Springboot 整合 Rabbitmq消息队列

一、创建SpringBoot项目，并引入依赖

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

 

二、pom.xml配置

#配置rabbitMq 服务器
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    #虚拟host 可以不设置,使用server默认host
    virtual-host: /
    publisher-confirms: true
    publisher-returns: true
    listener:
      simple:
        acknowledge-mode: manual
        concurrency: 1
        max-concurrency: 10
        retry:
          enabled: true

 

三、普通工作队列模式

1、首先在工程中新建RabbitConfig文件

 1 import org.springframework.amqp.core.*;
 2 import org.springframework.context.annotation.Bean;
 3 import org.springframework.context.annotation.Configuration;
 4 
 5 /**
 6  * @author 
 7  * @date 
 8  * @description rabbitmq配置类
 9  */
10 @Configuration
11 public class RabbitConfig {
12 
13     /**
14      * 定义队列名
15      */
16     private final static String STRING = "string";
17 
18 
19     /**
20      * 定义string队列
21      * @return
22      */
23     @Bean
24     public Queue string() {
25         return new Queue(STRING);
26     
27 }

 

2、创建生产者

 1 import org.springframework.amqp.core.AmqpTemplate;
 2 import org.springframework.beans.factory.annotation.Autowired;
 3 import org.springframework.stereotype.Component;
 4 
 5 import javax.xml.ws.Action;
 6 import java.text.SimpleDateFormat;
 7 import java.util.Date;
 8 
 9 /**
10  * @author 
11  * @date 
12  * @description rabbit消息生产者
13  */
14 @Component
15 public class RabbitProducer {
16 
17     @Autowired
18     private AmqpTemplate rabbitTemplate;
19 
20     public void stringSend() {
21         Date date = new Date();
22         String dateString = new SimpleDateFormat("YYYY-mm-DD hh:MM:ss").format(date);
23         System.out.println("[string] send msg:" + dateString);  
24       // 第一个参数为刚刚定义的队列名称
25         this.rabbitTemplate.convertAndSend("string", dateString);
26     }
27 }

 

3、创建消费者

 1 import org.springframework.amqp.core.AmqpTemplate;
 2 import org.springframework.amqp.rabbit.annotation.RabbitHandler;
 3 import org.springframework.amqp.rabbit.annotation.RabbitListener;
 4 import org.springframework.beans.factory.annotation.Autowired;
 5 import org.springframework.stereotype.Component;
 6 
 7 /**
 8  * @author 
 9  * @date 
10  * @description rabbitmq消费者 @RabbitListener(queues = "simpleMsg") 监听名simpleMsg的队列
11  */
12 @Component
13 @RabbitListener(queues = "string")
14 public class StringConsumer {
15 
16     @Autowired private AmqpTemplate rabbitmqTemplate;
17 
18     /**
19      * 消息消费
20      * @RabbitHandler 代表此方法为接受到消息后的处理方法
21      */
22     @RabbitHandler
23     public void recieved(String msg) {
24         System.out.println("[string] recieved message:" + msg);
25     }
26 
27 }

4、调用

 1 @RestController
 2 public class TestController {
 3 
 4     @Autowired
 5     private RabbitProducer producer;
 6 
 7     @RequestMapping("/test")
 8     public void test(){
 9         for (int i = 0; i < 10; i++) {
10             producer.stringSend();
11         }
12     }
13 }
