<!-- Rabbit MQ -->        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency>

Spring Boot配置文件application.yml：

src/main/resources/application.yml

    rabbitmq:        host: 192.168.2.71        port: 5672        username: hxb        password: hxb

RabbitMQ接收方法：

src/main/java/com/training/rabbitmq/receiver/DemoRabbitMqReceiver.java

package com.training.rabbitmq.receiver;import org.springframework.amqp.rabbit.annotation.RabbitHandler;import org.springframework.amqp.rabbit.annotation.RabbitListener;import org.springframework.stereotype.Component;/** * 消息队列接收类 */@Component@RabbitListener(queues = "hello")public class DemoRabbitMqReceiver {@RabbitHandlerpublic void process(String content) {System.out.println("Receiver : " + content);}}

RabbitMQ 发送方法：

src/main/java/com/training/rabbitmq/sender/DemoRabbitMqSender.java

package com.training.rabbitmq.sender;import org.springframework.amqp.core.AmqpTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;@Componentpublic class DemoRabbitMqSender {@Autowiredprivate AmqpTemplate rabbitTemplate;public void send(String content) {System.out.println("Sender : " + content);this.rabbitTemplate.convertAndSend("hello", content);}}

测试 Rabbit MQ：

src/main/java/com/training/rabbitmq/controller/DemoRabbitMqController.java

package com.training.rabbitmq.controller;import io.swagger.annotations.ApiOperation;import javax.servlet.http.HttpSession;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.RestController;import com.training.core.dto.ResultDataDto;import com.training.rabbitmq.sender.DemoRabbitMqSender;/** * 测试Rabbit MQ */@RestController@RequestMapping(value="/rabbitmq")public class DemoRabbitMqController {@Autowiredprivate DemoRabbitMqSender demoRabbitMqSender;/** * 发送测试消息队列 */@ApiOperation(value="发送测试消息队列", notes="addEntity")    @RequestMapping(value = "/addRabbitMq", method = RequestMethod.GET)public @ResponseBody ResultDataDto addEntity(HttpSession httpSession) {demoRabbitMqSender.send("jkljklkjljjkljl");return ResultDataDto.addAddSuccess();}}
