如何在camel XML路由中删除部分文件名

Question

<route id="outboundoFtpPoller">
    <from uri="file:/generatedFiles?move=done/${date:now:yyyyMMdd}/${file:name}&amp;moveFailed=failed/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}"/>
    <to uri="ftp:{{ftp.server}}{{ftp.subdirectory}}/outbox/<what goes here?>" />
</route>

Answer 1

您可以添加这个处理器，它在将文件发送到ftp生成器之前使用正则表达式设置文件名

<route id="outboundoFtpPoller">
    <from uri="file:/generatedFiles?move=done/${date:now:yyyyMMdd}/${file:name}&amp;moveFailed=failed/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}"/>
    <bean id="myProcessor" class="mypackage.MyProcessor"/>
    <to uri="ftp:{{ftp.server}}{{ftp.subdirectory}}/outbox/<what goes here?>" />
</route>

我的处理器在哪里

public class MyProcessor implements Processor {
    @Override
    public void process(Exchange exchange) throws Exception {
        String fileName = exchange.getIn().getHeader(Exchange.FILE_NAME_ONLY, String.class).replaceAll("-\\d+", "");
        exchange.getIn().setHeader(Exchange.FILE_NAME,fileName);
    }
}

不使用处理器更新尝试添加此

  <setHeader headerName="CamelFileName">
            <simple>${in.header.CamelFileName.replaceAll("-\d+","")}</simple>
        </setHeader>
