添加依赖

修改 pom.xml 文件内容为如下:

<?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.haicoder</groupId> <artifactId>spring-rabbitmq-producers</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-rabbit</artifactId> <version>2.1.8.RELEASE</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.1.7.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>

配置整合

创建 spring-rabbitmq-producer\src\main\resources\properties\rabbitmq.properties 连接参数等配置文件:

rabbitmq.host=106.15.72.229 rabbitmq.port=5672 rabbitmq.username=heima rabbitmq.password=heima rabbitmq.virtual-host=/itcast

创建 spring-rabbitmq-producer\src\main\resources\spring-rabbitmq.xml 整合配置文件:

发送消息

创建测试文件 spring-rabbitmq-producer\src\test\java\com\haicoder\rabbitmq\ProducerTest.java

package com.haicoder; 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:spring-rabbitmq-producer.xml") public class ProducerTest { //1.注入 RabbitTemplate @Autowired private RabbitTemplate rabbitTemplate; @Test public void testHelloWorld(){ //2.发送消息 rabbitTemplate.convertAndSend("spring_queue","hello world spring...."); } /** * 发送fanout消息 */ @Test public void testFanout(){ //2.发送消息 rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout...."); } /** * 发送topic消息 */ @Test public void testTopics(){ //2.发送消息 rabbitTemplate.convertAndSend("spring_topic_exchange","heima.hehe.haha","spring topic...."); rabbitTemplate.convertAndSend("spring_topic_exchange","itcast.hehe.haha","spring topic...."); } }

井号通配符监听器

创建 spring-rabbitmq-consumer\src\main\java\com\haicoder\rabbitmq\listener\TopicListenerWell.java

import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; public class TopicListenerWell implements MessageListener { @Override public void onMessage(Message message) { try { String msg = new String(message.getBody(), "utf-8"); System.out.printf("通配符#监听器:接收路由名称为:%s,路由键为:%s,队列名为:%s的消息:%s \n", message.getMessageProperties().getReceivedExchange(), message.getMessageProperties().getReceivedRoutingKey(), message.getMessageProperties().getConsumerQueue(), msg); } catch (Exception e) { e.printStackTrace(); } } }

井号通配符监听器2

创建 spring-rabbitmq-consumer\src\main\java\com\haicoder\rabbitmq\listener\TopicListenerWell2.java

import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; public class TopicListenerWell2 implements MessageListener { @Override public void onMessage(Message message) { try { String msg = new String(message.getBody(), "utf-8"); System.out.printf("通配符#监听器2:接收路由名称为:%s,路由键为:%s,队列名为:%s的消息:%s \n", message.getMessageProperties().getReceivedExchange(), message.getMessageProperties().getReceivedRoutingKey(), message.getMessageProperties().getConsumerQueue(), msg); } catch (Exception e) { e.printStackTrace(); } } }

测试

启动测试类

package com.haicoder; 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:spring-rabbitmq-consumer.xml") public class ConsumerTest { @Test public void test1(){ boolean flag = true; while (true){ } } }
