Question

在将消息发布到Rabbit MQ Exchange时，很少有消息丢失。例如，发布了10条消息，只有5条消息被传送到绑定队列，其余5条消息丢失。请指教。

以下是用于连接的Spring XML配置

 <bean id="cachingConnectionFactory" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory" destroy-method="destroy">
    <property name="addresses" value="example.com:8080"/>
    <property name="username" value="guest" />
    <property name="password" value="guest" />
    <property name="virtualHost" value="guest-app" />
    <property name="connectionTimeout" value="1000"/>
    <property name="cacheMode" value="#{T(org.springframework.amqp.rabbit.connection.CachingConnectionFactory.CacheMode).CONNECTION}"/>
    <property name="channelCacheSize" value="6000"/> 
    <property name="channelCheckoutTimeout" value="60000"/>
    <property name="requestedHeartBeat" value="30"/>
    <property name="publisherConfirms" value="true"/>
    <property name="publisherReturns" value="true"/>
</bean>

以下是Rabbit Template Config

    <rabbit:template id="amqpTemplate" connection-factory="cachingConnectionFactory" mandatory="true" retry-template="retryTemplate" /> 
<bean id="retryTemplate" class="org.springframework.retry.support.RetryTemplate">
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.ExponentialBackOffPolicy">
            <property name="initialInterval" value="500" />
            <property name="multiplier" value="10.0" />
            <property name="maxInterval" value="10000" />
        </bean>
    </property>
</bean>
<rabbit:admin connection-factory="cachingConnectionFactory" />

以下是发布消息

int:chain input-channel="output">
      <int:header-enricher>
            <int:header name="amqp_deliveryMode" value="PERSISTENT" type="org.springframework.amqp.core.MessageDeliveryMode"/>
    </int:header-enricher> 
    <int-amqp:outbound-channel-adapter id="outboundAmqp" amqp-template="amqpTemplate" exchange-name-expression="headers['exchange']" routing-key-expression="headers['routingKey']" mapped-request-headers="*" confirm-correlation-expression="payload" confirm-ack-channel="msgResponse" confirm-nack-channel="msgResponse" return-channel="msgResponse"/>

在RabbitMQ上使用Spring Integration amqp：outbound-channel-adapter缺少消息
