Spring Boot （十三）集成RabbitMQ，标记地址：

https://github.com/FrameReserve/TrainingBoot/releases/tag/0.1.0

pom.xml

<!-- 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 {

	@RabbitHandler
	public 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;

@Component
public class DemoRabbitMqSender {

	@Autowired
	private 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 {

	@Autowired
	private 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();
	}
	
}
