尚未为端点出站适配器定义轮询器

Question

我收到这个错误

“尚未为端点‘importExchangesOutboundAdapter’定义轮询器”。下面是我的 Spring 批量远程分块配置。

我正在使用 spring 集成 amqp。

<rabbit:connection-factory id="connectionFactory"
    port="${rabbitmq.port}" host="${rabbitmq.host}" username="${rabbitmq.username}"
    password="${rabbitmq.password}" />

<rabbit:template id="amqpTemplate"
    connection-factory="connectionFactory">
</rabbit:template>

<rabbit:queue name="${import.exchanges.queue}" />
<rabbit:queue name="${import.exchanges.reply.queue}" />

<int:channel id="importExchangesChannel">
    <int:queue />
</int:channel>


<int:channel id="importExchangesReplyChannel">
    <int:queue />
</int:channel>


<beans:bean id="importExchangesMessagingTemplate"
    class="org.springframework.integration.core.MessagingTemplate"
    p:defaultChannel-ref="importExchangesChannel" p:receiveTimeout="${import.exchanges.reply.timeout}">
</beans:bean>

<amqp:outbound-channel-adapter id="importExchangesOutboundAdapter"
    channel="importExchangesChannel" />

<amqp:inbound-channel-adapter id="importExchangesInboundAdapter"
    connection-factory="connectionFactory" channel="importExchangesReplyChannel"
    queue-names="${import.exchanges.reply.queue}" />


<beans:bean id="importExchangesChunkItemWriter"
    class="org.springframework.batch.integration.chunk.ChunkMessageChannelItemWriter"
    scope="step" p:messagingOperations-ref="importExchangesMessagingTemplate"
    p:replyChannel-ref="importExchangesReplyChannel">
</beans:bean>

<beans:bean id="importExchangesChunkHandler"
    class="org.springframework.batch.integration.chunk.RemoteChunkHandlerFactoryBean"
    p:chunkWriter-ref="importExchangesChunkItemWriter" p:step-ref="importExchangesStep">
</beans:bean>

<amqp:inbound-channel-adapter id="importExchangesSlaveInboundAdapter"
    connection-factory="connectionFactory" channel="${import.exchanges.queue}Channel"
    queue-names="${import.exchanges.queue}" />



<amqp:outbound-channel-adapter id="importExchangesSlaveOutboundAdapter"
    channel="importExchangesReplyChannel" />

<int:service-activator id="serviceActivatorExchanges"
    input-channel="importExchangesChannel" output-channel="importExchangesReplyChannel"
    ref="chunkProcessorChunkHandlerExchanges" method="handleChunk" />

<beans:bean id="chunkProcessorExchanges"
    class="org.springframework.batch.core.step.item.SimpleChunkProcessor"
    p:itemWriter-ref="importExchangesItemWriter" />

<beans:bean id="chunkProcessorChunkHandlerExchanges"
    class="org.springframework.batch.integration.chunk.ChunkProcessorChunkHandler"
    p:chunkProcessor-ref="chunkProcessorExchanges" />

Answer 1

您定义的端点 importExchangesOutboundAdapter 有频道的 importExchangesChannel 轮询消息，因为该通道是 Queue 需要配置轮询器以进行消息消费的通道。

简单的答案是定义一个全局轮询器，如下所示：

<int:poller default="true" fixed-delay="100"/>
