Apache Camel无法与Groovy一起使用

Question

My original issue is that I want to use System.currentTimeMillis() as fileName.
Try1

{date:now:SimpleDateFormat}

does not support it. I can print Milliseconds with S but its difference from the previous second.
Try2 Tried using inline groovy dsl but got error. I think this was a wrong approach but I love to have inline Scripting language support in Camel

<to uri="file://D:/Projects/?fileName=TestPipeline_$groovy{new Date()}.txt"/>

Try 3 Now I have lowered my expectation and thought to use groove straight forward. As a first pass tried Sping DSL example by just writing

<groovy>new Date()</groovy>

But application context doesn't recognize groovy tag.

Invalid content was found starting with element 'groovy'. One of

I am using Camel 2.9.2 and included camel-groovy-2.9.2.jar in lib folder.

Answer 1

I think you have the error on your 3rd try because <groovy> is only allowed in <translate> <setBody> or <setHeader> (there might be other options).

I'd try something like:

edited

<setHeader headerName="nowInMillis">
    <groovy>new Date().getTime()</groovy>
</setHeader>
<log message="/////////////// ${in.header.nowInMillis}" loggingLevel="INFO"/>
<to uri="file://D:/Projects/?fileName=TestPipeline_${in.header.nowInMillis}.txt"/>

Hope this helps, Gergely
