springboot怎么使用消息中间件

这篇文章主要介绍springboot怎么使用消息中间件，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

前言

使用SpringBoot集成rabbitmq实现一个发送和接收

内容

1.引入依赖

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

2.application.properties

#rabbitmq配置spring.application.name=springboot-mqspring.rabbitmq.host=192.168.17.129spring.rabbitmq.port=5672spring.rabbitmq.username=mytestspring.rabbitmq.password=mytest

3.rabbitmap配置类

import org.springframework.amqp.core.Queue;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class RabbitMQConfig { @Bean public Queue mqQueue(){  return new Queue("mqboot"); }}

4.发送类< 大专栏 zyzx(53)-springboot使用消息中间件/h6>

@Componentpublic class Sender { @Autowired private AmqpTemplate rabbitTemplate; public void send(){  String content = "send: hello"+new Date();  System.out.println("Sender:"+content)  this.rabbitTemplate.convertAndSend("mqboot",content); }}

收类

@Component@RabbitListener(queues = "mqboot")public class Receiver { @RabbitHandler public void process(String data){  System.out.println("Receiver:"+data); }}

6.测试

启动springBoot

如下表明:连接成功:

@RunWith(SpringRunner.class)@SpringBootTestpublic class ApplicationTests { @Autowired private TeacherRepository teacherRepository; /*@Autowired private JavaMailSender javaMailSender;*/ @Autowired private Sender sender; @Test public void contextLoads() {  //mq测试  sender.send(); }}
