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

application.properties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/
