LocalContainerEntityManagerFactoryBean hibernate configuration bean is initialized in a loop - spring-4

Question

I have my hibernate entity manager factory declared in jpa.xml, hazecast configured in hazelcast.xml and I have domain model setup and I have corresponding componentContext.xml present in the domain model project where my entity manager factory class is implemented in it. But the problem I am
facing is that my bean in componentContext.xml is getting intialized in a loop (observed from hibernate.log)
My Web.xml has only com.sun.faces.config.ConfigureListener listenere configured.

I have tried debugging multiple times but I am not able to figure out why the initialzing is happening multiple times (as if in a loop). Any pointers greatly appreciated!

Answer 1

I finally figured out the reason! There was an additional #ComponentScan annotation specified in the application configuration class which was causing the loop to be triggered.
