一、添加依赖

        <!--AMQP依赖，包含RabbitMQ--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency><!-- 引入knife4j-spring-ui包 /doc.html--><dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-spring-boot-starter</artifactId><version>3.0.3</version></dependency>

二、配置文件中添加RabbitMQ访问配置

spring.rabbitmq.host=192.168.0.104
spring.rabbitmq.port=5672
spring.rabbitmq.virtual-host=/
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin123

三、消息生产者代码

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;@Api(tags = "生产者服务")
@RestController
public class ProducerController {@Autowiredprivate RabbitTemplate rabbitTemplate;@ApiOperation(value = "基本消息模型")@PostMapping("/testHello")public String testHello() {rabbitTemplate.convertAndSend("hello","hello world");return "ok";}@ApiOperation(value = "work消息模型")@PostMapping("/testWork")public String testWork() {for (int i = 0; i < 10; i++) {rabbitTemplate.convertAndSend("work","hello work!");}return "ok";}@ApiOperation(value = "订阅模型-Fanout 广播模式")@PostMapping("/testFanout")public String testFanout() {rabbitTemplate.convertAndSend("logs","","这是日志广播");return "ok";}@ApiOperation(value = "订阅模型-Direct")@PostMapping("/testDirect")public String testDirect() {rabbitTemplate.convertAndSend("directs","error","error 的日志信息");return "ok";}@ApiOperation(value = "订阅模型-Topic")@PostMapping("/testTopic")public String testTopic() {rabbitTemplate.convertAndSend("topics","user.save.findAll","user.save.findAll 的消息");return "ok";}
}

四、消息消费者代码

import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;@Component
public class SpringRabbitListener {//基本消息模型@RabbitListener(queuesToDeclare = @Queue("hello"))public void receive(String message) {System.out.println("message = " + message);}//work消息模型@RabbitListener(queuesToDeclare = @Queue("work"))public void workReceive1(String message) {System.out.println("workReceive1 message = " + message);}//work消息模型@RabbitListener(queuesToDeclare = @Queue("work"))public void workReceive2(String message) {System.out.println("workReceive2 message = " + message);}//订阅模型-Fanout 广播模式@RabbitListener(bindings = @QueueBinding(value = @Queue, exchange = @Exchange(name="logs",type = "fanout")))public void fanoutReceive(String message) {System.out.println("fanoutReceive message = " + message);}//订阅模型-Direct@RabbitListener(bindings ={@QueueBinding(value = @Queue(),key={"info","error"},exchange = @Exchange(type = "direct",name="directs"))})public void directReceive(String message) {System.out.println("directReceive message = " + message);}//订阅模型-Topic@RabbitListener(bindings = {@QueueBinding( value = @Queue,key = {"user.*"},exchange = @Exchange(type = "topic",name = "topics"))})public void topicReceive1(String message) {System.out.println("topicReceive1 message = " + message);}//订阅模型-Topic@RabbitListener(bindings = {@QueueBinding(value = @Queue,key = {"user.#"},exchange = @Exchange(type = "topic",name = "topics"))})public void topicReceive2(String message) {System.out.println("topicReceive2 message = " + message);}}

五、验证
