should be able to dynamically set the output file name with the timestamp

[cyberneo45]

Hi,
I would like to know, how should I be able to dynamically set the output file name with the timestamp and write to a desired destination.

currently iam hardcoding it like this,

<beans:bean id="flatFileWriter" class="org.springframework.batch.item.file.FlatFil eItemWriter">
<beansroperty name="resource" value="file:d:/SAMPLE-200709.txt" />
<beansroperty name="lineAggregator">
<beans:bean class="org.springframework.batch.item.file.transfo rm.DelimitedLineAggregator">
<beansroperty name="delimiter" value=","/>
</beans:bean>
</beansroperty>

I want this file name to be dynamic with my own PREFIX followed by date.(SAMPLE200709.txt)Any ideas................

You can leverage late-binding to take in the output file name as a job parameter and pass it to the writer.

http://static.springsource.org/sprin...l#late-binding

<property name="resource">
	<bean class="org.springframework.core.io.FileSystemResource">
		<constructor-arg value="#{jobParameters[outputFile]}"/>
	</bean>
</property>

Alternatively, if you don't want to pass the date as a parameter, you can create a custom Resource implementation that wraps a real Resource but generates the filename at runtime. This is what the former StepExecutionResourceProxy did: https://fisheye.springsource.org/bro...xy.java?r=1778

P.S. Use CODE tags instead of QUTOE tags for code.
