【RabbitMQ】06 Spring整合RabbitMQ
首先生产者和消费者需要的Maven依赖是一样的
<?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"> <parent> <artifactId>RabbitMQ</artifactId> <groupId>cn.dzz</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>Spring-RabbitMQ-Producer</artifactId> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.3.10</version> </dependency> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-rabbit</artifactId> <version>2.1.8.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.3.10</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> </dependency> </dependencies> <properties> <maven.compiler.source>8</maven.compiler.source> <maven.compiler.target>8</maven.compiler.target> </properties> </project>
其次的RabbitMQ连接信息也是一致的
rabbitmq.properties
rabbitmq.host = 192.168.2.121 # 换成你的ip
rabbitmq.port = 5672
rabbitmq.username = test # 你的账号和密码
rabbitmq.password = 123456 # 你的账号和密码
rabbitmq.virtual-host = /dzz # 你设置的虚拟主机
生产者服务Spring整合：
生产者定义的Spring.xml文件（文件名随意 这里我取的是producer-config.xml）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit.xsd"> <!--加载配置文件--> <context:property-placeholder location="classpath:rabbitmq.properties"/> <!-- 定义rabbitmq connectionFactory --> <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}" port="${rabbitmq.port}" username="${rabbitmq.username}" password="${rabbitmq.password}" virtual-host="${rabbitmq.virtual-host}" publisher-confirms="true" publisher-returns="true" /> <!--定义管理交换机、队列--> <rabbit:admin connection-factory="connectionFactory"/> <!--定义rabbitTemplate对象操作可以在代码中方便发送消息--> <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/> <!-- 简单模式队列 不存在时自动创建 交换机默认DIRECT 名字 “” 路由键就是队列的名称 --> <rabbit:queue id="spring-queue" name="spring-queue" auto-declare="true" /> <!-- 广播订阅模式队列 --> <rabbit:queue id="spring-fanout-queue-1" name="spring-fanout-queue-1" auto-declare="true" /> <rabbit:queue id="spring-fanout-queue-2" name="spring-fanout-queue-2" auto-declare="true" /> <rabbit:fanout-exchange name="spring-fanout-exchange" id="spring-fanout-exchange" auto-declare="true"> <rabbit:bindings> <rabbit:binding queue="spring-fanout-queue-1"/> <rabbit:binding queue="spring-fanout-queue-2"/> </rabbit:bindings> </rabbit:fanout-exchange> <!-- 通配符Topic模式队列 --> <rabbit:queue id="spring-topic-queue-1" name="spring-topic-queue-1" auto-declare="true" /> <rabbit:queue id="spring-topic-queue-2" name="spring-topic-queue-2" auto-declare="true" /> <rabbit:queue id="spring-topic-queue-3" name="spring-topic-queue-3" auto-declare="true" /> <rabbit:topic-exchange name="spring-topic-exchange" id="spring-topic-exchange" auto-declare="true"> <rabbit:bindings> <rabbit:binding pattern="heima.*" queue="spring-topic-queue-1"/> <rabbit:binding pattern="heima.#" queue="spring-topic-queue-2"/> <rabbit:binding pattern="itcast.#" queue="spring-topic-queue-3"/> </rabbit:bindings> </rabbit:topic-exchange> </beans>
然后编写对应的测试类：
注意测试类编写要注入xml文件，文件名称别写错
package cn.dzz; 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; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath*:producer-config.xml") public class SpringProducerTest { @Autowired private RabbitTemplate rabbitTemplate; /** * 简单模式消息发送 */ @Test public void simpleTest() { rabbitTemplate.convertAndSend("spring-queue", "hello spring integrate rabbitmq ...."); } /** * fanout广播订阅消息发送 */ @Test public void fanoutTest() { rabbitTemplate.convertAndSend("spring-fanout-exchange", "", "hello spring integrate rabbitmq ...."); } /** * topic通配符消息发送 */ @Test public void topicTest() { rabbitTemplate.convertAndSend("spring-topic-exchange", "itcast.info", "hello spring integrate rabbitmq ...."); } }
依次执行之后就会在RabbitMQ中加载相应的交换机和队列信息：
消费者服务Spring整合：
消费者的Spring.xml配置信息（consumer-config.xml）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit.xsd"> <!--加载配置文件--> <context:property-placeholder location="classpath:rabbitmq.properties"/> <!-- 定义rabbitmq connectionFactory --> <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}" port="${rabbitmq.port}" username="${rabbitmq.username}" password="${rabbitmq.password}" virtual-host="${rabbitmq.virtual-host}"/> <context:component-scan base-package="cn.dzz.rabbitmq.listener" /> <!--定义监听器容器--> <rabbit:listener-container connection-factory="connectionFactory" auto-declare="true"> <rabbit:listener ref="simpleQueueListener" queue-names="spring-queue" /> <rabbit:listener ref="fanoutListener1" queue-names="spring-fanout-queue-1" /> <rabbit:listener ref="fanoutListener2" queue-names="spring-fanout-queue-2" /> <rabbit:listener ref="topicListener1" queue-names="spring-topic-queue-1" /> <rabbit:listener ref="topicListener2" queue-names="spring-topic-queue-2" /> <rabbit:listener ref="topicListener3" queue-names="spring-topic-queue-3" /> </rabbit:listener-container> </beans>
这个监听器编写太累了，一个监听器就要写一个类来实现：
其余的广播监听器和通配符监听器都是一样的，不重复贴上来了
package cn.dzz.rabbitmq.listener; import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; import org.springframework.stereotype.Component; import java.nio.charset.StandardCharsets; @Component public class SimpleQueueListener implements MessageListener { @Override public void onMessage(Message message) { // 监听到消息之后要触发的回调逻辑 byte[] body = message.getBody(); System.out.println("简单模式队列1监听：" + new String(body, StandardCharsets.UTF_8)); } }
消费者测试类编写：
import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath*:consumer-config.xml") public class SpringConsumerTest { @Test public void simpleListenerTest() { System.out.println("监听测试"); } }
这里很奇怪，和视频不太一样，视频里面程序跑起来不需要停止就能收到简单模式的消息
但是在我这里只能在程序结束以后看到：
