Spring Boot Sample 027之spring-boot-mq-rabbitmq
一、环境
- Idea 2020.1
- JDK 1.8
- maven
二、目的
spring boot 通过整合rabbitMQ
gitHub地址： https://github.com/ouyushan/ouyushan-spring-boot-samples
三、步骤
3.1、点击File -> New Project -> Spring Initializer，点击next
3.2、在对应地方修改自己的项目信息
3.3、选择Web依赖，选中Spring Web、Spring Boot DevTools、Spring for RabbitMQ。可以选择Spring Boot版本，本次默认为2.3.0，点击Next
3.4、项目结构
四、添加文件
pom.xml文件

RabbitMqConfig.java
package org.ouyushan.springboot.mq.rabbitmq.config;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* @Description:
* @Author: ouyushan
* @Email: ouyushan@hotmail.com
* @Date: 2020/6/8 10:18
*/
@Configuration
public class RabbitMqConfig {
@Bean
public Queue kinsonQueue() {
return new Queue("ouyushan.queue");
}
}
mq消费监听器
RabbitMQConsumerListener.java
package org.ouyushan.springboot.mq.rabbitmq.listener;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/**
* @Description:
* @Author: ouyushan
* @Email: ouyushan@hotmail.com
* @Date: 2020/6/4 16:46
*/
@Component
public class RabbitMQConsumerListener {
private static Logger logger = LoggerFactory.getLogger(RabbitMQConsumerListener.class);
/* 接收消息 */
@RabbitListener(queues = "ouyushan.queue")
public void receiveQueue(String text) {
logger.info("接受到：" + text);
}
}
通过接口调用模拟mq生产者
RabbitMQProducerController.java
package org.ouyushan.springboot.mq.rabbitmq.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @Description:
* @Author: ouyushan
* @Email: ouyushan@hotmail.com
* @Date: 2020/6/4 16:47
*/
@RestController
public class RabbitMQProducerController {
private static Logger logger = LoggerFactory.getLogger(RabbitMQProducerController.class);
@Autowired
private AmqpTemplate amqpTemplate;
/* 发送消息 */
@RequestMapping(value = "/sendMsg")
public void send(String msg) {
this.amqpTemplate.convertAndSend("ouyushan.queue", msg);
logger.info("msg:" + msg);
}
}
五、测试
SpringBootMqRabbitmqApplicationTests.java
package org.ouyushan.springboot.mq.rabbitmq;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
@SpringBootTest
@AutoConfigureMockMvc
class SpringBootMqRabbitmqApplicationTests {
@Test
public void testMQProducer(@Autowired MockMvc mockMvc) throws Exception {
mockMvc.perform(MockMvcRequestBuilders.get("/sendMsg?msg=sendMSG")
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andDo(print());
}
}
执行测试方法后，控制台打印：
2020-06-08 10:40:16.266 INFO 8004 --- [ main] o.o.s.m.r.c.RabbitMQProducerController : msg:sendMSG
2020-06-08 10:40:16.312 INFO 8004 --- [ntContainer#0-1] o.o.s.m.r.l.RabbitMQConsumerListener : 接受到：sendMSG
创建项目后运行SpringBootMqRabbitmqApplication.java类， 然后访问 - get请求 - localhost:8080/sendMsg?msg=sendMSG 登录后台管理 账号/密码 guest/ http://localhost:15672/
