Using {date:..} placeholder in camel-context endpoint

[roger_rabbit <ro...@gmx.fr>]

Hi,

I am wondering whether it is possible to use a ${date:now:yyyyMMdd} on an
endpoint in my camel context file, in order to specify a date-related
endpoint (my endpoint will change everyday according to date).

I tried something such as : 
    <endpoint id="com.my.dir.out"
uri="file:${com.my.params.dir.out}/${date:now:yyyyMMdd}?autoCreate=true" />

but this didn't work : the first parameter "/com.my.params.dir.out/" was
parsed, but the date was instead replaced by "now:yyyyMMdd" (I also tried
something stupid such as : ${date:${date:now:yyyyMMdd}}, but this lead to
same result, indeed...):

/C​a​n​n​o​t​ ​p​o​l​l​ ​a​s​ ​d​i​r​e​c​t​o​r​y​ ​d​o​e​s​ ​n​o​t​
​e​x​i​s​t​s​ ​o​r​ ​i​t​s​ ​n​o​t​ ​a​ ​d​i​r​e​c​t​o​r​y​:​
​d​:​\​t​m​p​\​c​a​m​e​l​\out\​n​o​w​:​y​y​y​y​M​M​d​d/

Is there anyway to use the date that way in context-file?

For information, my route are defined in a RouteBuilder class, and not in
the camel-context file.

Thanks in advance!

Thank you Claus, 

this worked.
Eventually, I ended up changing the whole thing... because I read  somewhere
<http://camel.465427.n5.nabble.com/read-all-files-in-folder-td4474104.html#a4478126>  
that 
"not every possible use case is a perfect fit in camel"* :)


Thus, I will have other problems... but that one is no more!

Thanks again for your kind help.

* : this should be sticked, cause this sentence really often makes sense!

Hi

Yeah use baseFolder as the starting directory. And then use
/${date:now:yyyyMMdd} as prefix for the the file name.

....?fileName=${date:now:yyyyMMdd}/${file:name}

For the name of the file you can use the file language (part of simple
language), see
http://camel.apache.org/file-language.html

There is some examples here

Thank you for your answer.

I understand I can use a custom filter to filter directory based including
the date I want to process, but not sure it is suited for creating a
directory with such rule :
=> "write to a directory named /tmp/${yyyyMMdd} and create it if it does not
exist". 

For the moment, I also tried creating the endpoint in my Route Builder :

			this.folderOut = "file:"+
				  baseFolder+
				  "/${date:now:yyyyMMdd}?autocreate=true";

But I got an exception saying :
/Dynamic expressions with ${ } placeholders is not allowed. Use the fileName
option to set the dynamic expression./

Hi

You can use a filter on the file endpoint to filter the directory and
file names you want.
