Spring Boot RabbitMQ連接重試配置

Question

我有與rabbitmq的spring boot cloud微服務，我使用docker-compose啟動所有容器。 Rabbitmq需要一些時間來啟動，在完成啟動之前，我看到了很多連接嘗試：

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

如何為Rabbitmq連接配置重試超時？
我沒有找到任何spring.rabbitmq.**屬性來執行此操作。

更新

已發現問題，但仍無法解決。
我有一個日志記錄配置，可通過Rabbitmq附加程序發送日志，這是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>

如果我刪除此配置，一切正常。
因此，現在的問題是如何為AmqpAppender配置連接工廠恢復間隔

Answer 1

它當前沒有顯示為Boot屬性，但是您可以在Rabbit偵聽器容器工廠上設置recoveryInterval或recoveryBackOff 。

只需在某些配置類中獲得對容器工廠的引用（或覆蓋Boot的默認自動配置工廠）並設置屬性即可。

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.
}

請打開“啟動改進GitHub”問題以將其公開為屬性。

編輯

您最初的問題沒有提到您使用RabbitMQ僅用於日志記錄。 以后，請在問題中更加清楚，以便及時獲得正確的答案。

上面的答案適用於嘗試連接到代理的@RabbitListener方法。

由於日志記錄是“發布”事件，因此，每次您嘗試發送日志（並進行重試）時，都會進行一次連接嘗試，因此您將獲得該INFO日志。

抑制這些日志的唯一方法是將org.springframework.amqp.rabbit.connection.CachingConnectionFactory的日志級別更改為WARN。
