Apache camel 处理文件和删除时从Camel配置中获取一些问题

处理文件和删除文件时，从Camel配置中获取一些问题。在下面添加了3个用例

目标：使用SFTP读取文件并将其复制到本地目录中。完成后，将其从SFTP位置删除。下面是配置

<from uri="sftp://xxxx@xxxxxx:xxxx/testFolder/ToClient/?password=xxx& delete=true& scheduler=spring& scheduler.cron=0/15+*+*+?+*+MON-SAT& antInclude=*OECExport *.txt"/>

用例3:其中有多个文件

新属性：disconnect=true

属性：

处理：未按预期工作。 警告:

解决了

将.split（）.body（）添加到动态管线定义中。或者您甚至可以将其添加到您的路线中，如下所示

<route id="sftp-processor1" xmlns="http://camel.apache.org/schema/spring">
    <description lang="en">sftp-processor1</description>
    <from uri="sftp://xxx@xxx:xxx/testFolder/ToClient/?password=xxx&stepwise=false&delete=true&scheduler=spring&amp;scheduler.cron=0/15+*+*+?+*+MON-SAT&antInclude=*TestFile*"/>
    <split id="split36">
        <expressionDefinition>body</expressionDefinition>
        <setHeader headerName="CamelFileName" id="setHeader346">
            <simple>${file:name.noext}_${date:now:yyyyMMdd-hhmmss.SSS}.${file:name.ext}</simple>
        </setHeader>
        <to uri="file:/home/test/inbound/?readLock=changed"/>
    </split>
</route>

sftp-processor1
身体
${file:name.noext}{date:now:yyyyMMdd hhmmss.SSS}.${file:name.ext}

尝试使用stepwise=false。如果您使用InputStream或其他方法读取文件内容，请确保关闭它们，以避免泄漏。我尝试使用stepwise=false，但它仍然会给我带来相同的问题。我没有使用任何流来读取文件内容，即使是这样，如果每5分钟进行一次轮询，并且有两个文件，那么在第一次轮询中，它会处理一个带有警告消息的文件，然后在5分钟后，它轮询第二个文件。可能您对该文件的自定义处理正在锁定某些资源，因此文件句柄/流不能自由地在以后删除该文件。
