Problem with overriding transaction settings

[Zico]

Hi all,

I've got a problem with setting my transaction settings in SpringBatch
For special components, I want to specify a different transaction (actually, no transaction at all).

I've writen this :

<aop:config>
   <aop:pointcut id="transactional" expression="execution(* mypackage.batch.*.*(..))" />
   <aop:advisor pointcut-ref="transactional" advice-ref="txAdvice" order="0"/>
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
   <tx:attributes>
      <tx:method name="*" propagation="NEVER"/>
   </tx:attributes>
</tx:advice>

And what I see in my log is

Adding transactional method[*] with attribute [PROPAGATION_NEVER,ISOLATION_DEFAULT]

So I guess it take in account my configuration

But, I still see this

Creating new transaction with name [null]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT

I'm new in Spring Batch and in transaction too. So, maybe I'm doing something wrong.
Could you help please ? Thanks.

I'm using WebLogicJtaTransactionManager as a transactionManger, maybe this has something to do with it ?

You can specify the transaction manager and the transaction attributes on the <tasklet/> element of a <step/>.

  <step id="step1">
      <tasklet transaction-manager="myTxMgr">
          <chunk reader="itemReader" writer="itemWriter" commit-interval="2"/>
          <transaction-attributes isolation="DEFAULT" propagation="REQUIRED" timeout="30"/>
      </tasklet>
  </step>

Yes, I agree. But, actually I'd like to specify different kind of transaction for itemReader, itemProcessor and itemWriter.
For example, "PROPAGATION_REQUIRED" for code in read() and write()
and "PROPAGATION_NEVER" for code in readError(), afterRead(). For logging in databe for instance.
I guess there is a way to do this ?

Actually, I'm trying to do what is explained in section 11.1 of the Spring Batch Documentation.
But it does not work. My aopconfig is not taken in account.

Please, help !

I think by default listeners are in requires new propagation, but I'd have to double check. (It might only be the skip listeners) You should be able to use @Transactional though. Your AOP issues may be pointcut related, its tough to say without seeing the actual config.

Hi, I've tried to add the @Transactionnal tag to my method and....it seems to work ! Great !
I don't understand why it works better than the aop config I've tried but, anyway, it works. That's all I want.
Thanks a lot for your help !

Usually when that happens it's because the pointcut expression is slightly off. It's kind of like a regular expression in that way. (AJDT can help make sure it's actually applying it where you think it is)
