springBoot使用rabbitmq

关于 rabbitmq 的学习，推荐参考https://blog.csdn.net/super_rd?t=1，这里直接进入主题

spring boot 基础 rabbitmq 主要依赖 spring-boot-starter-amqp

配置文件

配置关于rabbitmq 的连接和用户信息

spring.application.name=rabbitmq

spring.rabbitmq.addresses=192.168.86.132

spring.rabbitmq.port=5672

spring.rabbitmq.username=springcloud

spring.rabbitmq.password=springcloud

创建消息生成者sender

AmqpTemplate 接口定义了一套针对AMQP协议的基础操作

package springcloud.spring_boot_rabbitmq;

import org.springframework.amqp.core.AmqpTemplate;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

import java.util.Date;

创建消息生成者sender

AmqpTemplate 接口定义了一套针对AMQP协议的基础操作

@Component

public class Sender {

@Autowired

private AmqpTemplate amqpTemplate;

public void send(){

String context = "hello "+ new Date();

System.out.println("sender : "+context);

this.amqpTemplate.convertAndSend("shendu",context);

}

创建消息消费者 receiver,通过 @RabbitListener(queues = "shendu") 注解定义该类shendu队列的监听，并用

@RabbitHandler 注解来指定对消息的处理方法。所以该消费者实现了对shendu队列的消费

package springcloud.spring_boot_rabbitmq;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;

import org.springframework.amqp.rabbit.annotation.RabbitListener;

import org.springframework.stereotype.Component;

@Component

@RabbitListener(queues = "shendu")

public class Receiver {

@RabbitHandler

public void process(String shendu){

System.out.println("receiver: "+shendu);

}

启动类

package springcloud.spring_boot_rabbitmq;

import org.springframework.amqp.core.Queue;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.Bean;

@SpringBootApplication

public class SpringBootRabbitmqApplication {

public static void main(String[] args) {

SpringApplication.run(SpringBootRabbitmqApplication.class, args);

}

@Bean

public Queue queue(){

return new Queue("shendu");

}

pom 文件

spring-boot-starter-amqp 用于支持rabbitmq

创建单元测试

package springcloud.spring_boot_rabbitmq;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)

@SpringBootTest

public class SpringBootRabbitmqApplicationTests {

@Autowired

private Sender sender;

@Test

public void contextLoads() {

sender.send();

}

结果：

springBoot使用rabbitmq
