<batch:step>: no "transaction-attribute"?

[yannc76]

I'm trying to setup a non-transactional tasklet using MethodInvokingTaskletAdapter in a simple definition like this:

    <batch:job id="indexUpdater">
        <batch:step id="updateIndexes" tasklet="indexUpdaterTasklet"/>
    </batch:job>

  <bean id="indexUpdaterTasklet" class="org.springframework.batch.core.step.tasklet.MethodInvokingTaskletAdapter">
        <property name="targetObject" ref="indexUpdaterService"/>

[...]

Unfortunately, I cannot directly set the required "transaction-attribute" on a <batch:step>-element. Using <batch:tasklet> is not an option, since I don't have any readers/writers.

Would the addition of this attribute make sense or is there an other preferred way of achieving this?

Thanks,
Yann

I've created the following issue to track this: http://jira.springframework.org/browse/BATCH-1131

What do you mean by a non-transactional tasklet? I guess you could provide your own implementation of AbstractStep.

Indeed, I figured a solution using plain <bean>-style configuration with TaskletStep and setting transactionAttribute directly.

I have the same problem and I solved it injecting a "ResourcelessTransactionManager" to my non-transactional tasklet:

<bean id="resourcelessTransactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />

<batch:tasklet ref="myTasklet" start-limit="1" transaction-manager="resourcelessTransactionManager" />

I found another way to do it:

<batch:tasklet ref="myTasklet">
    <batch:transaction-attributes propagation="NOT_SUPPORTED" /> 
</batch:tasklet>
