I want to create a spring-batch job, but I want to run it without any database persistence.

How can I read items from multiples databases? I already know that is possible from files. the following example works for read from multiples files ... <job id="readMultiFileJob" xmlns="http://www.springframework.org/schema/batch"> <step id="step1"> <tasklet> <chunk reader="multiResourceReader" writer="flatFileItemWriter" commit-interval="1" /> </tasklet> </step> </job> ... <bean id="multiResourceReader" class=" org.springframework.batch.item.file.MultiResourceItemReader"> <property name="resources" value="file:csv/inputs/domain-*.csv" /> <property name="delegate" ref="flatFileItemReader" />
