RabbitMQ使用——基于SpringBoot

一、简单示例：

　　1）创建一个spring boot项目：

　　

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

　　2）配置application.yml

spring:
  application:
    name: spring-boot-amqp
  rabbitmq:
    host: 192.168.80.140
    port: 5672
    username: rabbit
    password: 123456

　　3）创建列队配置：

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMQConfiguration {
    @Bean
    public Queue queue() {
        return new Queue("helloRabbit");
    }
}

　　4）消费者：

@Component
public class HelloRabbitConsumer {
    @RabbitListener(queues = "helloRabbit")
    public void process(String message) {
        System.out.println("Consumer: " + message);
    }
}

　　5）生产者：

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

    public void send(String message) {
        rabbitTemplate.convertAndSend("helloRabbit", message);
    }
}

　　6）测试：

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitmqSpringbootApplicationTests {
    @Autowired
    private HelloRabbitProvider helloRabbitProvider;

    @Test
    public void testSender() {
        for (int i = 0; i < 10; i++) {
            helloRabbitProvider.send("hello motor");
        }
    }
}

二、路由模式：

　　1）路由/列队配置：

@Configuration
public class RabbitMQConfiguration {
    @Bean
    public Queue getQueue() {
        return new Queue("simple_queue");
    }

    @Bean
    public FanoutExchange getFanoutExchange(){
        return  new FanoutExchange("fanout_exchange_new");
    }

    @Bean
    public Binding getBinding(Queue getQueue, FanoutExchange getFanoutExchange){
        return BindingBuilder.bind(getQueue).to(getFanoutExchange);
    }
}

　　2）生产者：

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

    public void send(String message) {
        //rabbitTemplate.convertAndSend("helloRabbit", message);
        rabbitTemplate.convertAndSend("fanout_exchange_new","", message);
    }
}

　　3）消费者：

@Component
public class RabbitConsumer {
    @RabbitListener(queues = "simple_queue")
    public void process(String message) {
        System.out.println("Consumer: " + message);
    }
}

　　4）测试：

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitmqSpringbootApplicationTests {
    @Autowired
    private RabbitProvider RabbitProvider;

    @Test
    public void testSender() {
        for (int i = 0; i < 10; i++) {
            RabbitProvider.send("hello motor");
        }
    }
}

三、通配符模式：

　　1）路由/列队配置：

@Configuration
public class RabbitMQConfiguration {
    @Bean
    public Queue getQueue() {
        return new Queue("simple_queue");
    }

    @Bean
    public FanoutExchange getFanoutExchange(){
        return  new FanoutExchange("fanout_exchange_new");
    }

    @Bean
    public Binding getBinding(Queue getQueue, FanoutExchange getFanoutExchange){
        return BindingBuilder.bind(getQueue).to(getFanoutExchange);
    }

    @Bean
    public TopicExchange getTopicExchange(){
        return new TopicExchange("topic_exchange_new");
    }

    @Bean
    public Binding getBinding2(Queue getQueue,TopicExchange getTopicExchange){
        return BindingBuilder.bind(getQueue).to(getTopicExchange).with("product.*");
    }
}

　　2）生产者：

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

    public void send(String message) {
        //rabbitTemplate.convertAndSend("helloRabbit", message);
        //rabbitTemplate.convertAndSend("fanout_exchange_new","", message);
        rabbitTemplate.convertAndSend("topic_exchange_new","product.add","topic模式消息");
    }
}
