Spring poller roll back on exception after a particular retry count - spring

Question

My poller fetches data from DB and pass it to a service activator.
If any exception happens in the service activator method,i should roll back the data fetched to its previous state and should again send the same data to the service activater only for a specific retry-count(say 3). **Is it possible to do this in a xml configuration. ? For details i will share the poller configurations and the service activator.
poller.xml
<int-jdbc:inbound-channel-adapter id="datachannel"
query="select loyalty_id,process_id,mobile_uid from TBL_RECEIPT where r_cre_time
=(select min(r_cre_time) from TBL_RECEIPT where receipt_status=0)"
data-source="dataSource" max-rows-per-poll="1"
update="update TBL_RECEIPT set receipt_status=11 where process_id in (:process_id)">
<int:poller fixed-rate="5000">
<int:transactional/>
</int:poller>
</int-jdbc:inbound-channel-adapter>
<int:channel id="errors">
<int:queue/>
</int:channel>
<bean id="poller" class="main.java.com.as.poller.PollerService" />
<int:channel id="executerchannel">
<int:dispatcher task-executor="taskExecutor" />
</int:channel>
<task:executor id="taskExecutor" pool-size="2" />
<int:service-activator input-channel="datachannel"
output-channel="executerchannel" ref="poller" method="getRecordFromPoller">
<int:request-handler-advice-chain>
<int:retry-advice recovery-channel="errors" />
</int:request-handler-advice-chain>
</int:service-activator>
<int:service-activator input-channel="executerchannel"
ref="poller" method="getDataFromExecuterChannel">
</int:service-activator>
service activator method
#SuppressWarnings({ "unchecked", "rawtypes" })
#ServiceActivator
public void processMessage(Message message) throws IOException {
int capLimit = Integer.parseInt(env.getProperty("capping_limit"));
List<Map<String, Object>> rows = (List<Map<String, Object>>) message
.getPayload();
for (Map<String, Object> row : rows) {
String loyaltyId = (String) row.get("loyalty_id");
String processId = (String) row.get("process_id");
String xid=(String)row.get("mobile_uid");
i have heard about int:transactional being used in poller configuration.But when i added it,its taking the same record even after successful transaction.(means its getting rolled back everytime).
Can anyone please help me on this ?

Answer 1

You can add a retry request-handler-advice to the service activator.
To make retry stateful (throw the exception so the transaction will rollback) you need to provide a RetryStateGenerator. Otherwise the thread will simply be suspended during the retries.
Regardless of using stateful or stateless retry, you really should use a transactional poller so that the update is only applied after success.
means its getting rolled back everytime
The transactional poller will only rollback if an exception is thrown. So if you're seeing the same row, something must be failing.
Turn on DEBUG logging for all of org.springframework to follow the message flow and transaction activity.
