前言
提示：Springboot集成Rabbitmq实战案例，通过接口调用的方式演示。
提示：以下是本篇文章正文内容，下面案例可供参考
一、集成步骤
一、生产者：
-
创建生产者SpringBoot工程
-
引入pom依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> -
编写rabbitmq配置消息
-
定义交换机，队列以及绑定关系的配置类
-
注入RabbitTemplate，调用方法，完成消息发送
二、消费者：
-
创建生产者SpringBoot工程
-
引入pom依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> -
编写rabbitmq配置消息
-
定义监听类，使用@RabbitListener注解完成队列监听。
二、实现步骤
1.项目架构图
2.创建项目
代码如下（示例）：
1.pom依赖

4.消费端component
package com.sky.springbootrabbitmqmodule.component;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
@Component
public class ConcumerReceiver {
//直连模式的多个消费者，会分到其中一个消费者进行消费。类似task模式
//通过注入RabbitContainerFactory对象，来设置一些属性，相当于task里的channel.basicQos
@RabbitListener(queues="helloWorldqueue")
public void helloWorldReceive(String message) {
System.out.println("helloWorld模式 received message : " +message);
}
//工作队列模式
@RabbitListener(queues="work_sb_mq_q")
public void wordQueueReceiveq1(String message) {
System.out.println("工作队列模式1 received message : " +message);
}
@RabbitListener(queues="work_sb_mq_q")
public void wordQueueReceiveq2(String message) {
System.out.println("工作队列模式2 received message : " +message);
}
//pub/sub模式进行消息监听
@RabbitListener(queues="fanout.q1")
public void fanoutReceiveq1(String message) {
System.out.println("发布订阅模式1received message : " +message);
}
@RabbitListener(queues="fanout.q2")
public void fanoutReceiveq2(String message) {
System.out.println("发布订阅模式2 received message : " +message);
}
//Routing路由模式
@RabbitListener(queues="direct_sb_mq_q1")
public void routingReceiveq1(String message) {
System.out.println("Routing路由模式routingReceiveqOne received message : " +message);
}
@RabbitListener(queues="direct_sb_mq_q2")
public void routingReceiveq2(String message) {
System.out.println("Routing路由模式routingReceiveqTwo received message : " +message);
}
//topic 模式
//注意这个模式会有优先匹配原则。例如发送routingKey=hunan.IT,那匹配到hunan.*(hunan.IT,hunan.eco),之后就不会再去匹配*.ITd
@RabbitListener(queues="topic_sb_mq_q1")
public void topicReceiveq1(String message) {
System.out.println("Topic模式 topic_sb_mq_q1 received message : " +message);
}
@RabbitListener(queues="topic_sb_mq_q2")
public void topicReceiveq2(String message) {
System.out.println("Topic模式 topic_sb_mq_q2 received message : " +message);
}
}
5.生产者controller
package com.sky.springbootrabbitmqmodule.controller;
import org.springframework.amqp.AmqpException;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.io.UnsupportedEncodingException;
@RestController
public class ProducerController {
@Autowired
private RabbitTemplate rabbitTemplate;
//helloWorld 直连模式
@GetMapping(value="/helloWorldSend")
public Object helloWorldSend(String message) throws AmqpException, UnsupportedEncodingException {
//设置部分请求参数
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//发消息
rabbitTemplate.send("helloWorldqueue",new Message(message.getBytes("UTF-8"),messageProperties));
return "message sended : "+message;
}
//工作队列模式
@GetMapping(value="/workqueueSend")
public Object workqueueSend(String message) throws AmqpException, UnsupportedEncodingException {
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//制造多个消息进行发送操作
for (int i = 0; i <10 ; i++) {
rabbitTemplate.send("work_sb_mq_q", new Message(message.getBytes("UTF-8"),messageProperties));
}
return "message sended : "+message;
}
// pub/sub 发布订阅模式 交换机类型 fanout
@GetMapping(value="/fanoutSend")
public Object fanoutSend(String message) throws AmqpException, UnsupportedEncodingException {
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("fanoutExchange", "", new Message(message.getBytes("UTF-8"),messageProperties));
return "message sended : "+message;
}
//routing路由工作模式 交换机类型 direct
@GetMapping(value="/directSend")
public Object routingSend(String routingKey,String message) throws AmqpException, UnsupportedEncodingException {
if(null == routingKey) {
routingKey="directBind.one";
}
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("directExchange", routingKey, new Message(message.getBytes("UTF-8"),messageProperties));
return "message sended : routingKey >"+routingKey+";message > "+message;
}
//topic 工作模式 交换机类型 topic
@GetMapping(value="/topicSend")
public Object topicSend(String routingKey,String message) throws AmqpException, UnsupportedEncodingException {
if(null == routingKey) {
routingKey="directBind.one";
}
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("topicExchange", routingKey, new Message(message.getBytes("UTF-8"),messageProperties));
return "message sended : routingKey >"+routingKey+";message > "+message;
}
}
上面就是这个项目的所有代码了，下面就是Demo演示内容。
三、演示步骤
1.启动项目
2.调用接口演示
1.直连模式
1.接口调用
2.控制台打印
2.工作队列模式
1.接口调用
2.控制台打印
3.发布订阅模式（交换机类型：fanout）
1.接口调用
2.控制台打印
4.路由工作模式（交换机类型：direct）
1.接口调用
2.控制台打印
5.通配符模式（交换机类型：topic）
1.接口调用
2.控制台打印
除此之外，我还提供了项目地址提供给大家clone，地址链接：https://gitee.com/java_wxid/liao
