No Hibernate Session bound to thread
Problem:
I hit an error “No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here” while I’m doing unit testing in an application that combining Spring Batch and Hibernate. This problem exists when I try to do some data insertion at the Spring Batch Listener.
Solution:
The root of this problem occurred is because there is NO hibernate session at the Spring Batch Listener level. How come?!?! Its because the AOP pointcut I defined and use throughout the application is at the Batch JobRepository
<aop:config>
<aop:advisor pointcut="execution(* org.springframework.batch.core..*Repository+.*(..))"
advice-ref="txAdvice" />
</aop:config>
But the Batch Listener is not under the same / child package of the JobRepository. The Listener is under org.springframework.batch.core.StepExecutionListener. To ease the configuration, I add in another pointcut at my business package my.com.company.project.writer.MyItemWriter.beforeStep.
The AOP pointcut I added is:
<aop:config>
<aop:advisor pointcut="execution(* my.com.pv.batch.report.writer.CdrItemWriter.beforeStep(..))"
advice-ref="txAdvice" />
</aop:config>
Lessons Learned:
1. Identified where is the point cuts, is that the existing pointcut is enough for me?
