Question

我有以下Spring Integration配置：

<int-file:inbound-channel-adapter
            auto-startup="true"
            channel="localInboundFilesChannel"
            directory="${in.received}"
            auto-create-directory="true">
        <int:poller fixed-rate="60" time-unit="SECONDS"/>
    </int-file:inbound-channel-adapter>

<int-file:outbound-gateway
        auto-startup="true"
        request-channel="localInboundFilesChannel"
        reply-channel="localProcessingFilesChannel"
        directory="${in.processed}"
        auto-create-directory="true"
        delete-source-files="true"
        requires-reply="false"
/>

Poller每1分钟将文件从一个文件夹复制到另一个文件夹，并执行其他操作（我不提供后续步骤的代码）。

但是当我把一些文件放到目录中时，我发现它被读了两次，所以在日志中看到：

2017-08-11 14:06:31,250  INFO  org.springframework.integration.file.FileReadingMessageSource - Created message: [GenericMessage [payload=target\received\request.csv, headers={id=1f4d1ac0-823e-f3b0-2554-caae8e330682, timestamp=1502453191250}]]
2017-08-11 14:06:31,250  INFO  org.springframework.integration.file.FileReadingMessageSource - Created message: [GenericMessage [payload=target\received\request.csv, headers={id=73076423-f1ba-7cbe-a4c2-c5f02220e3f5, timestamp=1502453191250}]]

我该如何解决？ Spring Integrations bean配置中是否存在任何问题？

在声明bean FileReadingMessageSource时，添加一个过滤器org.springframework.integration.file.filters.AcceptOnceFileListFilter。有关更多信息，请参见IntegrationFlows with FileReadingMessageSource triggering job twice for same input file
