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

SpringBoot停止启动时测试检查rabbitmq操作

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

<parent>

	</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);
		}
	}
}
