to simple: delete a file using just one Spring Integration element [Help]

[uzor]

Hi everybody;

Actually i'm using an int:service-activator which calls a java method in order to delete a txt file. This solution is not elegant and I would like do the deletion without use any java class, something like:

<file:something id="delFile" channel="toDel" directory="path"  delete-source-files: "true"/>

is it possible to do something like that?

Thanks!

If the payload is a java.io.File...

<int:service-activator input-channel="toDel" expression="payload.delete()" output-channel="nullChannel" />

If you want to test success/failure to delete, route the output to a channel - the payload will be a Boolean (result of java.io.File.delete()).

Thanks for the answer, but in the payload is not the file, the only thing related with the file is stored in the header and is a peace of the name of the file. To create the file i did the following:

<file:outbound-channel-adapter id="fileout" channel="toStart" directory="${temporal.path}"  filename-generator-expression="headers[messageId].substring(3)+'.txt'"/>

The idea would be something like that:

<int:service-activator id="deleteFile" input-channel="todeleteFile" output-channel="outscreen"
		expression="getResource(${temporal.path}+headers[messageId].substring(3)+'.txt').delete()"/>

Thank!
