springboot集成RabbitMQ

一、安装RabbitMQ服务端
1、首先需要安装erlang，请去官网下载：下载链接
2、安装RabbitMQ服务端：下载链接
3、（管理员）安装完后找到D:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.9\sbin
4、安装管理插件：运行 rabbitmq-plugins.bat enable rabbitmq_management
5、重启：net stop RabbitMQ && net start RabbitMQ
6、创建新用户和密码:rabbitmqctl.bat add_user username password
7、用户授权:rabbitmqctl set_permissions -p / username .* .* .*,否则无法连接和读写消息；
8、赋予管理员角色：rabbitmqctl set_user_tags user_admin administrator，用于登录后台
二、建立springboot工程
1、依赖

        
            org.springframework.boot
            spring-boot-starter-amqp
        

2、properties配置

server.port=8672
spring.application.name=rabbitmq

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=lzz
spring.rabbitmq.password=lzz_heaven304

spring.rabbitmq.template.retry.enabled=true
spring.rabbitmq.template.retry.initial-interval=2s

3、开启rabitMQ：@EnableRabbit
4、rabbitconfig

@Configuration
public class RabbitConfig {

    @Bean
    public Queue queue(){
        return new Queue("test");
    }
}

5、MessageSendService

@Slf4j
@Service
public class MessageSendService {

    @Autowired
    private AmqpTemplate amqpTemplate;


    public void sendMessage(String message){
        log.info("message is {}",message);
        amqpTemplate.convertAndSend("test",message);
    }
}

7、MessageReceiverService

@Service
@RabbitListener(queues="test")
@Slf4j
public class MessageReceiverService {

    @Autowired
    private AmqpTemplate amqpTemplate;

    @RabbitHandler
    public void receiverMessage(String message){
        log.info("message is {}",message);
    }
}

8、Controller接口暴露

@RestController
public class MessageController {

    @Autowired
    private MessageSendService sendService;

    @RequestMapping(value = "/test")
    public void sendMessage(String message){
        sendService.sendMessage(message);
    }
}

9、这里还会存在An unexpected connection driver error occured和socket close异常
**解决方案:**刚才已经下载插件了，只需要登录后台:http://localhost:15672/#/login
在queues目录下，新建一个queue，命名记得与@RabbitListener中的queue一样，即可完成消息发送与消费
