SpringBoot停止启动时测试检查rabbitmq

问题

在Springboot项目中配置rabbitmq后，总是在每次启动时自动测试MQ的连接，如果测试不通过，就一直重连，导致项目无法正常启动。自己在开发与MQ无关的功能时，无法正常进行，十分耽误时间。如下所示：

查找了很多地方，这里记录一下，如何在Springboot启动项目时，如何关闭RabbitMq的连接测试。

解决

在配置文件里增加

spring.rabbitmq.listener.direct.auto-startup= false
spring.rabbitmq.listener.simple.auto-startup= false

这样启动时就不会每次都检查RabbitMq是否可以连接了

RabbitMQ的简单使用的Demo

当前使用的版本：rabbitmq-server-windows-3.8.3

1.声明

当前内容用于本人学习和使用RabbitMQ这个消息队列，当前内容为SpringBoot操作RabbitMQ的基本操作

本人使用windows10方式使用RabbitMQ

2.创建一个测试账户

在这里插入图片描述

注意这里的Can access virtual hosts必须修改为/，否则可能出现连接失败，这里使用账户为root

3.pom依赖

		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

4.配置文件application.properties

spring.application.name=rabbitmq-hello
server.port=8080
spring.rabbitmq.host
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=root
spring.rabbitmq.password=root

5.创建入口类

@RestController
@SpringBootApplication
public class RabbitMQApplication {
	@Autowired
	AmqpTemplate amqpTemplate;
	@RequestMapping("/send")
	public String send(String msg) {
		amqpTemplate.convertAndSend("test", msg);
		return "发送消息成功：===>" + msg;
	}
	public static void main(String[] args) {
		SpringApplication.run(RabbitMQApplication.class, args);
	}
	@Bean
	Queue queue() {
		return new Queue("test");
	}
	@Component
	@RabbitListener(queues = "test")
	class MsgCustomer {
		@RabbitHandler
		public void handlerMsg(String msg) {
			System.out.println("消息消费者消费===>" + msg);
		}
	}
}

6.测试

在这里插入图片描述

7.总结

1.通过使用SpringBoot操作RabbitMQ的时候非常简单，直接使用AmqpTemplate即可

2.通过@RabbitListener指定需要监听的队列，通过@RabbitHandler方式处理监听后的数据

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
