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

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。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.itheima</groupId><artifactId>spring-rabbitmq</artifactId><version>1.0-SNAPSHOT</version><dependencies><!--spring 上下文--><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.2.10.RELEASE</version></dependency><!--spring整合amqp--><dependency><groupId>org.springframework.amqp</groupId><artifactId>spring-rabbit</artifactId><version>2.1.8.RELEASE</version></dependency><!--测试--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>5.2.10.RELEASE</version></dependency></dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version><configuration><source>1.8</source><target>1.8</target></configuration></plugin></plugins></build></project>

提醒一下：pom.xml的文件在下面这个位置

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

rabbitmq.properties

rabbitmq.host=127.5.19.118  (服务器ip)
rabbitmq.port=5672  （rabbitmq端口）
rabbitmq.username=admin   （rabbitmq用户名）
rabbitmq.password=11111  （rabbitmq密码）
rabbitmq.virtual-host=/itcast  （rabbitmq虚拟机）

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@Autowiredprivate RabbitTemplate rabbitTemplate;@Testpublic void testProducer() throws InterruptedException {Integer i = 0;while (true) {Thread.sleep(5 * 1000);i++;rabbitTemplate.convertAndSend("spring_queue","消息发送了"+i);}}@Testpublic void testFanout() {rabbitTemplate.convertAndSend("spring_fanout_exchange","","fanout消息已经发送了");}@Testpublic 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

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