springboot操作rabbitmq

1：新建amqp-demo工程并添加依赖

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.amqp</groupId>
            <artifactId>spring-rabbit-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

2：新建producer模块

（1）application.properties

server.port=8081

spring.rabbitmq.addresses=192.168.100.13:5672
spring.rabbitmq.connection-timeout=15000
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin

（2）RabbitMQConfig.java

@Configuration
public class RabbitMQConfig {
    public static final String MY_TOPIC_EXCHANGE = "my_topic_exchange";
    public static final String MY_QUEUE = "my_queue";

    @Bean("myTopicExchange")
    public Exchange myTopicExchange(){
        return ExchangeBuilder.topicExchange(MY_TOPIC_EXCHANGE).durable(true).build();
    }

    @Bean("myQueue")
    public Queue myQueue(){
        return QueueBuilder.durable(MY_QUEUE).build();
    }

    @Bean
    public Binding itemQueueExchange(@Qualifier("myQueue") Queue queue,
                                     @Qualifier("myTopicExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("my.#").noargs();
    }
}

（3）RabbitSender.java

@Component
public class RabbitSender {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void sendMsg(String key, Object msg){
        rabbitTemplate.convertAndSend(RabbitMQConfig.MY_TOPIC_EXCHANGE, key, msg);
    }
}

（4）SenderController.java

@RestController
@RequestMapping(
        value = "/message",
        produces = "application/json;charset=utf-8",
        headers = "Accept=application/json"
)
public class SenderController {

    @Autowired
    private RabbitSender rabbitSender;

    @PostMapping("/sender")
    public Map<String,Object> sender(@RequestBody Map<String,Object> params){
        Map<String,Object> result = new HashMap<>();
        int code = 0;
        String msg = "消息发送成功";

        rabbitSender.sendMsg("my.queue", params);

        result.put("code", code);
        result.put("msg", msg);

        return result;
    }
}

3：新建consumer模块

（1）application.properties

server.port=8083

spring.rabbitmq.addresses=192.168.100.13:5672
spring.rabbitmq.connection-timeout=15000
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin
spring.rabbitmq.listener.concurrency=10
spring.rabbitmq.listener.max-concurrency=20
spring.rabbitmq.listener.prefetch=5

（2）RabbitReceiver.java

@Component
public class RabbitReceiver {

    @RabbitListener(queuesToDeclare = @Queue("my_queue"))
    public void onMessage(Map<String,Object> msg){
        System.out.println("收到消息:"+msg);
    }
}
