将文件移动到多个位置的正确方法

我继承了一些需要修改的旧骡子流，我想知道处理以前做过的正确方法。

电流：

<processor-chain doc:name="Processor Chain">
    <all doc:name="All">
        <file:outbound-endpoint
        path="archive"
        outputPattern="#[header:INBOUND:originalFilename]_#[function:datestamp:${standard.date.format}]_#[function:systime]"
        responseTimeout="${standard.response.timeout.millis}"
        doc:name="File Archive"/>
        <file:outbound-endpoint
        path="inbound"
        outputPattern="${brand.name}.refresh.#[function:datestamp:${standard.date.format}]_#[function:systime]"
        responseTimeout="${standard.response.timeout.millis}"
        encoding="UTF-8"
        doc:name="Inbound"/>
        <logger level="WARN" message="Downloaded file to inbound/${brand.name}.refresh" doc:name="Download File Logger"/>
    </all>
</processor-chain>

看到All被弃用了，他们说要使用Scatter Gather我试过这个：

<processor-chain doc:name="Processor Chain">
    <scatter-gather doc:name="Scatter-Gather">
        <file:outbound-endpoint
            path="archive"
            outputPattern="#[header:INBOUND:originalFilename]_#[function:datestamp:${standard.date.format}]_#[function:systime]"
            responseTimeout="${standard.response.timeout.millis}"
            doc:name="File Archive"/>
        <file:outbound-endpoint
            path="inbound"
            outputPattern="${brand.name}.refresh.#[function:datestamp:${standard.date.format}]_#[function:systime]"
            responseTimeout="${standard.response.timeout.millis}"
            encoding="UTF-8"
            doc:name="Inbound"/>
        <logger level="WARN" message="Downloaded file to inbound/${brand.name}.refresh" doc:name="Download File Logger"/>
    </scatter-gather>
</processor-chain>

但这给了我以下例外：

从FTP站点获取文件并将其转储到这样的两个位置的推荐方法是什么？

2 个答案:

答案 0 :(得分：2)

你刚遇到一个错误，请看看这个issue。它固定在3.6.0，当然还有3.6.1。 尝试在端点之后添加消息处理器作为解决方法，如JIRA票证中所述。

答案 1 :(得分：-1)

在你的scatter-gather定义中删除处理器链范围，并在itadd对象到字符串变换器之前。
