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：

org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection timed out: connect at org.springframework.amqp.rabbit.support.RabbitExceptionTranslator.convertRabbitAccessException(RabbitExceptionTranslator.java:62) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:484) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.connection.CachingConnectionFactory.createConnection(CachingConnectionFactory.java:628) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.connection.ConnectionFactoryUtils.createConnection(ConnectionFactoryUtils.java:240) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.core.RabbitTemplate.doExecute(RabbitTemplate.java:1816) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.core.RabbitTemplate.execute(RabbitTemplate.java:1790) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.core.RabbitTemplate.execute(RabbitTemplate.java:1771) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.core.RabbitAdmin.getQueueProperties(RabbitAdmin.java:345) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.listener.AbstractMessageListenerContainer.redeclareElementsIfNecessary(AbstractMessageListenerContainer.java:1604) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer$AsyncMessageProcessingConsumer.run(SimpleMessageListenerContainer.java:995) [spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_231]Caused by: java.net.ConnectException: Connection timed out: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) ~[na:1.8.0_231] at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) ~[na:1.8.0_231] at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) ~[na:1.8.0_231] at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) ~[na:1.8.0_231] at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) ~[na:1.8.0_231] at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) ~[na:1.8.0_231] at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) ~[na:1.8.0_231] at java.net.Socket.connect(Socket.java:606) ~[na:1.8.0_231] at com.rabbitmq.client.impl.SocketFrameHandlerFactory.create(SocketFrameHandlerFactory.java:60) ~[amqp-client-5.4.1.jar:5.4.1] at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:1102) ~[amqp-client-5.4.1.jar:5.4.1] at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:1054) ~[amqp-client-5.4.1.jar:5.4.1] at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:994) ~[amqp-client-5.4.1.jar:5.4.1] at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:457) ~[spring-rabbit-2.0.6.RELEASE.jar:2.0.6.RELEASE] ... 9 common frames omitted

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= falsespring.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

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

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

org.springframework.bootspring-boot-starter-parent1.5.2.RELEASE SpringBoot-RabbitMQ SpringBoot-RabbitMQ 0.0.1-SNAPSHOT jar SpringBoot-RabbitMQ http://maven.apache.org UTF-8【SpringBoot停止启动时测试检查rabbitmq操作】UTF-81.8 org.springframework.bootspring-boot-starter-amqporg.springframework.bootspring-boot-starter-actuatororg.springframework.bootspring-boot-starter-web org.springframework.bootspring-boot-maven-plugin

4.配置文件application.properties

spring.application.name=rabbitmq-helloserver.port=8080spring.rabbitmq.hostspring.rabbitmq.host=localhostspring.rabbitmq.port=5672spring.rabbitmq.username=rootspring.rabbitmq.password=root

5.创建入口类

@RestController@SpringBootApplicationpublic 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 {@RabbitHandlerpublic void handlerMsg(String msg) {System.out.println("消息消费者消费===>" + msg); } }}

6.测试

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脚本之家。
