Question

我有一个spring应用程序，它使用camel来设置从队列中使用的路由。我使用rabbitmq作为消息代理。现在的问题是，如果rabbitmq代理崩溃，连接不会自动恢复。我尝试启用automaticRecoveryEnabled。但我得到noSuchMethodError。我将展示用于创建连接的代码。

<camelContext xmlns="http://camel.apache.org/schema/spring">
        <propertyPlaceholder id="properties" location="file:data/rabbitmq/rabbitmq.properties"/>
        <route>
            <from uri="rabbitmq://{{mete.rabbitmq.host}}:{{mete.rabbitmq.port}}/{{mete.rabbitmq.exchange}}
            ?queue={{mete.rabbitmq.queue}}&amp;username={{mete.rabbitmq.username}}
            &amp;password={{mete.rabbitmq.password}}&amp;exchangeType={{mee.rabbitmq.exchange.type}}
            &amp;queueArgsConfigurer=#myArgs&amp;autoDelete=false&amp;automaticRecoveryEnabled=true&amp;networkRecoveryInterval=654&amp;requestedHeartbeat=987"/>
            <to uri="stream:out"/>
            <process ref="myProcessor"/>
        </route>
    </camelContext>

由于amqp-client依赖性而发生错误。当版本从2.8.4更改为3.5.1时，代码工作正常。新的依赖是：

<dependency>
            <groupId>com.rabbitmq</groupId>
            <artifactId>amqp-client</artifactId>
            <version>3.5.1</version>
</dependency>
