【RabbitMQ】07 SpringBoot整合RabbitMQ

生产者和消费者的依赖基本一致：

注意工程名称不是一样的

配置信息也是一致的rabbitmq.properties：

# rabbitmq 信息
spring:
  rabbitmq:
    host: 192.168.2.121
    port: 5672
    username: test
    password: 123456
    virtual-host: /dzz

编写SpringBoot生产者服务：

启动类：

package cn.dzz;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Producer {

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

RabbitMQ配置类：

package cn.dzz.config;

import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMqConfig {

    public static final String EXCHANGE_NAME = "boot-topic-exchange";
    public static final String QUEUE_NAME = "boot-topic-queue";

    // 注入队列
    @Bean("bootQueue")
    public Queue springBootQueue() {
        return QueueBuilder.durable(QUEUE_NAME).build();
    }

    // 注入交换机
    @Bean("bootTopicExchange")
    public Exchange springBootExchange() {
        return ExchangeBuilder
                .topicExchange(EXCHANGE_NAME)
                .durable(true)
                .build();
    }

    // 交换机与队列绑定
    @Bean
    public Binding bindingExchangeAndQueue(@Qualifier("bootQueue") Queue q, @Qualifier("bootTopicExchange") Exchange e) {
        return BindingBuilder
                .bind(q) // 绑定哪个队列
                .to(e) // 给哪个交换机
                .with("boot.#") // 路由分配方式
                .noargs(); // 声明无参数
    }

}

测试类：

import cn.dzz.Producer;
import cn.dzz.config.RabbitMqConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest(classes = Producer.class)
@RunWith(SpringRunner.class)
public class ProducerTest {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void sendMessage() {
        rabbitTemplate.convertAndSend(RabbitMqConfig.EXCHANGE_NAME, "boot.info", " 发送出去消息。。。。 ");
    }

}

执行完测试类之后，检查RabbitMQ面板上面是否还有信息：

 

 

编写SpringBoot消费者服务：

编写启动类：

package cn.dzz;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

编写接收的监听器类：

package cn.dzz;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class RabbitMqListener {

    @RabbitListener(queues = "boot-topic-queue")
    public void ListenerQueue(Message message) {
        System.out.println(message);
    }
}

IDEA这里还提示出结构信息：

 

打开可以看见：

 执行启动类查看消息接收：
