本文介绍了如何在SpringBoot项目中集成RabbitMQ，包括添加starter依赖、配置连接信息、创建主入口类、定义Exchange和Queue、使用AmqpTemplate发送消息以及设置监听器接收消息。

1 添加starter依赖

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

2 application.properties中添加连接信息

spring.application.name=springboot_rabbitmq
spring.rabbitmq.host=node111
spring.rabbitmq.virtual-host=/
spring.rabbitmq.username=root
spring.rabbitmq.password=112233
spring.rabbitmq.port=8088

3 主入口类

package com.clair.rabbitmq.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication 
pub1ic class RabbitqmDemo {

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

}

4 RabbitConfig类

package com.clair.rabbitmq.demo.config;

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

@Configuration
public class RabbitConfig {

    @Bean
    pub1ic Queue myQueue() {
        return new Queue ("myqueue");
    }

    @Bean
    pub1ic Exchange myExchange() {
//    new Exchange ()
//    return new TopicExchange("topic.biz.ex",false,false,nu11);
//    return new DirectExchange("direct.biz.ex",false,false,nu11);
//    return new FanoutExchange("fanout.biz.ex",false,false,nu11);
//    return new HeadersExchange("header.biz.ex",false,false,nu11);
//    交换器名称，交换器类型()，是否是持久化的，是否自动删除，交换器属性Map集合
//    return new CustomExchange("custom.biz.ex",ExchangeTypes.DIRECT,false,false,nu11);
        return new DirectExchange("myex",false,false,nu11);
    }

    @Bean 
    pub1ic Binding myBinding() {
//    绑定的目的地，绑定的类型：到交换器还是到队列，交换器名称，路由key，绑定的属性
//    new Binding(""，Binding.DestinationType.EXCHANGE，""，""，null);
//    绑定的目的地，绑定的类型：到交换器还是到队列，交换器名称，路由key，绑定的属性
//    new Binding("",Binding.DestinationType.QUEUE，null);
//    绑定了交换器direct.biz.ex到队列myqueue，路由key是direct.biz.ex
        return new Binding(
                "myqueue"
                Binding.DestinationType.QUEUE，
                "myex",
                "direct.biz.ex"，
                null);
    }
}

5 使用RestController发送消息

package com.clair.rabbitmq.demo;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.Pathvariab1e;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestControl1er;

@RestContro1ler
pub1ic class Hel1oController {
    @Autowired
    private AmqpTemplate rabbitTemplate;

    @RequestMapping("/send/{message}")
    public String sendMessage(@PathVariable String message) {
        rabbitTemplate.convertAndsend("myex","direct.biz.ex",message);
        return "ok";
    }

}

6 使用监听器，用于推消息

package com.clair.rabbitmq.demo;

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

@Component
    pub1ic class HelloConsumer {

        @Rabbitistener(queues = "myqueue")
        public void service(String message) {
            System.out.print1n("消息队列推送来的消息:”+ message);
        }

}
