路由间交换文件

Question

我试图解压缩一个文件，并用一个特定的Xpath值单独处理xml文件。下面是Spring。

<camel:route id="unzip-file" startupOrder="400">
    <from uri="file:{{download.folder}}?move={{download.archive}}&amp;consumer.delay=10000"/>
    <unmarshal ref="zipFileDataFormat"/>
    <split streaming="true">
        <simple>${body}</simple>
        <to uri="log:org.apache.camel?level=INFO&amp;showAll=true&amp;multiline=true"/>
        <to uri="file:{{extract.folder}}"/>
    </split>
</camel:route>

<camel:route id="process-extracted-files" startupOrder="300">
    <from uri="file://{{extract.folder}}?noop=true&amp;consumer.delay=10000&amp;delete=false"/>
    <choice>
        <when>
            <simple>${file:ext} regex '(?i)(xml)'</simple>
            <to uri="direct:process-xml-file"/>
        </when>
        <otherwise>
            <log message="ignoring file ${file:name}, not XML"/>
        </otherwise>
    </choice>
</camel:route>

<camel:route id="process-xml-file" startupOrder="200">
    <from uri="direct:process-extracted-files"/>
    <log message="processing file ${file:name}" />
    <choice>
        <when>
            <xpath>/invoices/@region='region1'</xpath>
            <split>
                <xpath>/invoices/invoice</xpath>
                <log message="${body}"/>
            </split>
        </when>
        <otherwise>
            <log message="ignoring file ${file:name}, not 'region1'"/>
        </otherwise>
    </choice>
</camel:route>

我在日志中得到了错误，知道我遗漏了什么。

Answer 1

将子路由定义的URI更改为direct:process-xml-file (与调用相同)

<from uri="direct:process-xml-file"/>
