File Support with directory at Runtime

[sambaran]

I want the directory info to pass it to the file outbound gately for writing. Is something liek this possible ? I do not see the file getting written


<

file:outbound-channel-adapter directory="headers.FILE_ROOT_DIR" 
	    			channel="fileWriteChannel" filename-generator="customeFIleNmaeGen" auto-create-directory="true"/>

Could you please rephrase the question? I am not sure what you are asking. You can get more details about File support from this section of the reference manual http://static.springsource.org/sprin...lsingle/#files
Also, look at this sample which may help https://github.com/SpringSource/spri...ter/basic/file

Hi Oleg I will take a look.
I will try to re-phase my question. What I want is, to get the directory values using Spel and get the header value (say FILE_DIR) from the message instead of a externalized property file for example. So in my use case I cannot really determine what directory to write until later the request has been placed. For example each client will have root directory + client name as the directory, the file will be written to.
So what I really need is to construct the directory structure based on the type of request.

Like I said go through the sample, make sure it works for you first.
Since SI 2.1 we have this new attribute as well

filename-generator-expression which allows you to provide a SpEL expression which will compute the file name of the target file (e.g., assuming payload is java.io.File "payload.name + '.transferred'");

I think this is what you are looking for

I looked into the sample but still did not find my answer. I know about the file name generator. I am using 'filename-generator', but the problem is not with the file name it is the directory name. I do not see a file-directory-generator for example.

In the sample

<file:outbound-channel-adapter id="filesOut" directory="file:${java.io.tmpdir}/spring-integration-samples/output"/>

I want the directory part to be constructed using Spel from header values.

Used service activator with commons file utils ..., if anyone is interested
