2");
	}


	//聲明exchange
	@Bean
	public DirectExchange setDirectExchange() {
		return new DirectExchange("directExchange");
	}

	//聲明binding，需要聲明一個routingKey
	@Bean
	public Binding bindDirectBind1() {
		return BindingBuilder.bind(directQ1()).to(setDirectExchange()).with("china.changsha");
	}
	@Bean
	public Binding bindDirectBind2() {
			return BindingBuilder.bind(directQ2()).to(setDirectExchange()).with("china.beijing");
	}

}

六、通配符模式（Topic）

/*
Topics模式  交換機(jī)類型 topic
* */
@Configuration
public class TopicConfig {

	//聲明隊列
	@Bean
	public Queue topicQ1() {
		return new Queue("topic_sb_mq_q1");
	}
	@Bean
	public Queue topicQ2() {
		return new Queue("topic_sb_mq_q2");
	}


	//聲明exchange
	@Bean
	public TopicExchange setTopicExchange() {
		return new TopicExchange("topicExchange");
	}

	//聲明binding，需要聲明一個roytingKey
	@Bean
	public Binding bindTopicHebei1() {
		return BindingBuilder.bind(topicQ1()).to(setTopicExchange()).with("changsha.*");
	}
	@Bean
	public Binding bindTopicHebei2() {
		return BindingBuilder.bind(topicQ2()).to(setTopicExchange()).with("#.beijing");
	}
}

測試

我們啟動上面的SpringBoot項目。

然后我們訪問swagger地址：http://127.0.0.1:8080/swagger-ui.html
