Spring Boot RabbitMQ连接重试配置

Question

我有与rabbitmq的spring boot cloud微服务，我使用docker-compose启动所有容器。 Rabbitmq需要一些时间来启动，在完成启动之前，我看到了很多连接尝试：

config-service_1          | 2019-06-22 16:13:13.351  INFO 6 --- [pool-2-thread-2] o.s.a.r.c.CachingConnectionFactory       : Attempting to connect to: rabbitmq:5672

如何为Rabbitmq连接配置重试超时？
我没有找到任何spring.rabbitmq.**属性来执行此操作。

更新

已发现问题，但仍无法解决。
我有一个日志记录配置，可通过Rabbitmq附加程序发送日志，这是logback-spring.xml ：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <springProperty scope="context" name="appName" source="spring.application.name"/>
    <springProperty scope="context" name="rabbitMqHost" source="spring.rabbitmq.host" defaultValue="localhost"/>
    <springProperty scope="context" name="rabbitMqPort" source="spring.rabbitmq.port" defaultValue="5672"/>
    <springProperty scope="context" name="rabbitMqUsername" source="spring.rabbitmq.username" defaultValue="guest"/>
    <springProperty scope="context" name="rabbitMqPassword" source="spring.rabbitmq.password" defaultValue="guest"/>
    <appender name="AMQP" class="org.springframework.amqp.rabbit.logback.AmqpAppender">
        <host>${rabbitMqHost}</host>
        <port>${rabbitMqPort}</port>
        <username>${rabbitMqUsername}</username>
        <password>${rabbitMqPassword}</password>
        <applicationId>${appName}</applicationId>
        <contentType>application/log</contentType>
        <exchangeName>gc.log</exchangeName>
        <declareExchange>true</declareExchange>
        <deliveryMode>NON_PERSISTENT</deliveryMode>
        <charset>UTF-8</charset>
        <layout>
            <pattern>
                ${appName}
                %date{"yyyy-MM-dd'T'HH:mm:ss.SSSXXX", UTC}
                %thread
                %level
                %logger{36}
                %message
            </pattern>
        </layout>
    </appender>
    <root level="INFO">
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="AMQP"/>
    </root>
</configuration>

如果我删除此配置，一切正常。
因此，现在的问题是如何为AmqpAppender配置连接工厂恢复间隔

Answer 1

它当前没有显示为Boot属性，但是您可以在Rabbit侦听器容器工厂上设置recoveryInterval或recoveryBackOff 。

只需在某些配置类中获得对容器工厂的引用（或覆盖Boot的默认自动配置工厂）并设置属性即可。

例如

@Bean
public Object configure(SimpleRabbitListenerContainerFactory factory) {
    factory.setRecoveryInterval(10_000L);
    return null; // you can return null as long as you are on Boot 2.x.
}

请打开“启动改进GitHub”问题以将其公开为属性。

编辑

您最初的问题没有提到您使用RabbitMQ仅用于日志记录。 以后，请在问题中更加清楚，以便及时获得正确的答案。

上面的答案适用于尝试连接到代理的@RabbitListener方法。

由于日志记录是“发布”事件，因此，每次您尝试发送日志（并进行重试）时，都会进行一次连接尝试，因此您将获得该INFO日志。

抑制这些日志的唯一方法是将org.springframework.amqp.rabbit.connection.CachingConnectionFactory的日志级别更改为WARN。
