spring 整合 RabbitMQ 3.9.11

rabbitmq 3.9.11

创建工程

不管用什么办法创建出一个空的工程出来，或者在已有工程里面创建一个新的module，下面只说创建新module的方法。

在菜单里选择Project Structure

在这里插入图片描述

先点加号，再点New Module

然后直接下一步

然后把Module名字，所在位置都填好之后直接finish

在idea中新建Module都是这么操作。

maven配置

直接把下面的配置信息根据需要粘贴到自己的pom.xml里面。

resource 配置文件

以下三个文件直接复制下面的代码就可以，把rabbitmq配置改成自己的就好了，bean什么的写成自己的

在这里插入图片描述

Producer

为了能测试执行代码，就写在测试类里面了。

rabbitTemplate.convertAndSend("spring_fanout_exchange","","fanout消息已经发送了");
当中的
spring_fanout_exchange
是绑定的上面 spring-rabbitmq-producer.xml 当中的对应的bean （
<rabbit:fanout-exchange id="spring_fanout_exchange" name="spring_fanout_exchange" auto-declare="true">
）,有关exchange绑定 queue的配置都在
spring-rabbitmq-producer.xml
当中。

package com.itheima.springRabbitmq;

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.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @Author zhizekai
 * @Date 2022-1-11 15:48:45 15:48
 * @Version 2.0
 */

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-producer.xml")
public class ProducerTest {

    // 注入rabbitmqTemple
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testProducer() throws InterruptedException {
        Integer i = 0;
        while (true) {
            Thread.sleep(5 * 1000);

            i++;
            rabbitTemplate.convertAndSend("spring_queue","消息发送了"+i);
        }

    }

    @Test
    public void testFanout() {
        rabbitTemplate.convertAndSend("spring_fanout_exchange","","fanout消息已经发送了");
    }
    @Test
    public void testTopic() {
        rabbitTemplate.convertAndSend("spring_topic_exchange","heima.heeh.haha","topic消息已经发送了");
    }
}

Consumer

这个代码是跑起来自动监听的，实现一下
MessageListener
这个类，重写
onMessage
方法，
message.getBody()
就是消息内容

在这里插入图片描述

package com.itheima.springRabbitmq.consumer;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

/**
 * @Author zhizekai
 * @Date 2022-1-11 18:53:33 18:53
 * @Version 2.0
 */
public class SpringQueueListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        System.out.println("收到的消息："+new String(message.getBody()));
//        System.out.println(message.toString());
    }
}

测试代码

package com.itheima.springRabbitmq.consumer;

import junit.framework.TestCase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @Author zhizekai
 * @Date 19:01
 * @Version 2.0
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-consumer.xml")
public class SpringQueueListenerTest{

    @Test
    public void testOnMessage() throws InterruptedException {
        boolean flag = true;
        while (true) {
            Thread.sleep(5 * 1000);
            System.out.println("正在监听");
        }

    }
}
