How to post on multiple queues using single job/ J

问题:

I am a newbie at Spring Batch and have recently started using it.

I have a requirement where I need to post/write the messages read from each DB record on different queues using single Job. As I have to use reader to read the messages from DB and use processor to decide on which queue I have to post it.

So my question is Can I use single JMSwriter to post the messages on different queues as I have to use single Job and DB Reader.

Thanks in Advance

As I know JMSwriter not supports it (it writes to default destination of jmsTemplate).

But you may just implement your own ItemWriter, inject all jmsTemplates in it and write custom decistion logic to select appropriate destionation and write to it.

Another way - use ClassifierCompositeItemWriter , put a set of JmsWriters to it and select one by your classifier
