Spring integration 调度程序没有ftp订阅服务器错误

我有一个文件放置在ftp位置，应该由ftp入站适配器拾取。此文件保存到本地目录。spring文件入站适配器依次轮询此本地目录。FileNameGeneratorbean用于文件入站适配器中，并动态决定目标。我还发布了另一个关于本地目录中的文件未被删除的问题。这就是我面临的问题。 这是我的整个配置

此异常并非每次都出现。 如您所见，我添加了auto startup=“true”。已为通道和适配器使用了唯一id。请让我知道这里出了什么问题

谢谢

首先，您的集成流程不清楚。但我知道你的问题是为了这个

<int-ftp:inbound-channel-adapter id="ftpInbound" channel="ftpChannel"

默认情况下，

阶段

为

0

，因此入站通道适配器可以在出站通道适配器之前启动

---

或者升级到最新版本

我只需要处理这个问题，但需要使用一个文件入站通道适配器。该问题是间歇性的，仅在启动时出现。我认为带有轮询器的适配器可以在Spring集成完全初始化之前开始引入消息

我的修复方法是在启动时禁用适配器。适配器的详细信息并不重要，只是它有一个id，并且设置为“非自动启动”：

  <!--
    Read files from an "inbox" directory, placing them on an "inbox" channel...
  -->

  <int-file:inbound-channel-adapter id="inboxScanner"
                                    directory="$import{inbox}"
                                    auto-create-directory="true"
                                    channel="fileInbox"
                                    prevent-duplicates="false"
                                    auto-startup="false">
    <int:poller fixed-rate="$import{inbox.scan.rate.seconds}"
                time-unit="SECONDS"
                max-messages-per-poll="$import{inbox.max.imports.per.scan}"/>
  </int-file:inbound-channel-adapter>

然后，我点击Spring的应用程序生命周期事件，一旦创建（或刷新）完应用程序上下文，我就告诉适配器开始：

  <!--
    Only start the scanner after the application has finished initializing...
  -->

  <int-event:inbound-channel-adapter event-types="org.springframework.context.event.ContextRefreshedEvent"
                                 channel="contextRefreshEvents"/>

  <int:publish-subscribe-channel id="contextRefreshEvents"/>

  <int:outbound-channel-adapter channel="contextRefreshEvents"
                                expression="@inboxScanner.start()" />

---

“事件”组件来自spring integration event。

是否应该有一个单独的通道，其中ftpinbound适配器从中读取，ftp出站写入？此异常也不一致。现在它运行没有任何问题，这是伟大的，你解决了一个问题，你赢了。如果我的回答有帮助，请接受它，将问题标记为已结束。我已编辑q以添加我的完整配置，因为您说流程不清楚。我还将其更改为对入站和出站使用相同的通道。如果我必须更改配置中的任何内容，请告诉我。我将观察应用程序运行几次，然后得出结论，频道更改是解决方案。请在我的回答中找到
